 # Revision history for ghcup

+## 0.1.22.0 -- ????-??-??
+
+### New features
+
+* Beef up `--overwrite-version`, fixes [#998](https://github.com/haskell/ghcup-hs/issues/998)
+  * e.g. `ghcup compile hls -g master --overwrite-version='%v-%h' --ghc 9.4.8` will produce a binary called `haskell-language-server-wrapper-<version-from-cabal-file>-<short-git-commit-hash>`... refer to `ghcup compile hls --help` for more information
+* Allow to set ghcup msys2 environment wrt [#982](https://github.com/haskell/ghcup-hs/issues/982)
+* Add mechanism to warn on new metadata versions, fixes [#860](https://github.com/haskell/ghcup-hs/issues/860)
+
+### Improvements and bug fixes
+
+* Clean up on git clone errors, fixes [#1004](https://github.com/haskell/ghcup-hs/issues/1004)
+* Error out on empty UserSettings wrt [#922](https://github.com/haskell/ghcup-hs/issues/922)
+* Fix failure mode when metadata is garbage, fixes [#921](https://github.com/haskell/ghcup-hs/issues/921)
+* Be less confusing when user tries to 'set' ghcup in TUI, fixes [#923](https://github.com/haskell/ghcup-hs/issues/923)
+* Fix prefetch for cross bindists
+* Fix misinterpretation of '+' in URI paths, fixes [#408](https://github.com/haskell/ghcup-hs/issues/408)
+* Stricter (and better) file uri handling
+* Set LD=ld.bfd on Alpine linux during bindist configure
+* Add rocky/void detection
+* Logging improvements
+* Remove the "show all tool" config in the TUI
+* Fix opening changelog on windows
+* Don't remove share dir link prematurely
+* Require user to explicitly choose subcommand for 'ghcup config'
+* Don't download twice when trying stack decoding
+
+### Refactoring and maintenance
+
+* Large TUI code cleanup by @lsmor (Luis Morillo)... more coming up soon
+* Allow building with `tar` instead of `libarchive` (mainly to make contributions easier)
+

 * `GHCUP_MSYS2`: Has to point to the root of an existing MSYS2 installation (when installed by GHCup, that's e.g. `C:\ghcup\msys64`). GHCup bootstrap takes care of this usually.
+* `GHCUP_MSYS2_ENV`: The [MSYS2 environment](https://www.msys2.org/docs/environments/) to use when executing e.g. `ghcup run --mingw-path`. Possible values are `MSYS`, `UCRT64`, `CLANG64`, `CLANGARM64`, `CLANG32`, `MINGW64`, `MINGW32`. Defaults to `MINGW64`, `MINGW32` or `CLANGARM64`, depending on the architecture. `MSYS` is always added as the last component. If you change this value after running the bootstrap script, you may need to make sure that the cabal config reflects this change, more specifically `extra-prog-path`, `extra-include-dirs` and `extra-lib-dirs`. (**NOTE: specifying anything other than the default is considered experimental**)
