James or someone,

Which internal version are we talking for this change? Is it with the version 1.24wmf7 that went out yesterday? Next week's version? Been there for weeks ...?

If we are going to alert our communities to be aware, knowing the internal version is quite helpful.

Regards, Billinghurst

After a long time, we are finally upgrading the jQuery package that

ships

with MediaWiki, and so is used by many extensions, gadgets and site and user scripts. This upgrade fixes a lot of bugs, but also cleans up a lot of deprecated and dubious functionality from early versions of jQuery.

Code which uses the removed functionality is currently working due to a short- term hack, jQuery Migrate, that provides the removed functionality and outputs a warning to the console log whenever it is activated.

The jQuery Migrate hack will be removed in the (Northern Hemisphere's) Autumn of 2014. This means all extensions, gadgets, and user & site scripts on

your

wikis that still make use of jQuery legacy APIs will need to be upgraded

before

then or they will break.

== What can I do? ==

If you are a developer, please follow the instructions in the posts to wikitech-l about how to check and upgrade your wiki's gadgets, site and user

scripts

[0] [1]. If your wiki uses copies of other wikis' gadgets, please make sure that your wiki is using the latest version. There is also a tracking bug for all the extensions deployed on Wikimedia wikis which use the old code, which will be fixed before the support hack is switched off. [2]

If you are not a developer, you can check your browser's console log to

see

if there are any warnings tagged "JQMIGRATE". If you find any, please raise them in your community so you can work together to make sure they are addressed

in

time.

If you are a wikiambassador, please make sure your community is aware of this change and that any developers, gadget authors or script experts who

write

code for your wiki know that this is coming and are working to fix any

issues.

If your community is unable to fix any issues you have, please ask for help on

this

list so that we can assist you.
