Hi folks! The Apache HBase 2.3 release line reached the end of maintenance in October 2021. Our apologies for the late notification.
The final release was 2.3.7 and is available from archive.apache.org. No further releases from branch-2.3 are planned. Users of HBase 2.3.z should upgrade to the current stable release (currently 2.4.10) as quickly as possible. Thanks to all the contributors who helped make HBase 2.3 possible over its lifespan.
