Outdoor camera FW updates

I noticed last week that the outdoor camera FW update post went away???
about 1+ weeks ago one of my two cameras reverted back to v1.18.23 from the v1.20.xxx
Today I noticed that camera updated FW to v1.20.37.8185

My other outdoor camera still has not updated.

Any update on what's going on? Is this a new v1.20.xxx?
