* Update references to `master` branch to say `main`
* Update external links
* Update links in old release notes
Use tagged versions of code rather than current code
The CHANGELOG docs say that contributor names should only be included if
they are not a core committer, but historical practice has been to
always include names. Per discussion on the core team, we want to change
this guidance to explicitly recommend always including contributor
names.
This not only encourages and recognizes contributions but also helps
future contributors know who worked on different parts of the code. This
record (along with git history) provides a good reference to understand
who made certain changes or features.
This is the correct lexer for interactive console sessions, according to
<http://pygments.org/docs/lexers/>. This does require command lines to
be prefixed with `$`, otherwise they are interpreted as the output of a
command. It highlights the command nicely, including environment
variables, strings, and comments.
