Here's the changes that were announced after a 4 hour meeting between Merkel and the VDA (German car industry organization):
No length limit additions were announced. Note that since this is an
extension of the existing incentives program, I believe any new restrictions would have been announced. (But this is not certain.)
So in principle it's possible that they have agreed on other changes as well, I believe it's very probable that they'd have announced any such changes.
The main anti Tesla move here is the €40,000 limit of the €6,000 incentives: just below the €44,000 of the base SR+.
Other than that all of these changes are positives, in particular the new €65,000 upper limit should now include a fully maxed out Model 3 Performance as well, which costs €64,720 currently. Most Model Y trims should be covered as well.
According to press reports the new incentives package will be finalized and announced in November, I.e. within the next few weeks.
