v0.20 - Probably Australian

Features

The big focus for this release is pagination support. This lets the caller
control how much data to retrieve for GetAll* endpoints throughout Octokit.
This was a team effort to apply this across the entire codebase, with
contributions from @dampir, @devkhan, @prayankmathur, @samthedev and @shiftkey.

For more information about how to use pagination in your projects refer to the
documentation: http://octokitnet.readthedocs.io/en/latest/extensibility/#pagination

Breaking Changes

• IUserKeysClient.GetAll() was named incorrectly when it was originally implemented
  and only works for the current user's keys. Update all usages to GetAllForCurrent().
• CompareResult.MergedBaseCommit was never deserialized correctly, and has
  been marked as obsolete. You should use CompareResult.MergeBaseCommit
  instead (note the lack of a d).
• IEventsClient.GetAllForRepository was incorrectly retrieving issue
  events before this release. Use the new IEventsClient.GetAllIssuesForRepository
  method if you still require issues, or continue to use IEventsClient.GetAllForRepository
  if you require all repository events.
• IUsersClient has a property named Keys which has been renamed in the
  GitHub API documentation - Octokit has added the name GitSshKey to
  reflect this change, and Keys will be removed in a later release.
• ItemStateFilter has been introduced to separate it from the search APIs, which still use ItemState. This affects IssueRequest.State, PullRequestRequest.State and MilestoneRequest.State. You'll need to rename any enum usages from ItemState to ItemStateFilter.
