Play Framework Files

We're excited to announce the release of Play 2.9.12! 🚀

:green_book: About this Release

This release upgrades Netty to address a large number of reported security vulnerabilities (CVEs), fixes a bug in the reverse router, improves Scala 3 support in routes files 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.

Noteworthy Pull Requests

• Netty got upgraded to 4.1.138.Final, which fixes many CVEs (see the Netty security advisories): [#13953], [#13978], [#14090], [#14172], [#14250] by @scala-steward
• [#14315] [2.9.x] Fix reverse router for OptionalInt/Long/Double query params (backport [#14252]) by @arimu1 Reverse routes with java.util.OptionalInt, OptionalLong or OptionalDouble query parameters dropped the parameter name and produced invalid URLs (e.g. ?111 instead of ?key=111).
• [#13973] [2.9.x] Support Scala 3-style wildcard type arguments in routes files (backport [#13972]) by @jadenPete In addition to _, routes files now also accept Scala 3's ? syntax for wildcard type arguments.
