Here is the most recent update per the Discord earlier today.
"Personally, I have been bogged down by the vehicle customization update for far too long due to it's size and complexity. The longer it took, the more demotivating it had become for both me and Paulius. It has been exhausting mentally as I could have released a dozen smaller and much more impactful updates in the same amount of time. For example, the arraignment form was a good addition, for me it was a needed distraction, didn't take much time to do, and it currently benefits at least 3 groups of players (criminals, PD/SD, JB). I still plan to release the vehicle customization update eventually, I may manage to do it by the end of this month, but I don't want to promise that because it is difficult to estimate exactly and may eventually lead to disappointment. If it is not done by November, then the roadmap takes top priority in order to fulfill the deadlines and only the remainder of spare time will be dedicated to completing the customization update."
