changed the LDPC-Staircase codec license for CECILL (i.e. the content of the src/lib_stable/ldpc-staircase/ directory only). There is no change for the rest of the library that remains under a CECILL-C license.
solved a bug in the LDPC-Staircase matrix creation algorithm when N1 is even. This bug makes the codec non RFC5170 compliant (!). However there was no impact with odd N1 values. This means that with an even N1, an application using version >= 1.3 will not interoperate with an application using version <= 1.2.
with LDPC-Staircase, when N1 is even, the latest repair symbol is often NULL. This property is now exploited at the decoder to generate it automatically and pass it to the decoder. When this property applies, there is no need to send this repair symbol. A new OF_CTRL_LDPC_STAIRCASE_IS_LAST_SYMBOL_NULL is added to check this property within an application, if desired (e.g. this optimization is added to eperftool).
Solved a bug in the generate_curves.pl script when using prepared SQL statements. Thanks to the forum's users :-)

The OpenFEC library contains several components:

Stable codecs	This library gathers several stable, well evaluated, and sometimes standardized, AL-FEC codecs. This is the priviledged library for those who want to want to use these AL-FEC codes in operational environments.
Advanced codecs	This library gathers several codecs that are less stable by nature, e.g. because they are used to evaluate new codes or decoding techniques. This is the priviledged library for those who want to evaluate their own proposals using the facilities provided by OpenFEC.org.
Performance evaluation tools	These tools are meant to evaluate the performance of the various codes/codecs under several circunstances, for several metrics, in an automatic way. This is the priviledged set of tools for those who want to evaluate their own proposals. They can also be used with external codecs after minimal modifications.
Code generation tools	These tools are meant to ease the creation of new codes. Associated to the performance evaluation tools, they are a powerful way for testing new ideas.
Demonstration applications	These applications provide examples of how to use the library and its codecs.
Documents	The library includes both man pages that describe the various API for the users, and doxygen documentation for those who want to better understand its inner structure.

Additional information, not included in the distribution, is available in the OpenFEC.org web site.
