We are pleased to announce the release of version 5.0 of the [PL/Haskell extension](https://github.com/ed-o-saurus/PLHaskell/releases/5.0). This extension allows users to write PostgreSQL functions in the Haskell functional programming language. Instructions can be found [here](https://github.com/ed-o-saurus/PLHaskell/blob/main/README.md).
Version 5.0 adds the ability to work with date/time types and advisory locking. Users of Ubuntu and Fedora can install the extension directly from the rpm and apt [repositories](https://github.com/ed-o-saurus/PLHaskell/blob/main/docs/Package_Repositories.md). If you have problems with the extension or a feature request, please submit a Github issue.
