Geotagging was broken in v9.3 an now works again. The newer version of Xojo I used, needed another plugin to get the geodata.
Subseconds/sequence number when used with an interval and initially left zero, the Subseconds/sequence number of the first image would not be set to zero.
Added a '%.d', '%.s' and '%.t' as placeholders when renaming files. The '.' indicates that dates and times will be formatted with a dot: YYYY.MM.DD and/or HH.MM[.SS].
Added the possibility to add additional and preferred EXIF / IPTC / XMP tags. Add preferred tags inside the preferences window, these always will be listed first in the main window under 'Add other tags', where you can also add other tags for one-time useage. Writeable tags unknown to exiftool will be marked by prepending them with a '?'.
Added tags that have no value or begin with a '?' are not processed. Valid tags with values are processed before everything else, to prevent overruling of other settings in SetEXIFData.
