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.

Not sure what to do about the CircleCI Pipeline errors, sorry. It's my first PR in this repo.

Not sure what to do about the CircleCI Pipeline errors, sorry. It's my first PR in this repo.

I'm confused by them too actually.

Could you push another commit to see if it's still happening? The new commit can be empty:

git commit --allow-empty -m 'Empty commit to rerun CircleCI pipeline'

[gluxon]

Hm.. looks like the empty commit isn't working. Thanks for trying that though.

It looks like CircleCI uses your GitHub account, which surprises me. I would have expected it to have access to the repo directly. Sorry about that. Could you try the instructions here?

[gluxon]

Approving. Thanks for the fix @jonaswitt! I'll merge once CI passes.
