Plasma 5.11 is announced but the link is incorrect at: https://www.kde.org/announcements/plasma-5.11.0.php If you scroll down, you can see a link towards: https://www.kde.org/info/plasma-5.10.95.php This is incorrect; it should point towards https://www.kde.org/info/plasma-5.11.0.php instead. Not sure if this is appropriate to file here - there are so many entries, it's hard to know where to file what.
Is this still an issue? I don't see any 5.10.95 link in the source code of the first link.
This was fixed not long after that it was reported: https://websvn.kde.org/?view=revision&revision=1499781
