This release mitigates a design flaw for TYPO3 FAL present since TYPO3 6.2 LTS: when moving a file in fileadmin, FAL reindexes it afterwards, extracts again the metadata from physical file and replaces them in database, thus effectively leading to loss of information if a user manually edited the metadata. Problem is reported but is not yet fixed and will not be fixed for TYPO3 v8 anyway (possibly with ELTS plan? Even not sure). So for v8 users and as long it is not fixed in Core, this extension will simply "refuse" to extract metadata if they are already present in file.

In addition a bug has been fixed where some PDF whose metadata where encoded as UTF-16BE in octal representation would lead to extracted title and other fields like "376377000D000o000c..." which is absolutely useless!

Finally a deprecated call was still present in TYPO3 v8 and is now migrated.
