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.

• [x] Feature

This seems like a reasonable thing to build but I don't think it should be done in this repo in particular.

[jgrazian]

@sfackler Thanks for the comment, this is fine. I was having trouble trying to figure out how these changes would play nice with the RFC-002 anyway.

Are you open to the changes exposing the conjure-codegen types and generate_files_inner so that this can be moved externally?

[sfackler]

I definitely don't want to make conjure-codegen internals public API.
