Maintaining a changelog for each new version or release of Podman helps
users to quickly skim for new changes. Add a `make changelog` target to
facilitate creating a new log.
There are two env variables to control the base and target commit for
the new log. The output gets prepended to the changelog.txt file, which
is a textfile in following format:
- Changelog for $(CHANGELOG_TARGET) (ISO-8601 DATE):
* Commit subject
* Commit subject...
Notice that the list of commit subjects excludes merge commits, and can
be manually modified after generation if needed.
`CHANGELOG_BASE=v0.3.2 CHANGELOG_TARGET=v0.3.3 make changelog` would
generate the following shortened output to the changelog.txt file:
Changelog for v0.3.3 (2018-03-17):
* Bump to v0.3.3
* Fix build after c/image changes
* Update containers/image
* Fix E2E tests
* Address review comments
* Fix E2E tests
* Add restart to main podman manpage
* Add podman restart to podman bash completions and commands
