rc/v2.15.6.1

v2.15.6.1 (release candidate)

Release notes:

• This release fixes potential bugs.

Changes since v2.15.5:

Major changes:

• Stack 2.15.5 and earlier cannot build with Cabal (the library) version 3.12.0.0. Stack can now build with that Cabal version.

Behaviour changes:

• Stack's StackSetupShim executable, when called with repl and stack-initial-build-steps, no longer uses Cabal's replHook to apply initialBuildSteps but takes a more direct approach.

Bug fixes:

• Fix a regression introduced in Stack 2.15.1 that caused a 'no operation' stack build to be slower than previously.
