This release in short

  LUA: Now Vortex Library officially support Lua through LuaVortex
  binding. See documentation to get ready building Lua BEEP


  SERVER SIDE: Added support for automatic thread pool resize, through
  vortex_thread_pool_setup, which allows a BEEP vortex peer to react
  to working peaks adding threads, reducing them automatically when
  working load decreases.

  SECURITY: added support to limit frame size that could be received
  when automatic frame joining is enabled.

  CODE MORE ROBUST: now frame objects acquire a reference to the
  context to allow them to live after a vortex context was
  finished. Updated vortex profiles module to support changing profile
  settings in a thread safe manner (including removing registered
Change notifications

  - vortex-conn-opts-01

  - vortex-ctx-data-01

Thanks to..

  - Ralf Konusch (Reported thread safety problems at vortex profiles
    module, reported and fixed problems at reg tests when TLS and SASL
    aren't available, reported problems with CONN_OPTS due to
    __VA_ARGS__ in Microsoft Visual Studio)

  - Dwnam (Reported inconsistencies at vortex ctx data API which
    caused vortex-ctx-data-01 change notify).

  - Dexter (Reported missing notify actions on TLS module when used in
    conjunction with PULL API).

  - Scott Zhang (Reported and fixed problems with headers at xml-rpc
    module and xml-rpc-gen tool when used with c++ compilers).

Changes since 1.1.9

* [fix] Updated API for vortex_set_data_full, vortex_ctx_set_data and
  vortex_ctx_get_data to make the key parameter to be const char *
  instead of axlPointer which is consistent with current implementation
  and avoid problems while passing other types (specially numbers or
  pointers) when a string it is in fact expected.

* [fix] Updated vortex frame module to acquire a reference to the
  VortexCtx to allow using frame references even after vortex ctx is
  finalized. This will simplify bindings..

* [fix] Setting close on exec flag on file descriptors created by

* [fix] Fixed leak inside channel start handling when an error reply
  is generated with a custom user message.

* [fix] Making channel start reply handling to remove the channel
  in case of error instead of waiting for the connection to finish.

* [fix] Replaced several calls to axl_free with vortex_frame_unref
  inside __vortex_frame_get_next.

* [fix] Added missing cleanup functions inside vortex tls module.

* [fix] Removed deallocation of ssl contexts (inside vortex tls) when
  a certificate failure is found (those objects are already removed by
  connection finish handlers).

* [fix] Updated regression tests to allow selecting the set of tests
  to execute.

* [fix] Nullified queue reference at pull API module (ctx was holding
  a reference to a deallocated queue).

* [fix] Fixed wrong memory access inside vortex listener regression

* [fix] Fixed PyVortex handling to detect pvalue == NULL after calling
  PyErr_Fetch, so it points to Py_None.

* [fix] Added a debug log into vortex_thread_pool.c code...

* [fix] Removed wrong PyVortex documentation reference (set_serialize)
  from vortex.Ctx .

* [new] Added initial support for automatic thread pool resizing,
  allowing a server to adapt its thread pool adding/removing working
  workers according to working peaks. API added:

    - vortex_thread_pool_setup

  Added regression test to check its function (test-00-c1).

* [fix] More updates to regression test (test-00-c1).

* [fix] Making vortex thread pool automatic resize to not have to
  release locks to add or remove thread from the pool to avoid races
  with the state and the number of threads added.

* [fix] Updating version files..

* [fix] Making vortex sequencer to acquire a reference to the vortex
  ctx and to release it when stop beacon is detected. Solves possible
  race condition when sequencer loop takes longer than 60 seconds stop
  during a call to vortex_exit_ctx.

* [fix] Reorganizing debian package files..

* [fix] Removed call to COMP_zlib_cleanup which seems to
  be not available in older distributions..

* [fix] Updating debian files..

* [fix] Adding change notification vortex-ctx-data-01.txt and fixed
  manual type (Reported by Dwnam).

* [fix] Updated vortex profiles module to implement reference counting
  internally which allows to unregister profiles at run time. Also
  updated the module to acquire references to handlers and data to
  make the check and the execution to play with the same references
  (avoid races).  Also fixes when a frame received was unset from a
  profile during a heavy load frame received call (Reported by Ralf

* [fix] Making vortex channel send operations to check result from
  vortex_channel_ref before configuring vortex payload feeder.

* [fix] Added regression test test_01-v to check support for dynamic
  profile unregistering. Also fixed channel close request to always
  accept in the case no handler is found and the profile is not

* [new] Added support to limit max incoming message size when complete
  frame flag is enabled. Updated documentation to explain security
  risks (vortex_channel_set_complete_flag). Added regression test
  test-01w to check support added. API added:

   - vortex_channel_set_complete_frame_limit

* [fix] Applied some changes to disable TLS and SASL reg tests when
  these components aren't available. Fixed variable declaration after
  code inside vortex profiles module. (Fixed and reported by Ralf

* [fix] Fixed possible race at vortex sequencer that may provide
  access to a channel reference inside a connection that is not

* [fix] Updated vortex connection actions notify to be reetrant
  (required for auto tls and fix introduced by test-14-h).

* [fix] Fixed vortex tls module which wasn't creating notify actions
  for TLS connection created. This was also causing problems at the
  PULL api because connection close event was not triggered for TLS
  connections (Reported by Dexter). Added regtest test-14-h to
  reproduce the bug and check fix introduced.

* [fix] Updated documentation to explain what happens with content
  configured with vortex_connection_set_data during a tls activation..

* [fix] Fixed xml-rpc headers when used with g++. Moved BEGIN_C_DECLS
  inside ifdef (reported by Scott Zhang).

* [fix] Added regtest (test-01-e1) to check vortex_listener_unlock
  before vortex_listener_wait support..

* [fix] Removed ## declaration in front of __VA_ARGS__ inside
  vortex_connection.h headers.

* [fix] Added a new function to create default connection options
  object. Fixed CONN_OPTS macro to use this new function (fixed using
  __VA_ARGS__ which is not supported in visual studio). Reported by
  Ralf Konusch.

* [fix] Making vortex reader loop to also check for automatic thread
  pool resize to avoid having all threads in the pool blocking due to
  long running tasks, causing the thread pool to be not resized.

* [fix] Fixed several compilation errors inside vortex core and
  PyVortex when debug log is not enabled. Reported by Ralf Konusch.

* [fix] Reorganized automatic thread pool resizing code to be checked
  from inside vortex reader to ensure we can resize even in those
  cases where all the pool is busy for a long time. Added regression
  test to reproduce the bug and check fix introduced

* [fix] Adding show connection errors to regression tests..

* [fix] Making vortex_channel_reply_ref to return axl_bool signaling
  if the ref process was ok. Used this to fix close in transit bug
  found on systems heavy loaded with low memory.

* [fix] Updated regression tests that creates local listeners to use
  "0" to allocate a random port to avoid problem with port reuse in
  low memory or slow systems running the reg test.

* [fix] Fixed problem with g++ compilers when used code generated by
  xml-rpc-gen (strings marshalled for xml-rpc c stub). Reported and
  fixed by Scott Zhang.

* [fix] Making VortexChannel to acquire its own reference to VortexCtx
  instead of relying on VortexConnection's reference (which can be
  nullified on connection close, but channel reference may remain
  because the user acquired additional references). Checked reg
  tests. All fine.

* [fix] Importing latest checked lua-vortex
  implementation. Reorganized compilation infrastructure to fit into
  current libvortex-1.1 building system. Everything keeps
  working. Nice!

* [fix] Adding missing files to build documentation..

* [fix] Improved configure.ac process to check if indeed there is a
  python and a lua suitable installation to create py-vortex and
  lua-vortex bindings (even in the case the user requests it).  Added
  some fixings to lua-vortex testing to not break when sasl or tls
  modules aren't enabled.

* [fix] Making installation to detect if lua install dir announced by
  pkg-config really exists to create it if is not the case.

* [fix] Updated Vortex pull API to include a new event to notify when
  a connection is ready to use or its setup is ready (like listeners
  connection). Event added:


  Updated pull API to include a function to easily print event type
  names. API added:

   - vortex_event_get_type

  Updated regression tests to check this new event to ensure everything
  is working. 

* [fix] (minor change) Changed debug message from thread pool to
