The Cabal developers are happy to announce the first release candidate
for cabal-install-3.4.0.0

The corresponding tag is `cabal-install-3.4-rc1`,

and there is a handful of binaries available at

    https://oleg.fi/cabal-install-3.4.0.0-rc1/

Ubuntu-16.04 bindist should work on most recent Linux distributions,

- Support for upcoming GHC-9.0
- Removal of sandboxes
- Improved public sublibrary support
- `active-repositories` configuration
- Various `cabal init` improvements
- Various `cabal sdist` improvements
