ANN: HBase 0.90.5 available for download

[Stack <st...@duboce.net>]

HBase 0.90.5 is available from your Apache mirror of choice:

 http://www.apache.org/dyn/closer.cgi/hbase/

HBase 0.90.5 is a maintenance release that fixes ~80 issues over
version 0.90.4 while retaining API and data compatibility. The release
notes may be found on Apache JIRA [1].  We recommend that all
upgrade to 0.90.5.

Users upgrading from previous versions of 0.90 may upgrade clients and servers
separately, though it is recommended that both be upgraded. If upgrading
from a version of HBase prior to 0.90.0, please read the notes accompanying
that release [2].

Thanks to those who contributed!

When integrating HBASE-5102 I found the following issue which would leave
stale connection hanging around if you use HBaseAdmin.
This only happens when "hbase.connection.per.config" carries value of
false. In 0.90.5, its default value is true.

We're discussing releasing 0.90.6 in January.

Stay tuned.
