This is a small patch that fixes an authenticated denial-of-service attack when uploading a malicious SVG. I'd advise patching now - simply obtain a new copy of index.php via any of the usual methods described in the main README.
It also brings a teensy new feature to file preview pages, and finally fixes a nasty bug whereby strange things would happen if you tried to save an edit to a page with an ampersand in its name.
Added
- Added an input box with auto-generated short markdown embed code with copy button to file pages
Changed
- Added 1920 as a preset image size on file pages
