Here is the changelog:
* Fixed: the detection of installed packages failed in certain cases
* Fixed: a few mistakes in the Norwegian and Russian translations
If Envy complained about the lack of some packages which it said it couldn’t install but which were already installed then this release will solve your problem.
Special thanks to cwillu, who made notice that I should have used dpkg --get-selections instead of dpkg --list. I’ll read the fine manual to the end in the future.
