The latest release contains several critical bug fixes in the garbage collection algorithm. Currently GC for single thread application looks pretty stable. GC for multi-threading applications is still not 100% operational. It works quite ok for anagram sample (probably the most memory consuming STA program up to date). But chatserver (multi-threading program) crashes. GC is the prime suspect. Lock implementation was fixed as well.
Several critical bug fixes were done for structure fields (#216) and open arguments(#211).
Several samples were ported to Linux platform. It is still behind Windows one. When Linux debugger will be finished, probably the work will be accelerated.
A lot of small enhancements were done for LIB30. There are 100 Rosetta code task implemented for ELENA now. As a result new functionality was introduced in system'routines, extensions packages.
