Apache Hive 0.8.0

Apache Hive 0.8.0 came out on Dec.19th. The list of new features, improvements, and bug fixes is extremely long.

Just as a side note, who came out with the idea of having a Hive fans’ page on Facebook?

Redis 2.4.5

Redis 2.4.5 was released on Dec.23rd and provides 4 bug fixes:

Last but definitely one of the most important announcements that came in December:
