How to release a new version?

1. Every change on the main development branch is released as -SNAPSHOT version to Sonatype snapshot repo at https://oss.sonatype.org/content/repositories/snapshots/io/github/nettyplus/netty-leak-detector-junit-extension/
2. In order to release a non-snapshot version to Maven Central push an annotated tag, for example:

git tag -a -m "Release 0.x.y" v0.x.y
git push origin v0.x.y

3. At the moment, you may not create releases from GitHub Web UI. Doing so will make the CI build fail because the CI creates the changelog and posts to GitHub releases. We'll support this in the future.
