High level summary​

The Developer Experience team has been dealing with day-to-day troubleshooting and support of various elements including build failures, compiler upgrades, CI migration from Cicero to Hydra, and Buildkite to GitHub Actions. iohk-nix, haskell.nix, and devx have seen improvements.

Lower level summary​

build support & maintainance​

The DevX team has helped troubleshoot a few CI issues, and focused on helping to migrate from Cicero to Hydra, as well as from Buildkite to GitHub Actions.

compiler upgrades​

Compatibility with 9.6 has been continued and most of our libraries are not 9.6 compatible. Only a few are not, we hope to have this done by the end of the month. We've also started preliminarily adding GHC 9.8 to our infrastructure for early compiler regression tests.

Hydra Tools​

Our repository, input-output-hk/actions, has seen quite some improvements to facility the hydra <-> github integration.

haskell.nix​

Haskell.nix has been maintained and updated with the addition of preliminary GHC 9.8 support.

devx​

The devx repository has seen significant improvements, including the addition of GitHub Codespaces, and DevContainers. Integrated with our actions/devx GitHub Actions, we have a consistent set of tooling for

  • nix develop shells
  • GitHub CodeSpaces integration
  • VSCode DevContainer support
  • GitHub Actions integration

upstream tooling​

Our team remains committed to enhancing upstream tooling, with ongoing contributions to GHC, Cabal, and Nix.
