As follows:

Automatic versioning of CSS and JS files in the backend. This feature 
provides automatic numbering of CSS and JS files using the files 
modified timestamp. This way the file reference will change when a CSS 
or JS files is changed, and by this the browser will re-cache the file. 
Can be configured to include the timestamp within the the filename 
(before .ext) or as a parameter to the file (default).

Could include: Developers can use this API for versioning of files in 
the own backend mods, by calling 
t3lib_div::createVersionNumberedFilename or using the core API for 
including files in the page renderer class.

Good enough? Feel free to correct / beautify / shorten / elaborate :)
