* Adopt keep a changelog
Ref: https://keepachangelog.com/en/1.0.0/
* Add changelog to release and contributing docs
* Use H2 for automatically added Download section
The individual changelog subsections use H3 and the changelog section
uses H2, so the Download section should use the same heading
* Add already present changes to changelog
* Mention changelog issue references in CONTRIBUTING.md
Whenever a release is published, this action will create a release
archive and update the release body with a download section.
This also integrates the suggestions from #2276Resolves#2276
We no longer allow people to create issues from a blank template.
The templates for bug reports and build issues are also much more
explicit in what they want from the user.
The issue tracker should be for bugs only. Right now actual bugs can
easily fall through the cracks because we get stuck answering questions
and basically providing tech support.
This move is also intended to have more traffic to our subreddit and IRC
channel with the hope that the community can also help itself out.
