The stackage curator team has started preparations for an LTS major bump which will include ghc-8.6.2.
To give everyone some time to prepare, we are announcing the planned release date as approximately two to four weeks from the date of this post.
Getting your package into the nightly snapshot will ensure its inclusion in LTS 13 as well. To add your package, please submit a PR to commercialhaskell/stackage. To add your package to LTS 13 after it’s released, please open a new issue on commercialhaskell/lts-haskell. Please feel free to contact the stackage curators with any questions you may have via the stackage mailing list, or the stackage gitter chat.
For more insight into how stackage curators handle these sorts of things, see: the LTS major bump process.
