Point release for preliminary ghc-9.14 support

[erikd]

I am using the first alpha release, ghc-9.14.0.20250819, and one of our packages depends on algebraic-graphs and the current version on Hackage does not compile with this compiler. However, the one here on Github compiles quite happily and the tests pass if I add a cabal.project file containing:

packages:
  ./

tests: True
test-show-details: direct

if impl (ghc >= 9.14)
  allow-newer:
    , inspection-testing:base
    , inspection-testing:ghc
    , splitmix:base

Hi there! I'm not familiar with cabal.project files. Do you know if we can fix the build simply by bumping some bounds in the .cabal file?

[erikd]

There is not really much to know about the cabal.project file. All you need to know is that the cabal.project never gets uploaded to Hackage and only affects local development.

This issue that is solved by:

if impl (ghc >= 9.14)
  allow-newer:
    , inspection-testing:base
    , inspection-testing:ghc
    , splitmix:base

cannot to my knowledge be solved any other way. Those libraries have not yet had their base upper bounds fixes on Hackage and this is the only way I know to tell cabal to ignore these particular upper bounds (and then only for matching compiler versions).

So, if you uploaded a new version of alga based on my PR and someone wanted to use it with ghc-9.14 they would need to have a cabal.project file containing (at least) the same allow-newer stanzas.

BTW, I am now using the ghc-9.14.1 release version.
