Try to provide simple examples demonstrating the issue at hand; describe what happened as well as what you would have expected to happen instead.

Reproduction-instructions shall be expressed in terms of Haskell.org's standard tooling (i.e. cabal).

Be aware this is a F/OSS project; the software is provided "as is" for no charge and you're entitled in terms of support to what you payed for.

Development & support is done primarily using Haskell.org's standard tooling, i.e. cabal; we don't have time & energy to support everyone's favourite third-party tooling.

Haskell packages are subject to the Haskell Package Versioning Policy which governs both the API versioning as well as the specification of dependency versions.

Generally, only properly released major versions of tools and libraries are actively supported in Hackage releases; this is reflected in the dependency version constraints (see also previous item).

When relaxing upper bounds for dependencies in order to declare compatibility with new major versions, it's not sufficient to merely rely on CI; make sure to review the API changes prompting the major version increment to ensure that the version relaxation is indeed safe/sound.
