--- Rename of Lynx2-4-FM and release as Lynx2-5  (02-May-1996) ---

==============================================================================

05-02-96 ---- Release of Lynx2-5 ----

* Modified documentation, help, and example files based on feedback for

  yesterday's Lynx2-5 pre-release. - FM

* Include ";q=0.001" whenever "iso8859-1" or "us-ascii" are autoappended

  to Accept-charset headers. - FM

* Added SITE_LIBS symbol in Makefile for convenient linking to any

  site-specific libraries associated with any site-specific patches. - FM

* Fixed an unsigned char typecast in GridText.c - FM

* Eliminated statusline and TRACE warnings about possibly strange formatting

  when TABLEs are in a document. - FM

05-01-96

* Renamed Lynx2-4-FM for pre-release as Lynx2-5

04-30-96

* Modified the fatal error messages such that they direct the user to

  the local system administrator to confirm a bug before reporting it

  to lynx-dev, and started updated the help and about files for the

  switch to lynx-dev@sig.net as the primary list server. - FM

04-28-96

* Made use of ordered versus unordered lists and inclusion of article dates

  in listings for news groups compilation and configuration options in

  userdefs.h and lynx.cfg. - FM

04-27-96

* Added -realm switch for restricting URLs to the realm of the startfile.

  The bookmark and jumps files are always considered as part of the realm.

  Any execution links or form ACTIONs are permitted if obtained from

  documents in the realm, but any switches that restrict bookmark operations

  will still apply.  For example, -book -realm will use the bookmark file

  as the startfile, and restrict URLs to files in the user's account.  Adding

  -restrictions=bookmark_exec will block execution links in the bookmark

  file, but not in other files within the realm (i.e., in the user's

  account).  If the startfile is an http URL, the realm will be equivalent

  to that in http authorization procedures.  Can be used with -traversal

  for restricting the traversal to documents within the starting realm

  for an http server. - FM

* Fixed bug in form structure which could cause POST to be treated as

  GET. - FM

04-25-96

* Added code to send Host: headers as described in the 23-Apr-96 HTTP/1.1

  draft. - FM

04-23-96

* Modified HTMIME.c to pass documents with an ISO-8859-3 through -9, EUC-KR,

  or ISO-2022-KR charset specified in the Content-Type header, to set the

  flag for not doing 8-bit reverse translations, and to issue a statusline

  message about the charset instead of forcing a download offer.  Will have

  garbage in the displays of 8-bit characters if one doesn't have the

  corresponding charset installed for the terminal, but no harm should be

  done, and those who do can get the files displayed instead of just being

  up the creek without a paddle.  Korean escape sequences will still be

  trashed, since be have no translation functions as for Japanese, and we

  still force a download offer if there is a mismatch for the supported

  character sets, so the user can cancel and then modify the terminal setup

  and charset choice appropriately. - FM

* Increased the maximum number of attributes for tags (was too small for

  OBJECT), updated the DTD for SCRIPT, and added the STYLE attribute for

  all tags which presently, or might someday, accept it. - FM

04-21-96

* Modified the news gateway to use an ordered list with the numbers and

  dates of the articles indicated in newsgroup listings. - FM

* Fixed the checking and passing of the mailto argument in LYMainLoop.c

  to mailmsg() in LYMail.c. - FM

04-20-96

* Fixed bugs in parsing of nntp and snews partial HREFs, and in the

  parsing of NNTP message headers for creation of mailto and newspost

  or newsrepy links. - FM

04-19-96

* Added OBJECT and BODYTEXT to the DTD, based on the 12-Apr-96 W3C draft.

  The code for INSERT is still there, and should be remove if OBJECT

  becomes a stable replacement.  Code to handle data URLs for OBJECTs

  not yet attempted. - FM

* More tweaks for Japanese character handling. - FM

04-18-96

* If LINKS_ARE_NUMBERED is on, include the list of references in the

  outputs of 'p'rint menu options, analogously to the output with

  -dump. - FM

04-14-96

* Mods to report the content of SCRIPT, STYLE and ALIAS blocks in trace

  mode. - FM

* Made ¨, ¯ and ™ synonyms for ¨, &hibar; and ®,

  respectively. - FM

* Fixed typo in second line link highlighting code for slang. - ES

04-13-96

* More tweaks of Japanese character handling. - FM

* Reinitialize timeout values after select() calls in LYUtils.c. - ES

04-12-96

* More tweaks of Japanese character handling. - FM

* Tweak of target line and link setting when toggling to image_links mode

  in LYMainLoop.c. - FM

* Tweaks of circular buffer handling based on analyses from Mike Castle

  (mcastle@umr.edu) and Bryan T. Vold (btv@ldl.HealthPartners.COM). - FM

* Fixed typo for NeXT in tcp.h, based on feedback from LWV - FM

* Reinitialize timeout values after select() calls in HTTCP.c. - Erik

  Sundkvist (ess@lysator.liu.se)

04-11-96

* More tweaks of Japanese character handling. - FM

* Added code for handling charset mappings for file and ftp URLs. - FM

  You can set the mappings via lynx.cfg (or mime.types), e.g.:

  SUFFIX:.html8R:text/html; charset=KOI8-R

  SUFFIX:.txt8R:text/plain; charset=KOI8-R

* Tweak of charset handling in HTMIME.c - FM

04-09-96

* Modified news gateway to handle split header lines. - FM

* Tweaks of authorization header handling to make failures due to bad

  headers from the http server clear to the Lynx user. - FM

04-08-96

* Yet more tweaks of memory management. - FM

04-07-96

* Tweaks for handling Japanese received via gateways. - FM

04-06-96

* More memory management tweaks. - FM

04-05-96

* Updated lynx.man, lynx.hlp and the online help files. - FM

* Tweaks of INPUT, TEXTAREA and SELECT popup OPTION handling when

  Japanese character translations are on. - FM

04-04-96

* Created new zip.  Yesterday's appears to have been bad. - FM

04-03-96

* More optimizations and bug fixes based on patches from JED. - FM

* More mods for handling keyboard input via SLANG library functions,

  based on patches from JED.  Note that the code for IGNORE_CTRL_C

  has been bypassed in those mods, as they presently stand. - FM

04-02-96

* Added "first pass" handling of P end tags. - FM

* Mods of HTCheckForInterrupt() for SLANG, based on patches from JED.

  Note that the for-SLANG code is not taking possible SOCKSification of

  Lynx into account. - FM

* Use 3 for ^C instead of 7 for ^G as the argument for the slang abort

  key in calls to SLang_init_tty(). - JED

* Tweaks of make for clix. - AM

03-31-96

* More tweaks of memory management. - FM

03-30-96

* Added support for Japanese translations of text/plain in addition to

  text/html documents, and for ALTs and form fields (see 03-26-96 mods).

  Needs checking.  Also added an LYK_JPN_TOGGLE, mapped to '@' by default,

  for toggling JAPANESE mode ON and OFF, and code to indicate the situation

  in the 'o'ptions menu. - FM

* Added make for ultrix-slang and decstation-slang, and tweaks of LYCgi.c

  for ultrix. - Alvian Tam (atm@newt.phys.unsw.edu.au)

* Found and fixed some typos in yesterday's mods. - FM

03-29-96

* Added build-slang.com for building Lynx with the SLANG library instead

  of curses on VMS. - FM

* Mod to treat an EOF with errno of EINTR when GetChar() is defined as

  getchar() in LYgetch() as due to a Ctrl-Z suspend, and invoke another

  character fetch instead of exit on error.  Based on patch from Gregory

  Neil Shapiro (gshapiro@WPI.EDU). - FM

* Numerous optimizations and bug fixes based on patches from JED. - FM

03-28-96

* More tweaks of SLANG support. - FM

* Yet more tweaks of the HTList functions and macros, and their associated

  memory management. - FM

03-27-96

* Fixed bug which could cause a crash if links are numbered and you

  activate a link via a number when there are no links on the currently

  displayed page. - FM

* Tweaks of Content-Encoding header handling, and more detailed messages

  about it in trace mode. - FM

03-26-96

* Added code in HTMIME.c for taking into account Content-Encoding headers,

  so that compressed text/html or text/plain files are not displayed

  inappropriately based on their Content-Type. - FM

* Added "first pass" support for Japanese character translations, based on

  patches for Lynx2-4-1 by Takuya Asada (asada@icsd6.tj.chiba-u.ac.jp).  Is

  to be checked out by Nelson Henry Eric (nelsonhe@ews07.nara.kindai.ac.jp)

  because I have no way to check it here.  Translations can be made the

  default behavior by setting JAPANESE to TRUE in userdefs.h and/or

  lynx.cfg.  The default can be toggled via a "-jpn" command line switch.

  If made TRUE by any means, the value of KANJI_CODE set in userdefs.h

  and or lynx.cfg (EUC, SJIS, or NONE) will be applied, and can be changed

  via "-euc", "-sjis" or "-ascii" command line switches, for setting Kanji

  code translations to EUC, Shift JIS, or disabling it, respectively.  Note

  that Japanese translations are not yet performed in the line editor

  (LYgetstr() of LYStrings.c and form_getstr() of LYForms.c), for form

  field values, or for gateways (let's first see if what I've done so far

  works right 8-) - FM

* Added "LY" prefix for pop(), pop_num() and push() function names to

  avoid possible conflicts with the ncurses library functions, and fixed

  continuation line typo in solaris2 make, based on feedback from PN. - FM

03-23-96

* Tweaks of memory management in the CSO/PH gateway. - FM

* Tweaks of wait() versus waitpid() handling for NeXT, aix4 and mips,

  based on feedback from PN. - FM

03-22-96

* Tweaks of SLANG support for Unix, and finished up code support for it on

  VMS (but tested only with OpenVMS/AXP).  Haven't yet decided how to add

  VMS build support for it in the COM and MMS files.  Get the SLANG library

  code from ftp://space.mit.edu/pub/davis and then add USE_SLANG in the

  DEFINE list and the path to it's headers in the INCLUDE list for the

  compilation, and [path]slang.olb/lib in the link list immediately before

  the OPT file.  We still need the curses library in the OPT file, because

  that's not just curses functions on VMS and we're using ones not replaced

  by the SLANG library (Try it, you'll like it! 8-). - FM

* Tweaks for NeXT, based on feedback from Paul Nevai

  (nevai@ops.mps.ohio-state.edu). - FM

03-20-96

* Tweaks of code for sorting directory listings by date (take into account

  the 6-month-old time versus year rule on Unix). - FM

* Tweaks of memory management for HTList-based buffers (use internal

  allocations, instead of the libwww macros). - FM

* Added solaris2-slang to Makefile, and tweaks of the sun4 makes. - LWV

03-19-96

* Tweak of MAP handling so that the ordered lists are displayed exactly

  in the order of the resolved AREA tags.

03-18-96

* Added SLANG support (for colorized Lynx) based on patches from JED.

  The make support is for linux and sun4, but it should be portable to

  other Unix flavors.  I have it working on VMS, but the SLANG interrupt

  and exit handlers are incompatible with the current ones for VMS in

  Lynx (and with the VMS debugger), so I haven't yet included SLANG

  support in build.com or the MMS files. - FM

03-17-96

* Tweaks of 'd'ownload menu handling on returns to it from a DOWNLOADER

  action. - FM

* Added various anti-crash protections and cleaner code from John E. Davis

  (davis@space.mit.edu) for trimming trailing white space and finding

  unescaped colons in LYReadCFG.c, and cleaned up and more fully commented

  the functions and subfunctions in that and the LYMainLoop.c modules. - FM

03-16-96

* Fixed routine which sorts directory listings by date (based on 'o'ptions

  menu setting) to do it accurately and in reverse chronological order. - FM

03-15-96

* Added code to create links for likely URLs in results returned by

  the CSO/PH and finger gateways.  Try:

   gopher://ns.bradley.edu:105/2   or:

      cso://ns.bradley.edu/        and search for David Henderson.

  Also try:

   gopher://cegt201.bradley.edu:79/0/w%20davidh   or:

   finger://cegt201.bradley.edu/w/davidh          as URL.s - FM

* Added LYK_INTERRUPT handling for the CSO/PH and finger gateways, and

  made their memory management more efficient. - FM

* Made the my_spawn() function in LYLocal.c more portable by using

  waitpid() instead of wait(). - FM

* Restored the Lynx2-3 behavior of seeking the current position and link

  on return from 'e'dit.  May be wrong if the file was modified, but it

  might be in the right ball park, and nothing really bad will happen if

  it's far off. - FM

03-14-96

* Added -reload switch for instructing Lynx to send "Pragma: no-cache" and

  "Cache-Control: no-cache" headers when requesting the startfile from an

  http server (doesn't apply to subsequent fetches, or to non-http startfile

  URLs). - Peter Ekberg (peda@lysator.liu.se)

* Put the correct LYMain.c, which declares no_change_exec_perms, in the zip

  (second try, hope I really did 8-). - FM

03-13-96

* Yet more tweaks of the CSO/PH gateway. - FM

* Yet more tweaks of the finger gateway. - FM

03-12-96

* Made the URL and command buffering in the finger gateway secure from stack

  modifications, beautified the HTLoadFinger() and response() functions, and

  added support for the following URL formats for sending a "", "/w",

  "username", or "/w username" command to the finger server:

     finger://host			   finger://@host

     finger://host/			   finger://@host/

     finger://host/%2fw			   finger://@host/w

     finger://host/w                       finger://host/w/

     finger://host/username[@host]	   finger://username@host

     finger://host/username[@host]/	   finger://username@host/

     finger://host/w/username[@host]	   finger://username@host/w

     finger://host/%2fw%20username[@host]  finger://host/username[@host]/w

* Replaced the _tolower macro in the CSO/PH gateway with TOLOWER. - FM

* Tweaks of DIRED_SUPPORT.  Added NO_CHANGE_EXECUTE_PERMS compilation

  symbol and change_exec_perms restrictions switch for restricting

  changes of the eXecute permissions to directories, and not files,

  when OK_PERMIT has been set. - Earl Fogel (fogel@duke.usask.ca) & FM

* Added make support for Intergraph CLIX (note that some online help files

  must be edited and renamed to meet this Unix flavor's 14 character file

  name limit). - Alex Matulich (matuli_a@marlin.navsea.navy.mil)

03-11-96

* Added support for using finger://host/w/username to send "/w username"

  to finger (port 79) servers. - FM

* Tweaks of alignment handling to deal with (illegally) embedded CENTER

  containers (typically due to omission of an end tag for the first

  CENTER of the pair; ugh!). - FM

03-10-96

* Added form-based CSO/PH (port 105) gateway.  Can be invoked via a

  cso://host[:port]/ or gopher://host[:port]/2 URL.  If the gopher

  format is used and a query token is appended (?[query]), the old

  ISINDEX-based gateway will be used. - FM

03-07-96

* Added NO_FROM_HEADER configuration symbol in lynx.cfg, and -nofrom

  command line switch, for blocking all transmissions of From headers

  by Lynx. - FM

* Added NO_REFERER_HEADER configuration symbol in lynx.cfg, and -noreferer

  command line switch, for blocking all transmissions of Referer headers

  by Lynx. - FM

* Enhancements of the 'o'ptions menu. - FM

03-06-96

* Restored the Lynx2-3 behavior of seeking the current document position

  and link on (^R)eloads.  Will be wrong if the document is actually a

  changing script output, or SSI with changes in the sizes of inserts,

  and any form entries will be lost with no warning about that if no

  form links are in the currently displayed page (and there may be other

  glitches I don't remember any more).  However, it's correct, and more

  convenient, most of the time, and nothing really bad will happen if

  it's wrong. - FM

03-05-96

* Added SAVE_SPACE configuration symbol in lynx.cfg, and LYNX_SAVE_SPACE

  environment variable (Unix) or logical (VMS) for setting a default path

  prefix in suggested filenames in Save to Disk operations of the 'p'rint

  and 'd'ownload menus.  If not set, only a filename will be suggested,

  for saving in the current default directory.  See the INSTALLATION file

  and lynx.cfg for more information. - FM

03-02-96

* If an IMG tag has both ISMAP and USEMAP attributes, create links for

  both, and use the ALT string, if present, for the USEMAP link.  The

  server-side script might have a content-rich default set up for non-GUI

  clients, so we may as well be able to try it, and still have our own

  USEMAP listing available if it's a site unconcerned about text and

  braille clients, or GUI clients with image loading turned off. - FM

* Tweaks of MAP code to maximize efficiency of fetching and processing

  MAPs from a different document. - FM

* Make sure the traversal code doesn't get tripped up by any HREFs

  which contain newline characters due to misparsing (e.g., because a

  close-double-quote wasn't present where required, and soft_dquotes

  wasn't toggled ON, or invalid comments were present, and mimimal or

  historical comment parsing weren't toggled ON). - FM

* Renamed LYK_RESUBMIT ('x' or 'X') to LYK_NOCACHE and modified it's code

  so that it applies to normal links as well as form submit buttons.  If

  used instead of LYK_ACTIVATE, any HText cache from a previous submission

  or request will be dumped, and the submission or request will be made

  with the  "Pragma: no-cache"  and  "Cache-Control: no-cache"  headers

  included, to ensure that a proxy/cache server also will not return a

  cached copy (assuming it respects either of those headers). - FM

03-01-96

* Converted the client-side image MAP code to a protocol which returns

  a stream, rather than using a temporary file.  This allows saving

  the link as a bookmark, for fetching the MAP and creating a listing

  without need to fetch and render the original document.  Also enabled

  direct downloading of the MAP listing. - FM

02-29-96

* Added handling of client-side image MAPs.  If both USEMAP and ISMAP

  attributes are present, the client-side MAP is used instead of the

  the server-side script.  The MAPs can be in the same or different

  documents.  The HREFs of the AREA tags are presented as a list,

  with their ALTs (if present, otherwise their HREFs) as the link names

  in the list.  Added a TITLE attribute for MAPs, which will be ignored

  by GUI clients, but if present will be used by Lynx as an H1 for the

  list (MAP NAME="welcomemap" TITLE="Welcome Map").  Otherwise, the

  IMG's ALT (if present, otherwise "[USEMAP]") will be used as an H1

  in the list.  The MAP's resolved URL also is shown in the list, since

  the URL for the list is a temporary file. - FM

02-25-96

* Added a MINIMAL_COMMENTS configuration symbol, which if set TRUE in

  lynx.cfg will emulate the Netscape v2.0 comment parsing bug of seeking

  only a '-->' terminator, and not interpreting '--' pairs as serial

  comments within the overall comment element.  The compilation default

  is FALSE, but we'll set it TRUE in lynx.cfg until Netscape gets its

  comment parsing right, and "decorative" dashes in comment elements

  cease to be so common in "Enhance for Netscape" pages.  Also added

  a '-minimal' command line switch for toggling the Mininal or Valid

  configuration setting, and an LYK_MINIMAL command key toggle (mapped

  by default to backquote).  Note that setting Historical comments on

  will override the Minimal or Valid setting (i.e., any '>' will be

  treated as the terminator of a comment element).  A statusline

  message indicates whether Historical, Minimal or Valid comment

  parsing has gone into effect when the LYK_MINIMAL or LYK_HISTORICAL

  command key toggles are used (i.e., those two toggles in effect are

  a "troggle"). - FM

02-22-96

* Tweak of HTList manipulations. - FM

* Additions to the online help. - FM

* Unescape any hex escaped username and/or password in ftp URLs. - FM

02-20-96

* Handle timeout disconnects of cached NNTP connections. - FM

* Allow head or tail match specifications (e.g., comp.infosystems.*

  or *.unix) in news, nntp and snews URLs (That's illegal, so don't

  use it in public documents.). - FM

* Tweak of bookmark handling. - Ismael Cordeiro (ismael@CAM.ORG)

02-16-96

* Tweak of the new code for setting a default CHECKED radio button. - FM

02-15-96

* Issue a sensible exit message if a non-http URL is used as the startfile

  with -traversal. - FM

* Tweaks of bookmark handling. - FM

* Tweaks of Home_Dir() type casting. - FM

02-14-96  Happy Valentine's Day!!!

* Tweaks of charset conversions. - FM

02-12-96

* Made inclusion of Unix DIRED_SUPPORT the compilation default, and

  its refinement easier to understand and set in the Makefile. - Will

  Mengarini (seldon@eskimo.com) & FM

* Changed (X) and ( ) to [X] and [ ] for indicating checked or unchecked

  checkboxes.  For radio buttons, we still use (*) and ( ). - FM

02-11-96

* Distinguish checkboxes from radio buttons in the Lynx display by using

  (X) versus (*), respectively, when they are checked or selected. - FM

* Make the first radio button in a series with the same NAME checked by

  default if none of them had CHECKED specified. - FM

02-09-96

* Added LYK_HISTORICAL and LYK_SOFT_DQUOTES, mapped by default to the

  the single- and double-quote keys, respectively, for toggling valid

  versus "historical" comment parsing, and valid versus "old Mosaic-

  and Netscape-like" double-quote parsing. - FM

* Added SCRIPT to the DTD and code to ensure that bad comments in its

  content don't generate garbage in the display. - FM

* Added -DSVR4 to the make for solaris2. - KH

* Use copy instead of rename in descrip.mms for putting lynx.exe in the

  top directory, as in build.com. - FM

* Added TITLE attribute to FORM, and code to use it for the Subject in

  mailto ACTIONs.  It's not in the spec, but better to offer it than

  to settle into Netscape's ?subject=foo tack-on kludge which breaks

  mailto for clients which haven't added code to cope with it. - FM

02-08-96

* Added -book switch for using the bookmark page as the startfile.  The

  default or command line startfile will still be set for the 'm'ain screen

  command, and be used as the startfile if the bookmark page is unavailable

  or blank. - FM

* Fixed glitch for Unix in yesterday's LYMail.c mods. - FM

* Try graceful alternatives if getenv("HOME") returns NULL. - Kenneth Herron

  (kherron@campus.mci.net) & FM

02-07-96

* Added support for the ?subject=foo tack-on kludge to specify the Subject

  in mailto ACTIONs and HREFs. - FM

* Convert Explorer's semi-colon Internet address separators to commas

  before acting on mailto address lists on Unix or VMS. - FM

* Made EMBED empty again (the W3C container version has been replaced

  by INSERT, and Netscape still has it empty). - FM

02-06-96

* Tweaks of descrip.mms files for VMS. - FM

02-04-96

* Fixed caching of news/nntp connections so that we access the correct host

  when more than one has been specified. - FM

02-03-96

* Added ndash and mdash to the entities conversion tables.  The W3C's

  DTD specifies those, whereas the text descriptions say endash and

  emdash, so we'll cover all the bases by supporting all four. - FM

* Reduced the "en" metric for TAB to 2 per column.  Was 12, to be

  compatible with UdiWWW, but that's pixels.  You can change the enval

  initialization in HTML.c from 2 to 12 if you want the old behavior. - FM

* Force use of DECC in build.com if that compiler is installed on VMS,

  and make sure external logicals don't defeat a choice of DECC via

  descrip.mms. - FM

02-02-96

* Mods to handle lone CRs as newlines when dislaying text/plain files

  from MAC servers.  Note that they'll stay CRs when downloading, or

  fetching with -source, but be handled as newlines when the '\' source

  toggle is used for text/html files and their source is displayed as

  text/plain. - FM

01-31-96

* Added dummy initializers in LYCharSets.c and LYEditmap.c to ensure the

  modules are linked if the external model is common block and they are

  placed in a library. - FM

01-30-96

* For submissions of forms with a mailto ACTION, allow the user to edit

  the default Subject string (the TITLE of the document containing the

  form) via a statusline prompt, or to cancel the submission via Ctrl-G

  at the prompt, analogously to 'c'omments or for anchors with a mailto

  HREF. - FM

01-29-96

* Typo fixes in HTML.c, LYJump.c and LYGetFile.c. - PM

01-28-96

* Tweaks of redirection handling. - FM

01-27-96

* Support use of the TITLE attribute for setting the Subject in LINKs with

  REV="made" or REV="owner" and a mailto HREF, equivalently to its use

  with anchors in the BODY. - FM

* Always use the parent document's URL for X-URL in mailto anchors, but

  still use mailto:address if it was entered as a 'g'oto. - FM

* Improvements of the code in LYMainLoop.c for checking the types of

  links (first make sure that there are links to check 8-). - FM

01-26-96

* Made LYCharSets.c an object module instead of header for HTML.c, and

  created LYCharUtils.c with character-related functions from HTML.c,

  to reduce the size of HTML.c (got a report of memory exhaustion when

  trying to compile HTML.c). - FM

* Added BGSOUND to the DTD and code for creating a link to the source

  when clickable_images is set. - FM

01-24-96

* Tweak of URL resolving when http servers return the obsolete file URL

  format for what are actually ftp URLs (as DEC's servers are doing). - FM

* Added LYE_LOWER and LYE_UPPER for lower or upper casing lines with the

  line editor.  Default bindings are Ctrl-K and Ctrl-T, respectively (not

  "intuitive" but they're the only "safe" non-printing keys left 8-). - FM

01-23-96

* Yet more tweaks aimed at getting Lynx to compile across versions of

  MultiNet through v3.5A and DECC through v5.2 or VAXC.  Pat Rankin

  is trying to cope with this mess for compilations with MultiNet and

  his VMS port of GNUC (cross your fingers 8-). - FM

* Updates of the help and about files. - FM

* Tweak of sendmail path for BSDI. - Bennett Todd (bet@ritz.mordor.com)

* More tweaks for dealing with header conflicts in MultiNet v3.5A with

  DECC v5.2. - FM

* Tweak of our kludge to append a 0,0 coordinate pair for ISMAP URLs. - FM

* Tweaks of base handling in HTML.c. - FM

01-20-96

* Mods for builds with NetBSD, or MultiNet v3.5A with DECC v5.2 (they

  have conficting headers). FM & PR

01-18-96

* Improved and corrected the fatal error messages. - FM

01-17-96

* Added ability to set the NNTPSERVER environment variable via lynx.cfg if

  it has not been set externally (analogously to the proxy variables). - FM

* Tweaks of proxy handling. - FM

* Modifed the "Accept-Language: " header handling so that is uses the

  "perferred document lang(G)uage" string without any modifications.

  This allows the user to specify a comma-separated string with quality

  values included, exactly to his/her requirements. - FM

01-16-96

* Modified the traversal code so that it always outputs to an error file if

  requests fail or unknown statuses are received from the http server. - FM

* Added target "sun4-ncurses" to the Makefile. - Bennett E. Todd

  (bet@nyc.fcmc.com)

* Tweaks of "preferred document lan(G)uage" and "preferred document c(H)arset"

  'o'ptions handling.  Send only the preferrence or comma-separated list of

  preferrences in the "Accept-Language: " and "Accept-Charset: " headers.

  Append ", en" if "en" isn't present, and ", ISO-8859-1" and/or ", US-ASCII"

  if those aren't present, rather than relying on servers to honor defaults,

  but still don't send an "Accept-Charset: " header at all if no preference

  has been specified by the user. - FM

* Fixed typos in the about and help files. - FM

01-15-96

* Tweaks of bold and underline setting in split_line() of GritText.c. - FM

* Fixed handling of FORM start tags with no ACTION specified. - FM

* Tweaks of "IBM PC character set" and added "IBM PC codepage 850"

  (ISO8859-1, see IBMPC-charsets.announce). - Mike Brown (mike@hyperreal.com)

* Check in userdefs.h whether LYNX_CGF_FILE has been defined via the

  Makefile, build.com or descrip.mms. - PG

* Created CHANGES2-3 with changes through release of Lynx2-3 on 04-19-94,

  and CHANGES2-4 with subsequent changes through the rename of lynx2-3-FM

  to Lynx2-4 and its release on 06-18-95, and deleted those sections from

  this file. - FM

* Added the new Copyright and links to it in about_lynx.html. - FM

01-11-96

* Tweaks of HTWAIS.c for compatibility across versions of FreeWAIS. - FM

* Unescape any hex escaped percents in mailto URLs and ACTIONs. - FM

01-10-96

* Added an LYCheckForProxyURL() function, and a PROXY_URL_TYPE return value

  for is_url(), so that Lynx can proxy URLs with an unknown scheme if a

  proxy for the scheme has been set, e.g., if "foo_proxy" has been set

  to "http://host/", then "foo:blah", where "blah" may or may not begin

  with a slash, will be handled as "http://host/foo:blah".  Components of

  "blah" will be checked versus "no_proxy", if set, but since we don't

  know the default port for scheme "foo", the checks for any ports

  associated with the no_proxy values may not be reliable (but if we

  don't proxy, nor know the scheme, nor find "foo:blah" as a local file,

  the URL would fail, anyway)  - FM

* Fixed typo in VMSPrint.com. - Paul Farnham (farnham@pasco.wednet.edu)

01-06-96

* Tweak of traversal code. - FM

01-04-96

* Tweak of dynamic SOCKS mods. - TZ

01-03-96

* Added circular recall buffers for JUMP shortcuts.  If multiple jumps

  files are installed, each has it's own recall buffer.  If Lynx was built

  with PERMIT_GOTO_FROM_JUMP defined, any random URLs accessed via the JUMP

  command are placed in the goto circular buffer, not that for shortcuts,

  and a JUMP entry of the single character ':' for the target is treated

  as a command to invoke the circular buffer of previously resolved goto

  URLs (as if 'g'oto followed by Up-Arrow were used). - FM

* Added GOTOBUFFER, homologous to JUMPBUFFER, for specifying via userdefs.h

  and/or lynx.cfg whether to offer the previous goto URL, if any, for

  reuse or editing whenever the 'g'oto command is entered, or simply rely

  on invoking the circular buffer via the Up-Arrow and Down-Arrow keys for

  accessing previously resolved goto URLs. - FM

* Tweak of 'g'oto recall buffering loop in LYMainLoop.c. - AH

01-02-96

* Added circular recall buffering for 'g'oto URLs.  Is invoked (if previous

  URLs have been entered) via Up-Arrow or Down-Arrow after entering the

  'g'oto command. - FM

* Added circular recall buffering for WHEREIS queries.  Buffer is shared with

  that for ISINDEX queries, and invoked via Up-Arrow or Down-Arrow following

  the WHEREIS ('/') command.  The 'n'ext command still uses the last WHEREIS

  query, not necessarily the last entry in the recall buffer, which might

  have been entered via a 's'earch command for an ISINDEX document. - FM

* Extended treatment of FORMs which have only one INPUT (TYPE="text") field

  for user entries as SUBMITting on press of RETURN in that field, so that

  this behavior is retained if INPUT TYPE="hidden" fields are present. - FM

* Tweaks of bookmark deletion sanity checks. - DT

01-01-96 (Happy New Year!!!!)

* Added circular recall buffer for ISINDEX queries.  Up-Arrow will cylce

  you from the most current query in the list to previous ones, and roll

  from the oldest to the most current.  Down-Arrow will cycle from the

  oldest query to subsequent ones, and roll from the most current to the

  oldest.  If a previous query is reused, it is removed from the recall

  buffer and reinserted as the most current.- FM

* Plugged memory leaks in LYUtils.c and LYJump.c. - FM

12-30-95

* Added LOCALHOST_ALIAS symbols for lynx.cfg which can be set to local

  host aliases or to trusted hosts at other sites which will be accepted

  as "local" when the -localhost switch is set. - FM

* Added the endash and emdash entities. - FM

12-29-95

* Use exit(0) versus exit(-1) more consistently for normal versus abnormal

  exits, respectively. - FM

12-26-95

* Tweak of RELOAD handling for lynxcgi URLs. - FM

* More anti-crash protections for bad HTML. - FM

* Tweak of dynamic SOCKS mods. - TZ

12-23-95

* Tweaks of directory building on VMS. - FM

* Tweaks of log file declarations for direct wais builds. - FM

* Tweak of DIRED_SUPPORT mods so that non-TAG entries don't show up when

  there are tagged files. - DT

12-22-95

* Added HTMake_VMS_name() to HTFTP.c for use by Unix as well as VMS with

  VMS ftp servers. - FM

* Added INSERT and ALIAS to the DTD, updated PARAM and OVERLAY, and made

  FIG a paragraphing block, all as described in the 12-21-95 W3C working

  draft for INSERT.  In contrast to FIG, the INSERT and "heritage" EMBED

  and APPLET elements invoke paragraphing only if their content displayed

  by Lynx dictates it.  The rules for resolving the sources for INSERTs or

  for handling its ISMAP attribute are extremely complicated, and are not

  implemented.  Let's wait to see how people in the "real world" try to

  make sense of them and actually use INSERT (if they do 8-).  We still

  create source links in "clickable_image" mode for the "heritage" versions

  of FIG, OVERLAY, EMBED and APPLET markup, and send a 0,0 cooridinate pair

  for IMG with the ISMAP attribute.  See comments in HTML.c - FM

12-21-95

* Fixed bug in yesterday's ftp password-handling mods that could cause a

  crash, and handle ftp://user:@host/path as specified in RFC 1738. - FM

* Added protection against crashes for SELECT tags without the (required)

  NAME attribute. - FM

* Added code in HTFTP.c for recognizing MS Windows (Chameleon NEWT) servers

  and parsing their LIST output (tested on ftp://emoryi.jpl.nasa.gov/) - FM

* Another typo fix for VMS GNUC in HTFinger.c. - FM

* Modified HTFTP.c to use personal_mail_address, if available, for the

  password with anoymous FTP.  It will still use "user@" (trim off the

  host) if the host does not contain a dot and thus could not be a fully

  qualified domain name, so it will work with Unix servers such as

  ftp.uu.net (see get_connection() in HTFTP.c), but this will cause it

  to fail with MS Windows servers. - FM

* Added lots more info to the trace output for the ftp gateway. - FM

12-20-95

* Modified HTFTP.c to handle a hex escaped slash (%2F) following the

  "punctuation" slash according to the strict provisions of RFC 1738

  when connected to VMS ftp servers, so that a device can be in the

  path and not be mishandled as a subdirectory, e.g., the URL

     ftp://user:password@host/%2Fsys$common/syshlp

  will create a directory listing for sys$common:[syshlp]. - FM

* Fixed typo for VMS GNUC in HTFinger.c. - FM

12-19-95

* Enhancements of Unix DIRED_SUPPORT (see header of LYLocal.c). - DT

12-18-95

* Tweaks of element and entity structure alignments. - FM

12-17-95

* Tweaks of APPLET CODEBASE attribute resolving. - FM

* Added support for a -nosocks command line switch to turn off SOCKS proxy

  usage if Lynx was SOCKSified. - Thomas Zerucha (tz@execpc.com)

12-16-95

* Added the APPLET element and attributes to the DTD, and code for

  creating links to the Applet code via image_links - FM

* Added code to handle password fields in telnet URLs. - FM

* Expanded EMBED as an "attribute soup" (for compatibility with

  old versions of Netscape). - FM

12-15-95

* Added PARAM, and its attributes in the W3C draft for EMBED, to the DTD,

  and code in HTML.c to minimize the possiblity of an INPUT belonging to

  an EMBED being misassociated with a standard FORM container. - FM

* Added "first pass" EMBED handling.  Should be OK with both the W3C

  container version and the Netscape "attribute soup" version (we'll

  see 8-).  The clickable_image switch and toggle ('*') are now misnomers.

  They will cause creation of links to the EMBED SRCs whether they are

  images or not. - FM

* Enhancements of Unix uploading (see header of LYUpload.c). - GL

12-14-95

* Modified LYUnEscapeEntities() and LYExpandString() in HTML.c to make

  it more likely that they'll be handled correctly across flavors of

  compilers. - FM

* Changed NETSCAPE_QUOTES and -netscape_quotes to SOFT_DQUOTES and

  -soft_dquotes. - FM

* Added '&' to the exclusion list for VMS suggested file names. - FM

12-13-95

* Added CAN_ANONYMOUS_GOTO_TELNET_PORT symbol which if set TRUE in

  userdefs.h will allow anonymous users to specify a port in 'g'oto

  commands for telnet URLs. - FM

* Added NETSCAPE_QUOTES symbol which if set TRUE in lynx.cfg will cause

  Lynx to emulate the Netscape bug of treating  '>' as a co-terminator

  of a double-quoted attribute value and the tag which contains it. - FM

* Forgot to define FORM_LINK_RESUBMIT_MESSAGE in the distribution's

  userdefs.h for yesterday's mods. - FM

* Forgot to put the HTFile.c with the LIST_FORMAT mods into the

  distribution (maybe I should just concentrate on Christmas 8-). - FM

12-12-95

* Changed handling of the no-cache META directive so that it applies to

  the document which contains the META tag, rather than to any form submit

  buttons within it.  The form's CGI script should return a stream which

  contains the directive to force resubmissions, and any (e.g., ISINDEX)

  script or (e.g., foo.shtml) document can include the directive to

  force reloading by Lynx. - FM

* Added ALWAYS_RESUBMIT_FORMS symbol in userdefs.h and lynx.cfg for setting

  forced resubmissions of forms, and a -resubmit_forms command line switch

  for toggling the default. - FM

12-11-95

* Moved values of LYStrings.h function key definitions from 0x80 - 0x8D to

  0x100 - 0x10D and modified all the structures and functions in LYKeymap.c

  and LYEditmap.c accordingly. - FM

* Added the KOI8-R (Russian) character set. - Andrey A. Chernov

  (ache@astral.msk.su).

* Replace gets() with fgets() for the Unix setup() in LYCurses.c - AAC

* Tweaks for building with FreeBSD. - AAC & FM

* Added handling of META directives for ISO-8859-2 and KOI8-R if the

  document is text/html and a server header didn't already set the

  charset. - AAC & FM

12-10-95

* Tweaks of memory management. - FM

* Made the LONG_LIST parameters for Unix local directory listings

  configurable via userdefs.h and lynx.cfg - DT

12-09-95

* Added code for re-computing and retaining the current link if it is still

  on the page when using the LYK_UP_TWO and LYK_DOWN_TWO commands. - FM

* Added support for nested emphasis tags (they're all still displayed as

  HT_UNDERLINE, but no longer terminated prematurely). - FM

12-08-95

* Added more suffix maps in HTInit.c. - FM

* Tweak of META attribute definitions. - FM

12-06-95

* Don't reject LYNXKEYMAP and lynxcgi URLs with the -localhost switch. - FM

12-05-95

* Made the loaded_texts list in GridText.c functionally "circular", so

  that returning to a cached document causes it to be treated as the most

  current, and dumps of cache, when necessary to load a new document, are

  done for the least recently viewed rather than least recently fetched

  document. - FM

* Show the METHOD and ACTION in showinfo() of LYShowInfo.c if invoked when

  the cursor is positioned on a submit button. - FM

* If the user mode is advanced, keep showing the URL in the statusline

  when Lynx is in forms mode but the link is not a form field. - FM

12-03-95

* Tweaks of code for submissions of forms with only a single INPUT

  (TYPE="text") field. - FM

12-02-95

* Treat any META directives with a NAME or HTTP-EQUIV value of "Pragma"

  or "Cache-Control" and a CONTROL value of "no-cache" as an instruction

  always to resubmit any form(s) in the document. - FM

* Added parsing of META directives.  Functions can be added where indicated

  in HTML.c. - FM

* Include the HTTP/1.1 "Cache-Control: no-cache" header together with the

  HTTP/1.0 "Pragma: no-cache" header for reload or resubmit requests. - FM

* Fixed bug in the check for an all-space ALT in IMG when creating a

  link for its SRC. - FM

* Fixed parsing of square-bracketted DOCTYPE fields. - FM

12-01-95

* Improvments of logic for indentations within lists. - FM

11-30-95

* For resiliency, treat upper case letters as equivalent to lower case in

  scheme names (e.g., allow "HTTP" as well as "http"), by converting them

  to the appropriate case before entering them into the anchor hash table

  or otherwise acting on them. - FM

* Added ability to change the default reply to the "really quit" prompt

  from "[Y]" to "[N]" via a compilation symbol in userdefs.h. - DT

11-29-95

* Added ALIGN attribute for HR (default is "center"). - FM

11-28-95

* If a form has a single field, and it's INPUT TYPE="text", treat

  RETURN as a submit command for it. - FM

* Added START as a synonym for the SEQNUM attribute in OL. - FM

11-27-95

* Enhancements of the wais gateway. - FM

11-26-95

* Fixed up HREF, ACTION and SRC resolving to be conformant with RFC 1808

  (except that we don't yet support a ";params" field). - FM

11-25-95

* Tweaks of yesterday's jumps file mods. - FM

11-24-95

* Enhancements of 'J'umps file handling, including ability to install

  multiple jumps files mapped to different keys and associated with

  different statusline prompts and recall buffers. - DT & FM

* Deal with ALTs that have only spaces when in clickable_image mode. - FM

* Worked in WM's mods to make the REVERSE_CLEAR_SCREEN_PROBLEM workaround

  a configuration option via ENABLE_SCROLLBACK in lynx.cfg and a command

  line toggle (-enable_scrollback), for use with comm programs which have

  screen display buffers that can be accessed for review independently

  of the Lynx commands (see comments in lynx.cfg). - FM

11-23-95

* Use the BASE, if present, instead of the original document URL, as the

  default ACTION for forms. - FM

* Tweaks of paragraph alignment handling. - FM

* Make sure we don't realloc() a NULL env pointer in LYCgi.c. - DT

* Cancel bookmark deletion if the line does not have a complete link or if

  there is more than one link on the line. - DT

11-21-95

* Fixed bad logic in the setting of bold and/or underline starting points

  in new lines created via split_line() of GridText.c. - FM

* Added case KEY_BACKSPACE in LYgetch() of LYStrings.c. - GL

11-19-95

* Fixed problem of SELECT causing all immediately following white space

  to be ignored. - FM

* More tweaks of paragraphing, and handling of labeled blocks within

  PRE blocks. - FM

11-18-95

* Added INFOSECS, MESSAGESECS and ALERTSECS symbols in userdefs.h and

  lynx.cfg for setting the durations of statusline pauses (important when

  using Lynx with a braille-based access).  See comments in userdefs.h and

  lynx.cfg for more information. - FM

* More tweaks of paragraph handling. - FM

* Include the Reference lists is crawl output files if the -number_links

  switch was included and the -nolist switch wasn't. - FM

11-17-95

* Tweaks of finger and telnet gateways. - FM

* Added handling of MARQUEE equivalently to BANNER. - FM

* Various tweaks of 8-bit character and related HTML handling (OLs

  or ULs without attributes or some wrong combinations were crashing

  Lynx). - FM

11-16-95

* Implemented the ID attribute for TAB, and the TO and INDENT attributes

  when its ALIGN attribute is "left" (the default) and the style's

  alignment is HT_LEFT (the default).  If these conditions don't apply,

  or if the TAB target is outside the current margins or would overlap

  prior text, a collapsible space is inserted instead of TABing.  The

  INDENT values are in "en" units, treated as 12 per column.  Added

  tabtest.html in the test subdirectory to illustrate TABing. - FM

11-15-95

* Added the HTML 3.0 DTD structures and definitions for SPOT, and fully

  implemented it (use SPOT ID="foo" as SGML_EMPTY instead of named anchors

  with no content). - FM

* Added the HTML 3.0 DTD structures and definitions for TAB.  For now, it

  simply puts a collapsible space in the text stream if the TO attribute

  is present. - FM

* Added the top-level HTML 3.0 DTD structures and definitions for MATH, and

  implemented it's ID attribute.  The markup is captured as HTML_LITTERAL,

  and until we have a processor, is output as is, in brackets to alert the

  user about the situation. - FM

11-14-95

* Tweaks of LYK_UP_LINK and LYK_DOWN_LINK handling, and added them to the

  default mapping as '<' and '>'. - FM

* Tweaks of LYK_TOOLBAR handling. - FM

11-13-95

* Added LYK_TOOLBAR (mapped by default to '#') for jumping up to the pseudo

  Toolbar or Banner if present in the current document.  Using '#' instead

  of Home to jump there allows you to Left-Arrow back to where you were in

  the current document.  Set up a BANNER in about_lynx-dev.html to serve

  as an example of this feature. - FM

* Added the HTML 3.0 DTD structures and definitions for BANNER, implemented

  its ID attribute, and set it up to act as a pseudo Toolbar if one hasn't

  been set up already via REL attributes of LINKs. - FM

* Tweaks of paragraphing for CAPTION, CREDIT, FOOTNOTE, and NOTE. - FM

11-12-95

* Handle (i.e., ignore) any P that immediately follows an LI, DT or DD. - FM

* Cancel any file fetch and viewer spawn or launch during traverals. - FM

11-11-95

* Added finger gateway (finger://host[/request]) based on patches from

  Martin Hamilton (martin@mrrl.lut.ac.uk). - FM

* Added LYE_TAB for mapping keys to act as LYE_ENTER, but return '\t' so

  that the behavior of TAB is emulated in TEXTAREAs, and mapped Do to

  LYE_TAB in the default binding. - FM

* Fixed glitch in handling of DEC extended characters which contain two

  digits (affected Do and Find). - FM

* Better documented that disabling access to hidden (dot) files also

  disables ability to create such files via Lynx. - FM

11-10-95

* Added handling of mailto as a form ACTION.  See http://www.q-d.com/swc.htm

  for software to extract and unescape the mailed content. - FM

* Added lynxprog URL handling, which is identical to lynxexec URL handling

  except that the user is not prompted to enter RETURN before returning

  to Lynx.  Use lynxprog for scripts or programs such as mail which do not

  need an enforced pause to let the user read the screen output. - FM

* Removed code in HTFile.c for treating ',' as a synomym of '.' for

  hidden files (nobody seems to know why that was being done 8-). - FM

* Moved inclusions from LYBookmark to tcp.h. - FM

11-08-95

* Extend optional hidden (dot) file/directory support to Unix, and embellished

  it on VMS and Unix with regulation via a command line switch and 'o'ptions

  menu setting.  See userdefs.h and lynx.cfg for more information. - GL & FM

* Added support on Unix for straight tar files and a compile time option that

  disables the ability to extract files from an archive file (since there is

  no control over the files extracted). - GL

11-07-95

* More tweaks of 8-bit character handling. - FM

* Added "Macintosh (8 bit)" character set. - Neil K. Guy

  (nkg@freenet.vancouver.bc.ca)

* Added "Example Lynx Optimized User Home Page" to the online 'h'elp. - FM

11-05-95

* Fixed Cc: header handling for email on Unix. - FM

11-04-95

* Reference the current character set for any raw 8-bit characters in

  text/plain streams (but don't translate named or decimal escaped

  entities, since that's specific for text/html). - FM

* Block any illegal control or escape characters in text/plain streams,

  to avoid problems if a binary ftp or local file was mistyped and sent

  to the screen as that Content-type. - FM

* Eliminated mod in SGML.c which emulated Netscape's bug of treating '>'

  as both a close-double-quote and close-tag (Netscape v2.0 fixed its

  bug, so hopefully the bad HTML with it will go away. 8-). - FM

11-02-95

* Assume an ISO-8859-1 character set for all local files.  If it's

  actually ISO-8859-2 and the terminal is using that, set the Lynx

  CharSet option to "ISO Latin 1" so that 8-bit characters will be
