Something new could be in more 1 hour ? I know no new build. Maybe new colored icons for non-insiders ?
Technically, it's still not in RTM / GA phase yet. For production machines, it's prudent to wait a few days.
You know what I mean. Just to clarify, at least for others not so much aware of various sub-versions and "releases", as sometimes posts don't get through with their true meaning. Because we compare with 1909 - 18363.xxx. 18363.356 was pre-release, but those starting 1909 with this version, were treated by Microsoft like being on true release, with like-normal updates. 18363.387 was another intermediate version of 1909, next significant in line and with the same updating treatment from Microsoft. 18363.418 was the first release ISO and as such what most people would call "RTM" although this is terminology officially deprecated, still having a useful meaning. The meaning of "RTM" would be that this is the first safer version of the series, fully supported, but not the safest, as this would be the version released to businesses, about 3 months later. In the same way, except for totally unexpected circumstances, many (myself included) believe that 19041.1 is good enough to upgrade and 19041.84 - current is as good as 18363.356 or 18363.387 were at their time, but still not RTM. Anything in the middle like 19041.21 has a higher degree of risk and is not recommended. In WSUS 19041.84 is labelled as "Windows Insider Pre-release Feature update to Windows 10 (<edition, i.e. consumer or business>) version 2004.
