+Changes are normally committed to the main branch first, then, if they're backward-compatible, cherry-picked to a branch.
 
 When you commit a change, resolve the issue in Jira. When resolving, always set the fix version and assign the issue. Set the fix version to either to the next minor release if the change is compatible and will be merged to that branch, or to the next major release if the change is incompatible and will only be committed to trunk. Assign the issue to the primary author of the patch. If the author is not in the list of project contributors, edit their Jira roles and make them an Avro contributor.
