Hey,
Starting with version 1.24wmf21 (which will be deployed to production wikis starting 11 September), MediaWiki will no longer execute JavaScript code on Microsoft Internet Explorer 7 (previously the cutoff was MSIE6, as of last month).
This is for the same reasons that we stopped JavaScript on MSIE6 [*] – the browser is not actively supported by its manufacturer, and this prevents users with this browser from experiencing a number of bugs.
As with last week, this change will be communicated through tech news as well, but please help carry this message into your communities as appropriate.
Yours,
