I noticed that lots of extensions were recently updated to use
mediawiki-codesniffer 0.7.1 [1].
This has some implications I think are worth being aware of:
1) Many open patches will need manual rebasing and conflict resolution.
2) Those extensions will now depend on at least PHP 5.4 due to short
array syntax [2] instead of PHP 5.3.
Both can cause inconveniences, (1) mainly for developers and (2)
mostly for users.
Some patches doing this update in a more thorough and tested way [3]
existed but were ignored. It would be nice to avoid that in the
future.
Please also watch out for code that might have got removed
unexpectedly due to a bug [4]. On quick inspection I did not see this
happening in those patches.
