T35235 <https://phabricator.wikimedia.org/T35235> has been around since
2011, and it's now fixed with the merge of Gerrit change 183315
<https://gerrit.wikimedia.org/r/#/c/183315/>. For the effects this will
have for bots and other API clients, see the announcement on
mediawiki-api-announce
<https://lists.wikimedia.org/pipermail/mediawiki-api-announce/2015-April/000079.html>
.
For developers, this means that it's much easier to provide formatting for
your log entry parameters: it's now *possible* for extensions, and no
longer hard-coded in ApiQueryLogEvents for core.
If anyone is looking at updating existing log entries or creating new ones
for improved parameter formatting, you should be able to get the general
idea from the core formatters I did in that Gerrit change. But don't
hesitate to ask me for help if necessary, and please do add me as a
reviewer on relevant changesets.
Thanks!
