Hi Kai-Uwe,
These are errors fixed in 1.13, though. See for example ReadICCAscii,
which no longer exists in latest sources. There are, however, other
small bugs that I've fixed in my development sources. Perhaps it would
be a good idea to do the release of 1.14 as a maintenance one. I tend
to do releases each 5-6 months to minimize noise, and was planning
some new features for 1.14, but those can wait as well...
Opinions?
Regards,
Marti.
