This section covers notes relating to deprecated usage - i.e. usage no longer recommended. In other words, things you may be able to do successfully but actually should not. This could be for one of more of these reasons:
- The feature has been removed - no longer supported at all.
- The feature has been replaced. Legacy support may continue but should not be assumed - update to the new syntax.
- The feature does not work properly or in contexts deprecated may not give expected outcome.
Deprecated action and export codes are no longer listed, although they remain in older versions of aTbRef.
