[Haskell-cafe] ANN: stack-2.3.0.1 release candidate

[Emanuel Borsboom]

### First release candidate for v2.3

**Changes since v2.1.3**

Release notes:

Major changes:
* `setup-info-locations` yaml configuration now allows overwriting the
default locations of `stack-setup-2.yaml`.
  [#5031](https://github.com/commercialhaskell/stack/pull/5031)
  [#2983](https://github.com/commercialhaskell/stack/issues/2983)
  [#2913](https://github.com/commercialhaskell/stack/issues/2913)

* The `setup-info` configuration key now allows overwriting parts of
the default `setup-info`

* The `--setup-info-yaml` command line flag now may be used in all
stack commands such as `stack build`, and not only in `stack setup`

* The `--setup-info-yaml` may specify multiple locations for
`stack-setup.yaml` files.

* The `stack upload` can read first reads environment Variable
`$HACKAGE_USERNAME` and `$HACKAGE_PASSWORD` if they are missing only
then asks for `username` or `password`

* Fully remove GHCJS support.

* Remove the `freeze` command. It has been replaced by lock files.

Behavior changes:
* Remove the deprecated `--stack-setup-yaml` command line argument in
favor of `--setup-info-yaml`
  [#2647](https://github.com/commercialhaskell/stack/issues/2647)

* We now recommend checking in generated cabal files for repos. When
generating lock files for
  extra-deps that only include `package.yaml` files, a deprecation
warning will be generated.
  Also, those packages will no longer be included in the generated lock files.
  See [#5210](https://github.com/commercialhaskell/stack/issues/5210).

Other enhancements:
* Add `build-output-timestamps` flag in yaml. Setting it to true
  prefixes each build log output line with a timestamp.

* Show warning about `local-programs-path` with spaces on windows
  when running scripts. See
  [#5013](https://github.com/commercialhaskell/stack/pull/5013)

* Add `ls dependencies json` which will print dependencies as JSON.
  `ls dependencies --tree`  is now `ls dependencies tree`. See
  [#4424](https://github.com/commercialhaskell/stack/pull/4424)

* Remove warning for using Stack with GHC 8.8 and Cabal 3.0.

* Allow relative paths in `--setup-info-yaml` and tool paths
  [#3394](https://github.com/commercialhaskell/stack/issues/3394)

Bug fixes:

* Upgrade `pantry`: module mapping insertions into the database are now atomic.
  Previously, if you SIGTERMed at the wrong time while running a script, you
  could end up with an inconsistent database state.

* `--resolver global` doesn't retrieve snapshots list from the internet
   beause doesn't need it. See
[#5103](https://github.com/commercialhaskell/stack/issues/5103)

* Fix using relative links in haddocks output.  See
  [#4971](https://github.com/commercialhaskell/stack/issues/4971).
* Do not include generated cabal file information in lock files. See
  [#5045](https://github.com/commercialhaskell/stack/issues/5045).

* Use proper Hoogle executable path when installed automatically. See
  [#4905](https://github.com/commercialhaskell/stack/issues/4905)

* Fix GHC version for batched package unregistration. See
  [#4951](https://github.com/commercialhaskell/stack/issues/4951)

* Use Hoogle from the snapshot used and not the latest version. See
  [#4905](https://github.com/commercialhaskell/stack/issues/4905)

* Resolve "'stty' is not recognized". See
  [#4901](https://github.com/commercialhaskell/stack/issues/4901)

* Fix missing reconfigure check causing errors when a package gets
  used in multiple projects. See
  [#5147](https://github.com/commercialhaskell/stack/issues/5147)
