This is a dot, dot version quickly following the recent release of Lr Classic 7.3 which produced unusual crash reports for some users on Mac OS and a backup issue affecting Windows users. A list of the bugs fixed in v7.3.1 is given below:
-fixed the issue of backup catalog getting corrupted on Windows.
-after launching 7.3.1 all the lua based Presets (lrtemplate files) will be re-converted to XMP and lrtemplate files names will be prefixed with a double tilde icon e.g. ~~PresetName.lrtemplate).
-fixed the issue of Presets not getting converted completely.
-fixed the issue of incorrect Sort Order for Presets.
-fixed the crash occurring on Mac while performing CMD+Z after applying profiles.
-fixed the crash occurring on Mac after applying some Profiles.
In addition to the above fixes, Adobe has released a config file which customers can install if they prefer to disable live previews for Profiles while hovering in Loupe view. This is hopefully a temporary work around and I would like to see it replaced in future versions with a simple preference setting that customers can switch on/off.
