Noteworthy Pull Requests

• With this release, we are disabling HTTP pipelining in the Play Pekko HTTP backend. HTTP pipelining has not been thoroughly tested within Pekko HTTP and was already disabled in Pekko HTTP itself some time ago. Beyond benchmarking purposes, it is not recommended for practical use, and there is minimal actual usage from common client libraries in their default settings (web browsers do not support it anymore). Furthermore, having HTTP pipelining enabled could lead to Play unexpectedly canceling POST requests with large bodies.

• Netty native transports under Linux (enabled with play.server.netty.transport = "native") now support AArch64 and RISC-V out of the box in Play:
  • Make Netty native transport work on Linux AArch64 and RISC-V (besides x86-64) #12405 Make Netty native transport work on Linux AArch64 and RISC-V (besides x86-64) by @mkurz
• Play and Twirl are now compatible with Scala 3.4.0. However, it's important to note that Scala 3.4.0 is not a Long-Term Support (LTS) release, and Play officially supports only Scala LTS versions (currently Scala 3.3). This compatibility is provided as a best effort. Consequently, if you choose to upgrade beyond Scala 3.3, you do so at your own risk, and you should not expect support for issues that may arise.

• You now have the option to disable the generation of JavaScript (reverse) routers if you do not utilize them, potentially enhancing the performance of your build:

• This release includes numerous dependency upgrades, notably:
  • netty-transport-native-epoll 4.1.107.Final (was 4.1.104.Final) #12367 netty 4.1.107.Final (was 4.1.104.Final) by @scala-steward
  • pekko-http 1.0.1 #12358 pekko-http 1.0.1 by @pjfanning
• Last but not least, over the past weeks (indeed, months), efforts have been made to transition Play and all its dependencies away from the deprecated (and read-only) repo.typesafe.com and repo.scala-sbt.org repositories. As a result, with this release, all dependencies (including those for testing) are now hosted exclusively on Maven Central. This change ensures that even if one of the deprecated repositories were to become unavailable (as has happened in the past), your projects would not be affected. Moreover, this move allows for the possibility that, 15 years from now, you could still download the Play 3.0.2+ source code and, with just Java and sbt installed, rebuild Play from the sources (assuming Maven Central is still operational, which is more likely). While this may seem a bit far-fetched, we occasionally receive reports from users attempting to rebuild an ancient Play release but are unable to do so because they cannot retrieve all the necessary dependencies.
