May 6, 2012
===========
Release 0.9.0
This release adds a constructor to the C++ API, some command line options to
lcm-logger, and incorporates a number of bugfixes.
- Java
- workaround to accomodate recent changes in Automake. In particular, fixes
lcm-java for Ubuntu 12.04.
- C
- add start_timestamp option to log file provider
- fix multicast TTL issue #45
- Fixes for fragmentation of larger messages. Big messages were previously
fragmented into 1400B packets. However, since lcm_udp uses a short for
the number for fragments there can only be 64K fragments. The makes LCM
use the 1400B packet size if the message would be broken up in to less
than 64K fragments. Otherwise it increases the packet size to split the
message into 64K packets
- C++
- Add a constructor to create a C++ instance wrapping arond an existing lcm_t
C instance.

- C
- add new macros LCM_MAJOR_VERSION, LCM_MINOR_VERSION, LCM_MICRO_VERSION to
check LCM version from C/C++.
- C++
- rename LCM::fileno() to LCM::getFileno()
fileno is implemented as a macro on some platforms, and is thus
effectively a reserved keyword.
- lcm-gen
- C++ don't try to dynamically resize fixed-size arrays (re issue #42)
- Python
- bugfix in decoding multivariable arrays
- lcm-logplayer-gui
- add command line parameters to:
- start logplayer with the log paused
- filter out specific channels from being played back by default.
Oct 15, 2011
============
Release 0.7.1
This is a bugfix and maintenance release.

- fix decoding of zero-length primitive arrays (re issue #38)
- computeHash() omit parameter name if unused
- don't #include a type's own header file for recursive types
- fix memory leak in LCM::publish() (re issue #35)
- inline methods for generated code
- use static local variable for getHash() to reduce liblcm dependency of
generated C++ code
- `#include <string>` if a type has a string field
- C

- Java
- add --with-jardir=DIR option to configure script to allow configuring
lcm.jar destination directory.

API reference.

docs are still built separately.
Jun 9, 2011
===========
Release 0.6.0
This release includes a number of bugfixes and performance enhancements
- C
- Change internal buffering from a fixed size ringbuffer to
per-subscription FIFO queues. Subscriptions start with a default maximum
queue length of 30 messages, which can be adjusted using the new function
`<message_type>_subscription_set_queue_capacity()`
For example, to set the queue size to 5 for a message type example_t:
example_t_subscription_t* subs = example_t_subscribe(lcm, "EXAMPLE", message_handler);
example_t_subscription_set_queue_capacity(subs, 5);
- Explicitly disallow recursive calls to lcm_handle.
- fix synchronization issues when allocating receive resources and
conducting multicast self-test. see issue #30

- The lcm-dotnet/ directory contains a publish-subscribe library for
.NET applications.
- lcm-gen

instance = proj.msg_t()
see googlecode issue #21

bindings without a dependency on liblcm (useful if only the marshalling
aspect of LCM is desired).
- (Java) don't complain about default pkg if one is specified on cmd line.
- lcm-spy
- remember last message on each channel so that object panels open up
immediately.
- put frames in front when double clicked.
- Other
- remove manpage-specific GFDL copyright notices.
Jan 6, 2010
===========

details.
Aug 14, 2009
============
Release 0.3.1
This is a maintenance release, and incorporates a number of minor bugfixes and
enhancements.
- Java
- lcm-spy, lcm-logplayer-gui warn if gcj is detected as JRE
- minor enhancements to lcm-spy
- Python
- update comment docs
- Other
- add --lcm-url=URL cmd line option to lcm-{spy,logger,logplayer,logplayer-gui}
- updated examples
Jun 29, 2009
============
Release 0.3.0
- Java
- Faster serialization classes that provide a 4x-5x speedup. This introduces
a backwards-incompatible change to the LCM Java API. Specifically, the
`messageReceived()` method of the LCMSubscriber interface has changed from:
public void messageReceived(LCM lcm, String channel, DataInputStream ins)
to
public void messageReceived(LCM lcm, String channel, LCMDataInputStream ins)
LCMDataInputStream has an almost identical API to DataInputStream, and
migration of source code to the new API should only require changing
implementations of LCMSubscriber in the manner described above.
- C

small

Aug 29, 2008
============
Release 0.1.0
New features
- Added const declaration to .lcm specification.
- Removed transmit_only option from LCM URL. All LCM instances are now
considered transmit only until a channel subscription is made.
- Added LCM_DEFAULT_URL environment variable. If the LCM URL is not specified
during instantiation, and LCM_DEFAULT_URL is defined, then that is used as
the LCM URL initialization string.
- Added documentation for LCM type specification language.
- Added close method to Java LCM class.
Deprecations
- enum is now deprecated in the .lcm specification. Current implementations
will be left functional, but enums will no longer be documented or supported
in future releases. At some point in the distant future they may be
completely removed. Use of const instead of enums is now recommended.
Bugfixes
- Java
- fix enum types. This breaks the API for compiled Java enum types. Changed
java enum value field from private to public so that raw numerical value is
accessible.

- add mutex to allow only one thread in lcm_handle at a time.
May 5, 2008
