+1 Thanks for taking care of the release Christian! [1] Christian's recent Jekyll experiment on the `asf-staging` branch of `logging-site` repository confused the INFRA and it is acting strangely. This will *NOT* be an issue when we push the website changes to production, i.e., `asf-site` branch. Though we will try fixing `asf-staging` anyway in the meantime. This release incorporates a humongous amount of infrastructural changes to the project that Piotr and I have been working on for months. My personal favorites: 1. Support for parallel Maven builds! First run is always a bumpy one due to the mysterious ways plugins operate. Though so far I have been enjoying `./mvnw -T2C install -DskipTests` or `./mvnw verify -T2C -pl \!:log4j-mongodb3,\!:log4j-mongodb4` a lot! See the `-T2C` there? Yup! (Embedded MongoDb server library's initial setup functionally doesn't support concurrent runs.) 2. Stellar CI support! We migrated all Maven-based projects (`logging-parent`, `-log4j2`, `-log4j-tools`, `-log4j-scala`, `-log4j-kotlin`, `-log4j-transform`, `-log4j-jmx-gui`) to a unified CI infrastructure where they all share the same automated release process and `dependabot` auto-merge voodoo! Christian single-handedly cutting this release himself is a solid proof of this convenience. 3. Major-version-specific URL convenience: https://logging.apache.org/log4j/kotlin/latest (redirected to `1.x`) https://logging.apache.org/log4j/kotlin/1.x Notice the `latest` and `1.x`? We *will* apply the same practice to Log4j too. You will eventually be seeing: https://logging.apache.org/log4j/latest (redirected to `2.x`) https://logging.apache.org/log4j/1.x https://logging.apache.org/log4j/2.x https://logging.apache.org/log4j/3.x 4. Every dependency that is upgradable is upgraded.
