Plone.releaser

------------------

New features:

- Changed new headings to 'Breaking changes', 'New features', 'Bug
fixes'. Old headers are still accepted, but in the postrelease we
generate the new ones. In the unified changelog, we combine the old
and new names.

Bug fixes:

- When compiling changelog, treat Incompatibilities header as special
too. [maurits]

------------------

New:

- Added prerelease hooks to cleanup empty headers. [maurits]

- Add header 'Incompatibilities:' in postrelease. In prerelease check
if at least one of New, Fixes, Incompatibilities is there.
See https://github.com/plone/Products.CMFPlone/issues/1323 [maurits]

----------------

New:

- Removed our 'show changelog' entry point. Required zest.releaser
6.6.0 that has this itself. [maurits]

- Show ``New:`` and ``Fixes:`` in unified changelog. [maurits]

- Require ``New:`` or ``Fixes:`` to be present in the changelog during
prerelease.
[maurits]

- Simplified showing last changelog entries. Requires zest.releaser
6.0 or higher.
[maurits]

- Set new changelog format during postrelease. Adapt check in
prerelease that warns when the original changelog text has not been
changed since the previous release.

Fixes:

- Temporarily require simplejson. This is needed because launchpadlib
requires lazr.restfulclient which needs a new release. See
https://bugs.launchpad.net/lazr.restfulclient/+bug/1500460 [maurits]

----------------

- Fail nicely if a Plone versions.cfg can't be located
[esteele]

- When showing the changelog, accept 1.7.2.1 as version. So loose
version numbers instead of strict version numbers with only one or
two dots.
[maurits]

- Run git pull on buildout.coredev to make sure it is up-to-date.
[timo]

- Refactor checkPackageForUpdates to be more flexible. Made it a class
on its own module.
[gforcada]

- Create a jenkins report based on checkPackageForUpdates.
[gforcada]

----------------

- Rename esteele.manager to plone.releaser.
[timo]

----------------

- add feature: add the package to the version file if it doesn't exists
[jfroche]

- add command to set the package version in a versions config file
[jfroche]

- return the new version number when appending jenkins build number to the versions of a package
