LUFS Meter 1.4.2
2016 04 11
Changed the installers on OS X and Windows such
that the previous plugin files get deleted before
they get replaced. Otherwise it happened on OS X as
well as on Windows that even though the files got
replaced, they kept the creation and modification

Pro Tools) do use the creation date flag to
determine if they need to rescan a plugin.

connected to the Internet, you can unlock the
Discounted or the full LUFS Meter from within the
The token generator needed to be changed. Before it
could happen that the 32 bit and the 64 bit
versions on Windows showed different tokens. A
similar discrepance occurred on OS X with Garage
Band and everything else. -> Unfortunately, you
need to activate your LUFS Meter again. If you are

pop up and guide you through the process.
