Yes and no!Do you mean they activating compability mode without the knoweledge of the users?
They logically disactivated (did the necessary changes in the ( C )API, and gave to know to the user by friendly comments in the ( C )API), but they never gave knowledge to the user by a clearly understandable post in the forum. This modification was only one of the daily(?) quiet changes of the ( C )API.
@Pedro: I never have had the opinion about you and your API, that you change your mind from day to day and publish a new version of your excellent product.
You usually took many Latin days of test, before publishing a new version.
