Will the territory controlled by Ukraine/Russia change significantly at any time before January 1, 2024? This would include major territorial gains or capture of important cities/objects.

Possible examples: Russian capture of Zaporizhzhia/Kherson, Ukrainian Capture of Melitopol. Not sufficient: capture of cities like Bakhmut (little strategic importance or territorial gains).

The resolution will be subjective to a degree, feel free to ask about any particular cases.

UPD: Changed closing date to Jan 2, 2024, in order to have a bit time for reports to surface. Since the question is about significant change, this should be enough. The resolution cirteria is still about front line change in 2023.
