[leerho <le...@gmail.com>]

### HLL Merge Speed Improvements + Bub Fix! ###

Hello All,

1. The Apache DataSketches Java 1.2.0-incubating has been released!

    NOTE 1: This is the core Java component of the DataSketches library
that includes all the sketch algorithms in production-ready packages. These
sketches can be called directly from this component or used in conjunction
with the adaptor components such as Hadoop Pig, Hadoop Hive, or the
aggregator adaptors built into Apache Druid.

    NOTE 2: This release contains some signifiant merge speed performance
improvements and a fix for a recently discovered bug identified by Issue
#292. It was fixed with PR #293, which contained other documentation and
code cleanup unrelated to the bug.  The specific files changed relating to
the bug:

    - [main/.../datasketches/tuple/Union.java](

=====
*Disclaimer*

Apache DataSketches (incubating) is an effort undergoing incubation at
The Apache Software Foundation (ASF), sponsored by the Apache Incubator
PMC. Incubation is required of all newly accepted projects until a
further review indicates that the infrastructure, communications, and
decision making process have stabilized in a manner consistent with
other successful ASF projects. While incubation status is not
necessarily a reflection of the completeness or stability of the code,
it does indicate that the project has yet to be fully endorsed by the
ASF.
