The release cycle for WordPress 3.6 isn’t going to start until January, but we can of course start to drop in some early things before then. (This worked out nicely before the start of 3.5.)

With that in mind, I have added jQuery 1.9 BetaBeta A pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. 1 to trunktrunk A directory in Subversion containing the latest development code in preparation for the next major release cycle. If you are running "trunk", then you are on the latest revision.. It comes with a migrationMigration Moving the code, database and media files for a website site from one server to another.

These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party for deprecated/removed features, and this migration plugin issues warnings in the console so we may fix them. Yes, we are likely to ship the migration plugin in 3.6 final; that’s why it exists.

A side note: If you are using the WordPress Beta Tester plugin and wish to go back to the 3.5 branchbranch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch"., you can do so by changing the update stream setting from “Bleeding edgebleeding edge The latest revision of the software, generally in development and often unstable.

Minor Releases often make improvements to existing features and functionality. nightlies” (which is currently 3.5.1-alpha) and then downgrade. Of course, we’re happy to have you testing the 3.6 branch, which will be kept fairly stable throughout its development.
