Accelerator 2.5.0 has been released
and is now the recommended version, it adds additional data for crashes caused by C++ exceptions and SourceMod plugins, and the installed SourceMod version is now displayed as part of the crash metadata. As part of this work, support for SourceMod 1.7 or older has been dropped.
Upgrading to SourceMod 1.10 build 6431 or later is highly recommended, as it contains changes to optimise SourcePawn native calling and significantly improves stack traces from crashes that happen during calls to SourcePawn.
It still needs integrating into the standard processing pipeline to be displayed everywhere, but for now the new SourcePawn stack information can be found on the "View Raw" page on crash reports from fully updated servers.
Also, fixed quite a while ago but not noted here, new Accelerator builds will work on SRCDS versions that use old libstdc++ versions again, so you've got no excuse not to update!
EDIT: There was an issue with early Windows builds not including the SourceMod version, that is now fixed.
