Please provide a change log
I know, I know, it's all free software and open source - you shouldn't expect anyone to do anything. However, we do want our projects to succeed and we do put them out there in hope that it will be useful to someone.
So, you can be a jerk and provide a simple .pm file, without any documentation (because "it simply works"), no toolchain configuration (you "don't need any") and no tests (hey, if it works, it works, right?).
However, CPAN ain't like that. CPAN is (mostly) well structured distributions that adhere to community standards that include: building toolchain files, metadata to help CPAN indexers and installation applications, tests, documentation (in a standard format - POD), sometimes examples folder with sample scripts using your code, perhaps a GPG signature file to have content verified and - *gasp* - a change log indicating what each version added (and perhaps when it was released too).
I'm listed to the CPAN RSS because CPAN is my language and I need to know what's up. Whenever a distribution I use has a new version out I go over the change log and see whether I need to upgrade, whether I should upgrade (for a new feature or fix) or update my code (API change?) or the likes.
However, it appears some authors - which are hell of a lot smarter than I, with much more interesting projects - do not see the point of keeping a change log. Is it a difficult task? Does it disrupt their release flow? I've prepared the last change log entry of Dancer and I can assure you that it took less than one minute. Simply "git log", checking the messages, seeing what people did since last release and deciding what is worth mentioning in the log. That's it. It's even easier if you simply add an entry after doing a change.
Currently if you don't keep a change log, I have a hard time using your project. Simply because I have no idea what's going on there unless I check the source myself. To be completely honest, I don't feel like running diff (even though there's a relatively comfortable one in CPAN) every time you make a release.
Please oh please keep a god damn change log.
