@bmansurov - did we identify any next steps on this?

@ovasileva could you clarify what you mean? I think this task is self-containing.

Change 333805 had a related patch set uploaded (by Jdlrobson):

I've +2'ed the above patch. Any plans to update the README file as well, @Jdlrobson?

It seemed an inline comment was most appropriate here.

We should document the config variables in a readme and how they behave but I don't see how this would help protect us against license issues like that in the incident since there is no config switch that impacts it.

This task is about documenting caching implications gotchas around the licensing-related config variables and not necessarily licensing issues themselves. A note in the README seems appropriate.

There are no licensing related config; that's my point. The inline comment is most appropriate in my opinion then a out of context note in a read me... Which is done.

Mibad. I'd assumed that the free-by-default behaviour was flagged…

^ Thinking about my assumptions: am I correct in assuming that we announced the new default on a mailing list?

I couldn't find an announcement, though this is likely not finding the right Google incantation. The most recent changes have been discussed a number of times on reading-wmf and well documented on mediawiki.org.

I think this task can be considered done since the new behaviour is the default and it's not flagged.

I suggest we discuss the new default as part of sign off for T152216.
