The PTF restricts the use of the ADDPFTRG command - this is a breaking change documented in the Memo to Users.

Just two days left until the first hearing in Newag's lawsuit against us (Dragon Sector members) and SPS. It will take place on 28.08.2024 at 10:00.

Pretty sure I'm still going to be having these discussions at the 10 year anniversary.
