Yep, seems we forgot to reflect #286 there.

[marcandre]

Right. I'll add the entry

[Earlopain]

Sorry about that. If I'd knew this would have been released immediately I'd have added this myself. That change didn't seem worth documenting on its own.

[marcandre]

No biggie. It's true it didn't necessarily need a log entry, but it looked a bit strange without any detail.
Since this gem is very stable, there's no point in waiting for more changes, we release as soon as changes are made.
