If they would've added it in the update, it will be here in the forum posted by an Admin. If it is not here, you should wait untill either the release or more information will be shown to the Community.
While i'm still here, I have a question for the Moderation Team. A while i ago i was playing LSPDFR along with some plugins for the mod. Then a wierd thing happened, nothing said that the game or LSPDFR crashed but for some reason when i called backup all backup units were spawned, but they would stay in exact that position and do absolutely nothing. This counts for the Police peds aswell. I didn't get any "LSPDFR has crashed" message. I don't know if this bug is known and/or fixed, but i just would've like to inform the team about it.
