The following is a draft announcement for the 2.1 release. I've prepared it here for a little bit of feedback, before sending it out later today.
*** The Apache Accumulo project is pleased to announce the release of Apache Accumulo 2.1.0! Apache Accumulo 2.1.0 contains numerous features and improvements, and contains over 1200 contributions from over 50 contributors. This release includes external compactions, separate scanner thread pools, separate compaction queues, per-table encryption configuration, scan servers, atomic configuration of multiple properties, more efficient use of ZooKeeper watches on configuration nodes, a convenient JShell launch script, and many, many more changes. See the release notes linked below for more details. 2.1 is an LTM (Long-Term Maintenance) release line, Users of 2.0 or 1.10 are encouraged to upgrade to this latest version. 2.0 is end-of-life immediately, and will not receive any further updates. 1.10 will reach that end-of-life in one year. Upgrades are supported directly from the latest 1.10 or 2.0.1 only, so it is recommended to upgrade to one of these first. *** Apache Accumulo® is a sorted, distributed key/value store that provides robust, scalable data storage and retrieval. With Apache Accumulo, users can store and manage large data sets across a cluster. Accumulo uses Apache Hadoop's HDFS to store its data and Apache ZooKeeper for consensus. This version is now available in Maven Central, and at: https://accumulo.apache.org/downloads/ The full release notes can be viewed at: https://accumulo.apache.org/release/accumulo-2.1.0/
