 1. All bug fixes that correct a defect that is also present in an LTS branch must be backported to that LTS branch. If a bug fix introduces a change to the API such as a new function, the fix should be reworked to avoid the API change. API changes without very strong justification are unlikely to be accepted.
 1. If a contribution is a new feature or enhancement, no backporting is required. Exceptions to this may be additional test cases or quality improvements such as changes to build or test scripts.
