spdylay 0.3.5
=============

Release Note
------------

This release fixes the bug that shrpx tries to read response body when
HTTP status code is 304 and nonzero Content-Length is returned.  The
SPDY client and server programs, spdycat, spdyd and shrpx, were moved
to src directory. The --enable-src configure option was added to
enable/disable to build them. In Python API, Session.resume_data() now
returns boolean value to indicate error instead of raising
InvalidArgumentError.

This release was made because the previous release, 0.3.4, did not
update library version. Other than updated library version number,
anything has not been changed since 0.3.4.

Changes
-------

* shrpx: Check request_connection_close_ when deciding closing
  connection.  When deciding whether to close the client connection,
  check request_connection_close_ of Downstream in addition of
  response_connection_close_. Also we only add "Connection:
  Keep-Alive" header to the HTTP/1.0 or HTTP/0.9 clients.

* python: Don't raise exception from Session.resume_data().  In
  practice, Session.resume_data() will be used without checking there
  is deferred data or not. Actually, there is no API to check this.
  So it is better not to raise exception. Instead return False to
  notify error. If the method succeeds, it returns True.

* Add --enable-src configure option.  When --enable-src is given, the
  programs in src directory will be built. If --disable-src is given,
  those programs will not be built. If none of them are given,
  --enable-src is assumed.

* Move spdycat, spdyd and shrpx from examples to src.  To distinguish
  the to-be-installed programs and non-installable example source
  code, the former programs, spdycat, spdydyd and shrpx, were moved to
  src directory. spdynative was removed from Makefile because it does
  not appeal to any users much.

* shrpx: Ignore response body if HTTP status code is 1xx, 204 or 304.

spdylay 0.3.3
=============

Release Note
------------

This release fixes the segmentation fault error if the name/value
pairs which include empty string name are passed as nv argument to
spdylay_submit_* functions. Spdycat gets new option to specify
arbitrary headers from command line. Shrpx gets new option to specify
allowed cipher list. Python wrapper python-spdylay was added.

Changes
-------

* Add spdylay_npn_get_proto_list() public API function.
  spdylay_npn_get_proto_list() returns a pointer to the supported SPDY
  version list. The element of the list is spdylay_npn_proto
  struct. It contains all SPDY version information this library
  supports. The application can use this information to configure NPN
  protocol offerings/selection.

* Add --enable-example configure option. If --disable-example is used,
  example programs will not be compiled.

* Fix error with w64-mingw32 cross compiler.

* Remove unused zlib.h header file from spdylay.h

* Fix segmentation fault error if the name/value pairs which include
  empty string name are passed as nv argument to spdylay_submit_*
  functions.

* spdycat: Adding arbitrary headers form the command line. Patch from
  Stephen Ludin.

* Fix intptr_t check in configure.ac. Patch from Stephen Ludin.

* shrpx: add --ciphers option to specify allowed cipher list

* python: Add Python wrapper for spdylay. It is released separately as
  python-spdylay package from PyPI.



spdylay 0.3.2
=============

Release Note
------------

This release adds many features and options to shrpx, HTTPS/SPDY
reverse proxy. Secure SPDY proxy mode was added to shrpx. Spdycat now
supports SNI, thanks to the patch contributed by Piotr Sikora.

Changes
-------

* spdycat: Add support for Server Name Indication (SNI). Patch from
  Piotr Sikora.

* spdycat: Use TLSv1_client_method

* shrpx: Add many new command-line options. It also now supports
  configuration file. Use http-parser instead of htparse. Add SPDY
  proxy mode.

* lib: Take into account shut_flags when accepting DATA frame.



spdylay 0.3.1
=============

Release Note
------------

This release fixes the bug that on_ctrl_recv_callback is not called
when RST_STREAM is received.  It also fixes the bug that
on_data_recv_callback and on_data_chunk_recv_callback is called after
the stream was closed. A multi-threaded reverse proxy for SPDY/HTTPS
is added as an example program.

Changes
-------

* Added --enable-maintainer-mode configure option If it is enabled,
  turn on extra compiler warnings.

* Don't call on_data_recv_callback and on_data_chunk_recv_callback if
  stream was closed or being closed.

* Added example program Shrpx: a multi-threaded reverse proxy for
  SPDY/HTTPS.  It accepts SPDY/HTTPS connections and converts them to
  normal HTTP and forwards to the downstream servers.

* Fixed bug on_ctrl_recv_callback not called for RST_STREAM

* Return nonzero exit status if test fails. Fixed failmalloc tests.



spdylay 0.3.0
=============

Release Note
------------

This release fixes buffer overrun when a lot of streams are created.
SPDYLAY_OPT_MAX_RECV_CTRL_FRAME_BUFFER option was added to control the
maximum payload size of the incoming control frames.

Changes
-------

* Bump up LT version to 2.0.1.

* Included <functional> from spdy.h

* Made spdylay_strerror(0) return "Success"

* Added SPDYLAY_OPT_MAX_RECV_CTRL_FRAME_BUFFER option.  This option
  sets maximum receive buffer size for incoming control frame.
  Basically the library checks the length field of the incoming
  control frame. For frames with name/value header block, the library
  also checks the length of inflated block is also under the
  limit. This is done while incrementally inflating block. If the
  length of frames with name/value header block exceeds the limit, the
  library will issue RST_STREAM with FRAME_TOO_LARGE. For other
  frames, it will issue GOAWAY.

* Incremental name/value block decompression

* Fixed buffer overrun in spdylay_pq_push
