The Lufthansa group have a few capacity increases this winter ex-MAN.
As well as the known daily Austrian Airlines route to Vienna, loaded into the schedules are the following.
Munich
Nightstopper upgrades from scheduled A320 to A321. Other 2 flights upgrade from scheduled A319 to A320.
Frankfurt
All 4 flights now scheduled to be A321, instead of A320/A321 mix.
Swiss
Back to using A320's Mon-Thu and Sun. Fridays sees Helvetic E190 on both flights, Sat sees Swiss A320 and Helvetic E190
Hamburg, Dusseldorf and Cologne remain unchanged at present.
I appriciate LH often throw whatever on the MAN routes, but, the upgrades are based on what was scheduled to operate the flights
