## Questions this post answers

### What changed in Cabal 3.18.1.0?

Cabal 3.18.1.0 is a new release of the cabal-install tool and its related libraries, announced by the Cabal team maintainer Artem Pelenitsyn. Specific bug fixes and improvements accompany this point release, continuing the 3.18 series for Haskell's standard build tool.

_Track Cabal releases on daily.dev to stay current on your Haskell build tooling._

### Does Hasql v2 introduce breaking API changes?

No, Hasql v2 introduces no breaking changes to the API except for how the connection adapter is chosen in the connection settings. It adds a native Haskell implementation that runs without external dependencies, alongside the original libpq-based approach, letting users pick either path while keeping the same battle-tested default.

_Developers evaluating database driver upgrades can follow Hasql's evolution on daily.dev._
