As previously promised, an upgrade release of Semplice Version 2 has now been made available. It fixes the issue whereby several distros now appear to be shipping Version 7 of ImageMagick (the image manipulation program) rather than the Version 6 that was being shipped on all distros when Semplice Version 2 first shipped. If you try issuing Version 6 commands when you have Version 7 of ImageMagick installed, you get ugly warnings about 'convert is deprecated in IM7'.
Since it's not entirely clear to me which distros have decided to run with ImageMagick 7 and which have chosen to stick with ImageMagick 6, I've had to add code to Semplice which works out what version is installed and then use the appropriate image editing commands accordingly.
This is a minor update, therefore, in the grand scheme of things: there's no fundamental change in the way Semplice works, nor in the way it does what it does. Nevertheless, if you are trying to run Semplice on a distro that uses ImageMagick version 7, this is a very important patch release! It's just slightly annoying that the need for it has arisen just a fortnight after the program's initial release!
A tiny bug-fix of no consequence is also introduced: if you were to do Semplice's volume boosting, and your recording literally had an existing peak volume of 0dB (i.e., it was already at the loudest it could be without introducing clipping or distortion), the original code would have turned that into a null value which would then have triggered a visual error message: ugly but ignorable. The bug-fix takes care of that situation in a non-visually intrusive manner!
Anyway: upgrading Semplice is a matter of taking the Miscellaneous menu, Option 3 and then following the prompts. Once the upgrade has been downloaded and installed, quit Semplice completely and then re-launch it to have the changes properly picked up and applied. You may see error messages as you perform that initial program quit, but these can be ignored. If Semplice re-launches itself in working order, all is fine.
