You can download binaries for this pre-release from: [Release rc/v2.11.0.1 (release candidate) · commercialhaskell/stack · GitHub](https://github.com/commercialhaskell/stack/releases/tag/rc/v2.11.0.1).

Please test it and let us know at the Stack repository if you run into any trouble. If all goes well, we hope to release the final version in a couple of weeks.

**Changes since v2.9.3:**

Behavior changes:

- Drop support for `Cabal` versions before 1.22 and, consequently, GHC versions before 7.10.
- `stack ghci` and `stack repl` now take into account the values of `default-language` keys in Cabal files, like they take into account the values of `default-extensions` keys.
- Removed `--ghc-paths`, `--global-stack-root` and `--local-bin-path` flags for `stack path`, deprecated in Stack 1.1.0 in favour of `--programs`, `--stack-root` and `local-bin` respectively.
- On Windows, `stack upgrade` always renames the file of the running Stack executable (adding extension `.old`) before attempting to write to the original file name.
- On Windows, `stack upgrade` does not offer `sudo` command alternatives if attempting to write to the original file name of the running Stack exectuable results in a ‘Permission’ error.

Other enhancements:

- Add options of the form `--PROG-option=<argument>` to `stack build`, where `PROG` is a program recognised by the Cabal library and one of `alex`, `ar`, `c2hs`, `cpphs`, `gcc`, `greencard`, `happy`, `hsc2hs`, `hscolour`, `ld`, `pkg-config`, `strip` and `tar`. If Cabal uses the program during the configuration step, the argument is passed to it.
- By default all `--PROG-option` options are applied to all local packages. This behaviour can be changed with new configuration option `apply-prog-options`.
- Add flag `--[no-]use-root` to `stack script` (default disabled). Used with `--compile` or `--optimize`, when enabled all compilation outputs (including the executable) are written to a script-specific location in the `scripts` directory of the Stack root rather than the script’s directory, avoiding clutter of the latter directory.
- Better error message if the value of the `STACK_WORK` environment variable or `--work-dir` option is not a valid relative path.
- Stack will use the value of the `GH_TOKEN`, or `GITHUB_TOKEN`, environment variable as credentials to authenticate its GitHub REST API requests.
- `stack uninstall` also shows how to uninstall Stack-supplied tools.

Bug fixes:

- Fix incorrect warning if `allow-newer-deps` are specified but `allow-newer` is `false`. See [#6068](https://github.com/commercialhaskell/stack/issues/6086).
- `stack build` with `--file-watch` or `--file-watch-poll` outputs ‘pretty’ error messages, as intended. See [#5978](https://github.com/commercialhaskell/stack/issues/5978).
- `stack build` unregisters any local packages for the sub libraries of a local package that is to be unregistered. See [#6046](https://github.com/commercialhaskell/stack/issues/6046).
- The warning that sublibrary dependency is not supported is no longer triggered by internal libraries.
