Possibly not clear from the title: 2.4.0 final was just released. All the new users are strongly encouraged to use this instead of 2.2.x.

Existing users should plan an upgrade to 2.4 if possible in order to take advantage of the new features.

A list of improvements is available here: http://antirez.com/post/everything-about-redis-24.html

Also possibly not clear from the title: that it's about redis. I was a bit confused (though it worked as click-bait)

Great news. The 2.4 rc11 release has been stable in my experience, I'm looking forward to the update. Thank you for all your work on redis.

Thanks, it is quite a lot of time we don't have a bug report for 2.4 that is severe or not in common with the 2.2 code base, so we decided to release it as stable. We also have big users already using 2.4. However now that it is the default download I expect 2.4 to be more stressed :)

when do we get support for lua/scripting in redis?

Either 2.6 that is the current unstable -cluster +scripting, or possibly 3.0 will ship directly with both cluster and scripting.

Please don't wait for 3.0 for scripting, using it in unstable has been very effective for me.

Ok, I'll try to push forward the plan for 2.6 as hard as I can. I'm sure shipping 2.6 and 3.0 is a bit more time consuming than shipping everything into 3.0, but actually it can be worth it. Thanks for your feedback :)

will the scripting work in clustering mode the same way it would work with a single redis instance?

Definitely not clear from the title: This is Redis 2.4.0.

Redis is one of the most stable components of our architecture -- thanks for the great work.

We're probably going to run it as a slave for awhile w/ a 2.2 master -- will be interesting to see how much memory we save, especially with copy-on-write improvements.

We have been running redis in production for months now and have never ever had a SINGLE problem with it. This, all while doing 17,000+ commands per second!

Just as a word of warning, Redis 2.2 cannot read rdb or aof files created by 2.4 (meaning I'm pretty sure 2.2 can't be a slave of 2.4. So, if you have a fail over scenario, you might be forced to upgrade your master to 2.4.

Good point. Hopefully karma will shine upon us :)

Is there an official Ubuntu PPA repo, that serves the latest redis version.

I did find some here, but they look older?: https://launchpad.net/ubuntu/+ppas?name_filter=redis

The repos update too slowly for them to be up to date on Redis, at least at the current pace Redis is moving at. You can find the latest build here: http://redis.io/download

it's pretty simple to build and install. Setting up a production environment takes a few more steps. Here are a couple of posts that will get you there: http://www.denofubiquity.com/nosql/412/ http://jramirez.tumblr.com/post/2589232577/prime-time-redis-...

Those are both written for 2.2, but my config still works fine with 2.4 using settings derived from those posts.
