AJAX Page and File Tree
The page- and filetree in the TYPO3 Backend are now rendered faster through extensive use of CSS and AJAX. With that it is quicker to collapse or expand branches of the folder list or the page tree because the whole tree does not have to be reloaded every time. Also, the initial loading time and the HTML size have been decreased immensely.
Clean-up functions (command line scripts)
TYPO3 4.1 features a command line interface through the system extension with the extension key "lowlevel" for checking database integrity and cleaning up such as lost files and references, flushing deleted records and published versions and much more. There is a howto-textfile inside the lowlevel extension that describes in detail how the process should be run.
Improved Extension Manager
The Extension Manager requires less memory when executed. It now stores the list of extensions from TER in the local database.
UTF-8 for filenames
On the road to a fully UTF-8 enabled Core, it is now possible to have filenames in (nearly) all UTF-8 characters.
To enable the feature, just enter the install tool in the Backend and set the option "forceCharset" to "utf-8" and enable the "UTF8filesystem" checkbox.
