In order +to minimise out-of-date breakage and allow maintainers to have a solid chance +of getting their packages into the newest LTS, we try to do the following: + +Make an early announcement (in the form of a blog post, typically) of the new +GHC release on the nightly build and the planned deadline for the new LTS release. +Make it clear, that in the time coming up to this, we hope package maintainers +will upgrade their packages to allow for the new GHC release. + +We prefer to prune packages causing upper bounds constraints **after** the LTS +release to allow the maximum amount of packages to get into the newest LTS. + +After the first LTS release, the package pruning process may begin in order to +move forward with getting the latest versions of packages compatible with the +new GHC release. + +[GHC upgrade note]: https://github.com/fpco/stackage/blob/master/MAINTAINERS.md#upgrading-to-a-new-ghc-version
