Embarcadero used a slighly different solution. Instead of adding the FNotifier field, they replaced the FRegex field with FNotifier. The code then uses the FRegex reference held by FNotifier to access the relevant TPerlRegEx instance. This bug has been fixed in Delphi XE2. Embarcadero used a slighly different solution.

An "interface change" is a change made to the interface section of a unit. An interface change requires all units that use the changed unit to be recompiled. Embarcadero doesn't make interface changes in updates because it would break compatibility with all 3rd party components for which you don't have source code that use the changed unit.

doesn’t work if you have an empty comma, for example

ID,NAME

will only return “TEST”
