Here is a short FAQ describing the version numbering and purpose of this series: - === Why skip from 0.20 to 0.89? === + === Why skip from 0.20 to 0.89 (0.90)? === The last few releases of HBase have been in lockstep with Hadoop releases (eg hbase 0.X.* would work with Hadoop 0.X.*). However, Hadoop's release process has slowed down, and we have the desire to release HBase on a different timeline from Hadoop, with each HBase release potentially being compatible with multiple versions of Hadoop. To signify this departure from lockstep releases, and since we intend for the next release of HBase to continue to support Hadoop 0.20, we don't want to call the next release 0.21.
