==== TODO ==== * Tests would be nice. * Possibly add more keywords to allow control over additional edge cases. * Add shortcut format option for the release/issue URI settings - GitHub users can just give their GitHub acct/repo and we will fill in the rest. * Maybe say pre-1.0 releases consider all bugs 'major' (so one can e.g. put out an 0.4.0 which is all bugfixes). Iffy because what if you *wanted* regular feature-vs-bugfix releases pre-1.0? (which is common.) * Make sure regular ``:issue:`` is documented.
