A new version of SetEXIFData , my GUI for exiftool by Phil Harvey , is now available:

v8.2
(15 May 2020)

Fix:

Keyword-entry is now handled correctly, when entering each keyword on a new line and/or separated by commas and/or (semi)colons.

Keywords are also added again to the 'subject' attribute, which is used by Preview and other Mac apps.

Keywords are now sorted and de-duplicated automatically.

These changes were necessary, since I found out that a lot has changed since 2008/2011, in the programming language and the Mac apps.

New:

I dropped 32-bit support. Only the 64-bit application will be maintained.
