Changes in 3.2.3:

• fix issue when using ccphs (#116)

Changes in 3.2.2:

• Manage line length in generated files [GH-84]
• Fix issue when identifier with multiple single quotes, e.g. foo'' was used
• Allow omitting spaces around = in macro definitions
• Include pre-generated Parser.hs and Scan.hs in the Hackage upload, to make bootstrapping easier.

Changes in 3.2.1:

• Fix build problem with GHC; add new test tokens_scan_user.x

Changes in 3.2.0:

• Allow the token type and productions to be overloaded, and add new directives: %token, %typeclass, %action. See "Type Signatures and Typeclasses" in the manual.
• Some small space leak fixes

Changes in 3.1.7:

• Add support for %encoding directive (allows to control --latin1 from inside Alex scripts)
• Make code forward-compatible with in-progress proposals
• Suppress more warnings

Changes in 3.1.6:

• sdist for 3.1.5 was mis-generated, causing it to ask for Happy when building.

Changes in 3.1.5:

• Generate less warning-laden code, and suppress other warnings.
• Bug fixes.

Changes in 3.1.4:

• Add Applicative/Functor instances for GHC 7.10

Changes in 3.1.3:

• Fix for clang (XCode 5)

Changes in 3.1.2:

• Add missing file to extra-source-files

Changes in 3.1.1:

• Bug fixes (#24, #30, #31, #32)

Changes in 3.1.0:

• necessary changes to work with GHC 7.8.1

Changes in 3.0 (since 2.3.5)

• Unicode support (contributed mostly by Jean-Philippe Bernardy, with help from Alan Zimmerman).

• An Alex lexer now takes a UTF-8 encoded byte sequence as input (see Section 5.1, “Unicode and UTF-8”. If you are using the "basic" wrapper or one of the other wrappers that takes a Haskell String as input, the string is automatically encoded into UTF-8 by Alex. If your input is a ByteString, you are responsible for ensuring that the input is UTF-8 encoded. The old 8-bit behaviour is still available via the --latin1 option.

• Alex source files are assumed to be in UTF-8, like Haskell source files. The lexer specification can use Unicode characters and ranges.

• alexGetChar is renamed to alexGetByte in the generated code.

• There is a new option, --latin1, that restores the old behaviour.

• Alex now does DFA minimization, which helps to reduce the size of the generated tables, especially for lexers that use Unicode.
