Hello,
The deployment of MediaWiki 1.26wmf18 (starting on August 11) will no
longer include the legacy and deprecated sajax JavaScript library. It
has been emitting deprecation warnings since June 2013[1] (1.22).
Reedy has helpfully provided a list of affected site and user scripts on
public Wikimedia wikis on Phabricator[2]. Details on how to migrate are
provided at [3] (it should be simple to run a semi-auto find/replace bot
with a few regexes).
If you run into issues migrating or need help, feel free to ask on
wikitech-l, IRC (#wikimedia-tech) or m:Tech[4].
