This is a bugfix release, fixing many issues present in GHC 8.10.5, including:

- A fix for segmentation faults in GHCi on `aarch64-darwin` due to
   an incorrect foreign import in `haskeline`. See [this blog
   post](https://www.haskell.org/ghc/blog/20210709-capi-usage.html) by Ben Gamari
   for more details on how your library could be affected.

- A fix for a critical bug affecting Haskell Language Server (HLS) among other
   applications caused by missing RTS symbols required for statically linked
   builds of the GHC library (#19763).

- No longer emitting spurious warnings for LLVM versions (LLVM 9-12) that were
   actually supported (#19973, #19829, #19959).

- Numerous bug fixes for the new LLVM based `aarch64-darwin` backend (#20132).

- Fixes and stability improvements for the non-moving GC (#19715).

- Many other bug fixes for the RTS (#18033, #20132, #20093, #19421).

- Many packaging related fixes, including versioned `ghc-pkg` executables
   (#20087), and actually distributing GHC versions linked against the
   `integer-simple` big integer backend (#18967, #19953) on both Windows and Alpine
   Linux. Previous releases were still linked against the `GMP` library due to a
   misconfiguration of the builders.

- A significant refactoring of `process` fixing numerous bugs mostly on
   Apple platforms (#19994, [process refactoring](https://github.com/haskell/process/pull/208)).

- A FreeBSD release after fixing issues that caused GHC 8.10.5 to be unable to build
   (#19958, #19948).

- Bug fixes for the linker on Darwin platforms (#20004, #19968, #19950).

A complete list of bug fixes and improvements can be found in the [release
