Hello all,

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

## Changelog for `Cabal-`

This release of `Cabal` is a point release that allowed us to get some important features out into the ecosystem that just couldn't wait:

- Include cmm-sources when linking shared objects

- Prefer canonicalized path when guessing tools from GHC path

- Fix `cabal test --enable-library-coverage` for modules in the `other-modules` field

- set the PATH_SEPARATOR value to `;` when calling `./configure` on Windows (this is necessary for autoconf >=2.7)

- Significant speedups to the solver

## Changelog for `cabal-install-`

This is the fourth release of the 3.0 release series for `cabal-install`, introducing features and quality of life improvements including:

- Better support for `hsc2hs`, allowing users to pass additional options

- Added an `--only-download` flag

- extra-packages now works properly

- `cabal init` UX improvements

- GHC 9.2 support

- Fixes to the backpack UX

- Removing the spurious warnings for extraneous versions on internal packages

- Alerts and spelling suggestions for mispelled comands

- Massive improvements to code organization and repository health

## Plans for 3.8

The 3.6 release marks the first in a series where we work to modernize the Cabal project by means of doing away with the idiosyncratic and historical cruft built up, improving the contribution experience.

Over the next 6 months, we'll be working hard to improve the state of the repository, including onboarding more maintainers and welcoming new contributors with clearer contribution requirements. To start, we've identified issues and new features that we aim to tackle for the 3.8 release spanning the following:

- Better build info for tool creators

- Support for stable package sets like LTS

- Dropping build/test support for GHCs outside of the 5 year window

- Finishing the multilib work

- a byte-for-byte bidirectional parser

- etc.

You can find the full list of 3.8 project issues here: https://github.com/haskell/cabal/issues?q=is%3Aopen+is%3Aissue+project%3Ahaskell%2Fcabal%2F14.

I'd also 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! And a special thank you to the Haskell Language Server team for working with us and the Haskell Foundation to help fund work needed to improve the IDE.

Happy hacking!
