From Joomla! Documentation
You have recently uploaded and for use on Security and Performance FAQs and Joomla Administrators Security Checklist. Unfortunately the very same filenames will be used in large on some 1200+ pages of the Joomla! 1.5 Framework Reference to indicate availability of a feature "since version X.Y:Z" and whether it's been "deprecated as of X.Y.Z". There'll also be File:Compat 16.png etc. as J! itself evolves and the API reference gets updated. The reference pages and images used therein are currently prepared on a test wiki.
Mind if I rename both badges to either "compat_XY_native.png" or just "native_XY.png" respectively? It'll be easier and faster to edit two pages than a thousand :-) You may also re-upload both images using a different name and update the FAQ and checklist.
While I'm here: please check your Preferences > Editing and tick Mark all edits minor by default. You mass "minor" corrections to the above pages flooded Recentchanges. "Minor Edits" can be filtered and this checkbox is also available below the edit form. The same form also features a button called "Show Preview". Please consider using this one before saving ;-)
