With the release of Pynagram 1.0, Pynagram is now mature and I do not intend to make any more feature releases, unless I find a good reason to do so.
I will try to fix any new bugs that are reported and I expect they'll be some as Pynagram will be entering stable versions of Debian and Ubuntu later this year.
Till then, if you have any suggestions for a new feature, file a bug! Tell me why you think that feature is nice, and I'll consider it.
