I tested the file you posted. I had to massage it to remove carriage returns.

It behaves normally on 4.x:
- The target in Ekos is now the star that is being slewed to, even though the slew is still in progress. It is no longer the previous star.
- The popup notification that the mount has reached the target only happens when the slew has actually ended.
- The 'Eq. Coordinates' in INDI goes yellow when the slew is in progress, and then green when the slew ended.

So all good on my side.

We need this to go into INDI's repo quickly, because it affects lots of people, not just those who do meridian flips.

Do you want me to submit it to Jasem?
