0.5.2 (2015-11-23)

• Fix META file for versions of OCaml older than 4.02.0 (thanks Anil Madhavapeddy, closes #20).

0.5.0 (2015-05-18)

• Allow to honor server cipher preferences (thanks mfp, closes #18).

• Add functions for reading into/writing from bigarrays, avoiding copy (thanks mfp, closes #15).

• Support disabling SSL protocol versions (thanks Edwin Török, closes #13).

• Use Bytes instead of String for read and write, changes the ABI thus the version bump (thanks Vincent Bernardoff, closes #16, and mfp, closes #19).

• Make verbosity of client_verify_callback configurable (thanks Nicolas Trangez, closes #12).

• Fix double leave of blocking section in ocaml_ssl_accept (thanks Edwin Török).

• Check for errors in SSL_connect/SSL_accept (thanks Jérôme Vouillon).

0.4.6 (2011-10-16)

• Added write_certificate function.

• Remove support for SSLv2, which was dropped upstream (thanks Dario Teixeira).

• Use pthread mutexes for locking thread-safe version of ssl.

0.4.4 (2010-01-06)

• Use SSL_CTX_use_certificate_chain_file instead of SSL_CTX_use_certificate_file.

• Added support for --enable-debugging configure option.

• Don't link with unix library and don't build in custom mode.

0.4.3 (2008-12-18)

• Don't use blocking sections in finalizers since it causes segfaults (thanks Grégoire Henry and Stéphane Glondu).

0.4.2 (2007-03-29)

• Added some missing blocking sections (reported by Oscar Hellström).

0.4.1 (2007-02-21)

• file_descr_of_socket is not marked as deprecated anymore.

• Patched the Makefile to be compatible with FreeBSD (thanks Jaap Boender).

• Explicitely link with libcrypto since we use it. Compilation should now work on Mac OS X too (thanks Janne Hellsten).

0.4.0 (2006-09-09)

• Using caml_alloc_custom and Data_custom_val to access custom blocks.

• Added set_password_callback function.

• Integrated a big patch from Chris Waterson:

• Added get_error_string function.

• Read and write are not blocking anymore, use Unix.select and file_descr_of_socket if you want blocking functions.

• Fix SSL_CTX initialization to call SSL_CTX_set_mode(3) with SSL_MODE_AUTO_RETRY flag. This causes SSL_read and SSL_write to "hide" the SSL_ERROR_WANT_(READ|WRITE) errors that may occur during renegotiation on a blocking socket.

• Fix SSL_CTX initialization to call SSL_CTX_set_mode(3) with SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER flag. This allows for a different buffer address to be passed to a restarted non-blocking write operation, which is useful since the OCaml garbage collector may move buffers around between calls.

• We do not need to store explicitely the file descriptor for SSL sockets.

• Corrected checking of errors in ocaml_ssl_read (thanks Vincent Balat and Nataliya Guts).

• input_char now raises End_of_file when no byte could be read (thanks Nataliya Guts).

0.3.1 (2005-07-21)

• The library is now under the LGPL licence + linking exception + linking with openssl exception (see COPYING for more details).

0.3.0 (2005-06-01)

• Added Ssl_threads.init function to make the library thread-safe.

• Put connect, accept and flush (and all other functions) in blocking_section to allow other threads to run in the meantime.

• Unified the three context creation functions in create_context, the certificate to use should now be sepcified with use_certificate (sorry for the API-breakage).

• Added the get_verify_result function.

• Using Store_field instead of Field(...) = ...

• Using caml namespace functions.

0.2.0 (2004-12-18)

• Many thanks to Thomas Fischbacher for his patches:

• Corrected int / val bugs when raising exceptions from C (those where found by Mike Furr too, thanks).

• Added many fonctions (but in Caml instead of C).

• Context creation functions now take the protocol as argument.

• Added the create_context function (for client and server connections).

• Added functions for verifying certificates: client_verify_callback, set_verify, set_verify_depth, verify.

• The cipher now has its own type.

• Added functions to handle ciphers: get_current_cipher, get_cipher_description, get_cipher_name, get_cipher_version, set_cipher_list.

• Added the read_certificate and load_verify_locations functions.

• Added the open_connection_with_context and flush functions.

• read and write functions are now thread-safe.

• Cleaned the stubs (function prototypes, comments, etc.).

• Updated OCamlMakefile and improved build system.

0.1.0 (2004-02-05)

• Initial release.
