What IS the latest version of BBS

My BBS software states “Latest version” but I see other users that have higher version… I have a P1S and my latest version as shown in BBS is V1.9.5.51, and is missing some of the features -

A1 Mini

So, how do I get this version?

BS tells me about updates when it’s started, but you can check this way also.

Clipboard01

BS update check on the Mac for those using that OS.

My apologies, I was looking at the ctrl-p page, and that lists the FIRMWARE and AMS versions, I saw that so started looking under BBS help, about BBS, missing the “Check for updates” tab, Thanks for the information!
Whenever I start BBS, I do get a popup about updates, but they always pertain to the A1 model, not P1S.
