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.
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
usingin it's templates, so you can define template parameters like:Thanks to @ajafri2001 for implementing this improvement 🙌:
Prepend "using" at the callsite when definition site has implicit parameter 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:
