This means that the Lua scripting is now available in a stable release!&lt;p&gt;Want to use Redis as a very fast bloom filter server? A couple of short Lua scripts can make it happen. Want to do some operation which would require a lot of round-trips to Redis? Turn it into a Lua script and get rid of those network round-trips. Once you get used to having this capability, it starts to feel indespensible, an essential feature that Redis would be incomplete without.&lt;p&gt;Oh, and I guess there are a bunch of other improvements in 2.6 -- reduced memory usage, more convenient command-line options for redis-server, some handy new commands, and a lot more --  but really, the Lua scripting is so good that it outshines everything else.</text></item></parent_chain></comment><story><title>Redis 2.6.0 Released</title><url>http://redis.io/download#2.6.0</url><text></text></story>
