There have been a lot of features added since the 4.36.9.139 version of the firmware.
I have tested and used every iteration of the new firmware since it was updated to 4.36.10.xxxx and have experienced minimal issues, most of which have been fixed.
Right now, if you use Alexa devices to stream your cams, you might want to hold off as there seems to be an issue they are working on with Alexa.
Some of the new features the new FW version will add: Support for full recording capacity past 90GB on 256GB SD Cards, ability to only record AI events to the cloud rather than all motion events, ability to selectively toggle notifications for specific AI Events that have been uploaded rather than all of them.

The Release Notes & Firmware page on the Wyze Knowledge Articles Help Site will also give you an indication of the features that have been added. Since you are on 4.36.9.139, all features added after that version will apply to your update. There have been four 4.36.10.xxxx versions released.
