This release mainly introduces nightly support. Also see: [User Guide - GHCup](https://www.haskell.org/ghcup/guide/#nightlies)

## Changelog

- Implement support for nightlies, wrt [#824](https://github.com/haskell/ghcup-hs/issues/824)
- Fix GC with XDG dirs, fixes [#810](https://github.com/haskell/ghcup-hs/issues/810)

## How to upgrade

```haskell
ghcup upgrade

```

## How to use nightlies

Nightlies are just a nother release channel. Currently, only GHC supports nightlies, which are binary releases that are built every night from `master`.

To add the nightly channel, run:

```sh
ghcup config add-release-channel https://ghc.gitlab.haskell.org/ghcup-metadata/ghcup-nightlies-0.0.7.yaml

```

To list all nightlies from 2023, run:

```sh
ghcup list --show-nightly --tool=ghc --since=2023-01-01

```

Ways to install a nightly:

```sh
# by date
ghcup install ghc 2023-06-20
# by version
ghcup install ghc 9.7.20230619
# by tag
ghcup install ghc latest-nightly

```
