Hello Haskell,

The Cabal team is excited to announce the release of `Cabal-`, and `cabal-install-`.

## Changelog for `Cabal-` and `cabal-install-`

This is the fifth release of the 3.0 release series for both packages. This minor version release introduces a set of fixes for some regressions seen when the tool interacts with `autoconf`, as well as some fixes for regressions to the way Paths_ modules interact with non-standard preludes:

- Making Paths_ modules work with non-standard preludes again [#5962]( https://github.com/haskell/cabal/issues/5962 )

- Generate Paths_ module with qualified Data.List.last import so that compatibility with non-standard preludes is not regressed compared to cabal 3.4.

- Windows: redo the fix to breakage caused by new autoconf; the wrong fix made cabal sometimes fail with old autoconf [#7494]( https://github.com/haskell/cabal/issues/7494 ) [#7649]( https://github.com/haskell/cabal/issues/7649 )

- Reverts #7510 that failed on Windows when used with pre-generated scripts included in packages such as network, time, process.

- Adds a subtler fix/workaround for the deficiencies of new autoconf versions on Windows.

**IMPORTANT NOTE**: The last bug affects configuration files generated with `autoconf-2.70` or later. They will not work with `cabal-`. Please either upgrade to `` or the new `` releases.

I'd like to thank the many contributors who offered patches, tickets, and other help in the preparation of this release. We appreciate all of your help!

Happy hacking!
