Due to bug 43221 and Gerrit change I1a3c7ac6, the format of the
"details" for some log events will be changing. In particular, any
event with details that were returned with a key resembling "4::foo"
will now be returned under a key of simply "foo".
This change will be deployed with 1.21wmf7, which is scheduled for
today on
mediawiki.org,
test.wikipedia.org, and wikidata; 7 January
for non-Wikipedia sites; 9 January for enwiki; and 14 January for the
other Wikipedias.
