See [https://haskellstack.org/](https://haskellstack.org/) for installation and upgrade instructions.

Release notes:

- This release fixes potential bugs. Given the change in the default value of the `urls` key, Stack users are recommended to update to this version to avoid having to configure that key in YAML configuration files.

**Changes since v2.15.3:**

Behaviour changes:

- Following the handover of the Stackage project to the Haskell Foundation, the default value of the `urls` key is `latest-snapshot: https://stackage-haddock.haskell.org/snapshots.json`.
- Stack no longer includes the snapshot package database when compiling the setup executable for a package with `build-type: Configure`.

**Thanks to all our contributors for this release:**

- Mike Pilgrem
