I have updated webtrees.net/download to show a link to 2.0.15
(I forgot to update this after the release).
> and webtrees‑2.1.0.zip which is a bit confusing.
I found a problem with 2.1.0 just before I released it.
I expected the fix to come really quickly (it is in somebody else's library), and it was
easier to let the website be out-of-date for a day or two than to undo all the updates.
But I'm still waiting for another library to publish a fix. Any day now....
