I have currently 3.4.22110 and F11.
Also have fmods.net like overclock, video and camera on demand installed mods.
In note says “Does JB works? YES” but, I am not sure, sorry if already asked 
If update to 3.4.23088 will it keep all my fmods installed or I should do maps update only (really do not want to install all mods from scratch again)?
