Netty 4.1.68.Final released

We are happy to announce the release of netty 4.1.68.Final. This release includes two security fixes related to compression / decompression of Bzip2 and Snappy so it is adviced to update to this version as soon as possible. Beside these security fixes this release also includes various other bugfixes. Last but not least it also adds support for Mac M1 for our native bits of netty.

The most important changes are:

  • Bzip2Decoder doesn't allow setting size restrictions for decompressed data (#CVE-2021-37136)
