Micronaut Framework 5.1.5 Released!

The Micronaut Foundation is excited to announce the release of Micronaut Framework 5.1.5!

It includes Micronaut Core 5.1.15, which updates managed Netty to 4.2.18.Final.

We strongly recommend that users update to Micronaut Framework 5.1.5, as Netty 4.2.18.Final is a security release containing several security fixes.

If you are using Micronaut Framework 4, update to Micronaut Platform 4.10.18. It includes Micronaut Core 4.10.28, which also updates managed Netty to 4.2.18.Final.

If you are using Micronaut Framework 3, update to Micronaut Core 3.10.12, which updates managed Netty to 4.1.138.Final. Netty 4.1 will reach end of life on July 1, 2027. Thus, this is a good time to update to Micronaut Framework 5.
