You probably won't have noticed (unless you scrutinise the format of Recent Changes like I do...), but we've just (i.e, within the last few days) had an upgrade on the MediaWiki software to its latest release version - 1.14.
Amongst the minor cosmetic changes, there are two upgrades of great importance, particularly to admins, since they are they only ones (as yet) who have access to these.
- It is now possible to change the length of a block on an IP address or username without having to unblock and then reblock.
- It is now possible to move images! This is something we've been after for some time now, as we've increasingly had images uploaded under bad or nondescriptive file names - until now, to rename an image, you had to delete the image and re-upload it at the new name. This resulted in the image upload history being lost. No more.
