Tonight I’ve released SPServices 2013.01. If you are using an earlier version of SPServices, I strongly suggest that you upgrade to this version, as you will see some performance improvements and there is some nice new functionality. Thanks to everyone who downloaded the beta and provided feedback.
By far the most exciting thing in this release is jQuery promises, or deferred objects. I’ve written about this several times already here, here and here. I won’t belabor the point too much, but if you’re interested in increasing the efficiency of your code and getting ready for the way you are likely to work with the REST Web Services in SharePoint 2013, you should get familiar with using promises.
Other Release Notes
There are other goodies in this release, and you can see the full list of enhancements and improvements on the download page. Note the link to the Issue Tracker items for this release. I’ve gotten a bit lazy with the release notes, so for this release the items in the Issue Tracker contain all of the details.
