Short description of error
When you go on website https://wiki.blender.org/wiki/Reference/Release_Notes/, it says
Expression error: Unexpected < operator.
However URL https://wiki.blender.org/wiki/Reference/Release_Notes does work (without the last slash)
It should point show "Page Not Found!" as on the other pages.
Also, it would be great if all of those pages with missing or additional slashes pointed to the same page, like on Blender Download page
