Please amend the title as M26 and M28 have been launched on Dec 26.
Launch time should be approx. 00:58 UTC.

The past were M25/M26, the exact launch time can be calculate after detail NOTAMs.

The December launch was M26/M28 according to https://www.csno-tarc.cn/en/system/constellation .
As of time, we'll see in two weeks.

JSR lists the 26 December 2023 satellites as Beidou DW 57 (Beidou-3 M25?) and Beidou DW 58 (Beidou-3 M26?). The Chinese "Test and Assessment Research Center of China Satellite Navigation Office" web site looks pretty official, so I think M26 and M28 are correct for the last launch. This launch might be M25 and M27.

I've corrected GCAT to show M26 and M28 for the last launch.

Launch success has been officially confirmed, with CAS Shanghai confirmed as the manufacturer for these 2 satellites. Some official reports also indicate them to be the final satellites of the 3rd generation Beidou satellites.

Alter Sachse, what's the link for your screenshot? Your image is showing that the satellites are M27 and M28.
