The Play Team is happy to announce the release of Play 2.9.8! 🥳

📗 About this Release

This release fixes several bugs and a CVE, improves Scala 3 support, and - as always - updates dependencies. We strongly recommend upgrading at your earliest convenience.

If you're considering upgrading to Play 2.9, please check the Play 2.9 release announcement for highlights and further details on how to migrate. Many projects have already smoothly upgraded to Play 2.9.

sbt 1.9.0 or newer is now required

Because of recent changes in how artifacts are published to Maven Central, older sbt versions can no longer retrieve Play's sbt plugins published starting July 1, 2025. If you're still using an older sbt release, you'll need to upgrade to sbt 1.9.0 or newer to continue fetching Play artifacts from Maven Central. Play 2.9.8 and newer will not work with earlier sbt versions. To be fair, when releasing Play 2.9, we already announced 1.9.0 as the minimum required sbt version, even though older versions may still have worked until now.

Scala 3 improvements

  • Twirl now supports using in it's templates, so you can define template parameters like:

    @(x: Int)(using y: Int)

    Thanks to @ajafri2001 for implementing this improvement 🙌:
    playframework/twirl#933 Prepend "using" at the callsite when definition site has implicit parameter

  • When using Play JSON, the JSON field ordering is now correctly preserved when compiling with Scala 3 - implemented by @xuwei-k:
    playframework/play-json#1177 fix field ordering Scala 3 writes macro
