Generate changelog in changelog/@unreleased

What do the change types mean?
  • feature: A new feature of the service.
  • improvement: An incremental improvement in the functionality or operation of the service.
  • fix: Remedies the incorrect behaviour of a component of the service in a backwards-compatible way.
  • break: Has the potential to break consumers of this service's API, inclusive of both Palantir services
    and external consumers of the service's API (e.g. customer-written software or integrations).
  • deprecation: Advertises the intention to remove service functionality without any change to the
    operation of the service itself.
  • manualTask: Requires the possibility of manual intervention (running a script, eyeballing configuration,
    performing database surgery, ...) at the time of upgrade for it to succeed.
  • migration: A fully automatic upgrade migration task with no engineer input required.

Note: only one type should be chosen.

How are new versions calculated?
  • ❗The break and manual task changelog types will result in a major release!
  • 🐛 The fix changelog type will result in a minor release in most cases, and a patch release version for patch branches. This behaviour is configurable in autorelease.
  • ✨ All others will result in a minor version release.

I believe the problem is that https://github.com/square/javapoet/blob/b314337267eb36462c3bf67a87494e614c9c8b40/src/main/java/com/squareup/javapoet/Util.java#L101 isn't expansive enough in what requires the \u0000 style escaping.
