As promised earlier, Ahven 2.3 is now released. The official release date mentioned in the package is 2013-01-24, while currently it is still 2013-01-23 in Finland, but that mostly because I managed to get everything ready a few hours earlier than I estimated. If that bothers you, ignore this message until tomorrow. ;)
Anyway, the biggest new feature is the exception backtrace reporting. It should work with all compilers, but output is different for each compiler. This is because compilers do not report backtraces in identical format. Other changes include documentation improvements and few minor bug fixes.
As usual, you can get the source code from SourceForge.
