New WearoOS4 beta for GW4/5 and (not that reliable) release date schedule

• First, new wear os 4 beta is rolling out (nothing fancy in term of change log)
• according to site samlover (which was pretty low quality, not so original content so far, but still :) ) one can expect WearOS 4 for GW4/5 release on week 35 - the last week of August.

for me personally, week 35 would be great timing.
