# Change Log

## v0.9.0 - 2018-05-08

### Added:

- amqp-publish: added support for specifying headers via the -H flag

- Add support for specifying timeout for amqp_login calls via

  amqp_set_handshake_timeout

- Add support for specifying timeouts in RPC-style AMQP methods via

  amqp_set_rpc_timeout

- Add define for `AMQP_DEFAULT_VHOST`

- Support for SSL SNI

- Support for OpenSSL v1.1.0

### Changed:

- rabbitmq-c now requires Windows Vista or better

- rabbitmq-c enables TCP keep-alive by default on platforms that support it

- dropped support for compiling rabbitmq-c without threading support

- OpenSSL is no longer un-intialized automatically by default. OpenSSL can be

  explicitly initialized by calling amqp_initialize_ssl_library and

  uninitialized by calling amqp_uninitialize_ssl_library.

### Fixed:

- Correct bugs in processing of --url flag in tools (#364).

- Improve documentation on AMQP_SASL_METHOD_EXTERNAL (#349)

- Improve support for compiling under mingw-w64

- Better support for handing SIGPIPE on Linux over SSL (#401)

- Improve publish performance on Linux by not specifying MSG_MORE on last part

  of message.

- Fix connection logic where multiple hostnames won't be tried if connection to

  doesn't fail immediately (#430)

### Removed:

- autotools build system has been removed

- many duplicate amqps_* examples, they did not add a lot of value

## v0.8.0 - 2016-04-09

### Added:

- SSL: peer certificate and hostname validation can now be controlled separately

  using `amqp_ssl_socket_set_verify_peer` and

  `amqp_ssl_socket_set_verify_hostname`.

- SSL: the desire SSL version range can now be specified using the

  `amqp_ssl_socket_set_ssl_versions` function.

- Add flags to SSL examples on controlling hostname verification.

### Changed:

- SSL: SSLv2, and SSLv3 have been disabled by default.

- SSL: OpenSSL hostname validation has been improved.

- Win32 debug information is built with /Z7 on MSVC to embed debug info instead

  of using a .pdb

### Fixed:

- Connection failure results in hang on Win32 (#297, #346)

- Rabbitmq-c may block when attempting to close an SSL socket (#313)

- amqp_parse_url does not correctly initialize default parameters (#319)

- x509 objects are leaked in verify_hostname (#323)

- TCP_NOPUSH doesn't work under cygwin (#335)

### Deprecated

- SSL: `amqp_ssl_socket_set_verify` is being replaced by

  `amqp_ssl_socket_set_verify_peer` and `amqp_ssl_socket_set_verify_hostname`.

### Removed:

- OpenVMS build system and related files.

- Unmaintained PolarSSL, CyaSSL, and gnuTLS SSL backends
