The GHC developers are very pleased to announce the availability of the release candidate for GHC 9.10.2. Binary distributions, source distributions, and documentation are available at [downloads.haskell.org][] and via [GHCup](https://www.haskell.org/ghcup/).GHC 9.10.2 is a bug-fix release fixing over 50 issues of a variety of
severities and scopes, including:* Significantly improved performance when dynamically loading Haskell symbols (#23415).
* Fixing a bug where the simplifier sometimes destroyed join points during float out, which could impact performance (#24768). * Reduced memory fragmentation in the non-moving GC's segment allocator, improving resident set size by up to 26% for some applications (#24150). * Added new flags to control speculative evaluation (-fspec-eval and -fspec-eval-dictfun) to work around performance regressions (#25606). * Fixed several platform-specific issues, including segfaults with FFI on PowerPC (#23034) and improved code generation for AArch64 with multiway branches now using jump tables (#19912) * And many more!A full accounting of these fixes can be found in the [release notes][]. As
always, GHC's release status, including planned future releases, can be found on the GHC Wiki [status][].We would like to thank Well-Typed, Tweag I/O, Juspay, QBayLogic, Channable,
Serokell, SimSpace, the Haskell Foundation, and other anonymous contributors whose on-going financial and in-kind support has facilitated GHC maintenance and release management over the years. Finally, this release would not have been possible without the hundreds of open-source contributors whose work comprise this release.As always, do give this release a try and open a [ticket][] if you see
anything amiss.Cheers,
