People keep talking about it...
I've been using the presto plugin for yum for a while now (a year? can't remember) but only now it is being pushed as a "cool new feature". Did I miss something here?
Presto allows you to download only the deltas of updated RPM packages, which makes the updates' size decrease a lot and, by consequence, speeds up the updating process. I guess it reached stable status recently and I wasn't paying close attention
UPDATE: So the changes are not actually on how the plugin works, but actually on how it accomplishes its tasks. Now this is new

It's now integrated into the Fedora build infrastructure. That's new-ness of it.
The underlying technology has been working for a while..but the deltarpm payloads have been produced as a community effort and hosted externally up till now. And required some manual configuration by users to setup.
And that's not meant to belittle that community effort. Its because of that sustained community effort that made it important that presto be integrated into the common infrastructure. it just took time to do it.
Fedora is now in a position to produce these deltas as part of the standard package update process and hand appropriate deltarpm mirror information to clients via MirrorManager.

Before Fedora 11, you had to add manually an external repository with presto metadata and deltaRPMs, as those were not included in the official repositories.
For Fedora 11, work has been done on the build and updates systems. So now, when you build a new version of a package and request it to be pushed to the repositories, all the magic is done so that the user can use presto when updating :)
That's why it's a Fedora 11 feature, even if it's been available for a long time now.
