--- author: Jens Petersen title: LTS 19 release and Nightly on ghc-9.2 description: Stackage LTS 19 (ghc-9.0.2) has been released and Stackage Nightly moves to ghc-9.2.2. timestamp: 2022-03-20T05:00:00Z --- The Stackage team is very happy to announce the initial [Stackage LTS version 19](https://www.stackage.org/lts-19.0) snapshot release is now available, based on GHC version 9.0.2. This release is significant for several reasons: - not only is it the first stable LTS release based on ghc9, - it also includes many significant [upgrades](https://www.stackage.org/diff/lts-18.28/lts-19.0), including aeson-2.0 with improved security, and - it is also the largest stable LTS release we have ever done: just 1 short of 2900 packages! Of course it is still possible to get your package added to lts-19, if it builds with lts19 and you missed to get it into Nightly in time for the initial lts-19.0 build: using our straightforward process - just open a github issue in the [lts-haskell](https://github.com/commercialhaskell/lts-haskell/issues) project and following the template there. Thank you to the great Haskell community for all the many contributions you are making - do keep them coming! At the same time we are also excited to [move Nightly now to GHC 9.2.2](https://www.stackage.org/nightly-2022-03-19) - enjoy! Apparently there will be a 9.2.3 bugfix release coming, so we will update Nightly to that after it is released. Quite a number of Nightly packages had to be [disabled](https://www.stackage.org/diff/nightly-2022-03-17/nightly-2022-03-19) as part of the upgrade to 9.2. This is being tracked in : if you find your package listed there, you can help to update it to build with ghc-9.2 and Stackage Nightly, thank you! Help us make the next LTS 20 an even bigger and better release!
