Changelog

See the 1.8rc2 Changelog for what’s been fixed since 1.8rc1. For a list of all issues fixed since 1.7.2, see previous 1.8 changelogs.


Upgrade Guide

A full Upgrade Guide for easing the transition between 1.7 and 1.8 is in the works. This will be ready in time for the final release. In the meantime, one of the more significant (and breaking) changes in 1.8 already documented there is a refactor of the widget factory. This means anyone that has built their own plugin that uses the widget factory will need to make a number of changes for compatibility with 1.8. For a view of these changes, see the widget factory section of the Upgrade Guide. Also, see this sample implementation of a simple widget with both the 1.7 and 1.8 widget factories, and the differences, by Scott González.


Plan for 1.8 final

We hope to release jQuery UI 1.8 final after a couple days, assuming there aren’t any blocking issues present in this release candidate.


Thanks

A big thanks to all that have worked on all the bug fixes and other improvements that have gone into this release. We’ll have a proper listing of all contributors in the final release announcement.
