      Release Notes: This version adds a new improved decoding algorithm, in which memory requirements have been reduced by an order of magnitude. It also features a small bugfix for an issue where at session initialization a variable was not correctly reset, which could lead to problems if using and reinitializing an FEC session several times.

        Release Notes: This release added a new Triangle codec for improved decoding with small FEC expansion ratios. Intel IA-64 Itanium architectures are now supported on Linux. By default, the "Optimized memory consumption of matrices" feature was invalidated as it impacted on LDGM-Triangle performances. If you only need LDGM-Staircase, you should re-activate it.
