Today, Microsoft has announced the release of the update officially to Insiders, though there was no mention of rings it is in.
Some users took to Twitter, confused about the update and how it differed from the one on Tuesday. Microsoft's Senior Program Manager Brandon LeBlanc replied, clearing up some of the queries:
I am told is RP and Slow rings but working to get double confirmation still on that.

The build has one minor change over Tuesday's KB3176932, as follows:
“Improved download size optimization of updates.”
Somewhat frustratingly, we still don't know what changes came in KB3176932 as a full changelog has not yet been released. All we know is that it went out to the Release Preview ring rather than Slow and Fast rings,
All we know so far is that it went out to the Release Preview ring rather than Slow and Fast rings, and that it was available for both phone and PCs.
Users who have already downloaded KB3176932 will not be offered the new KB3176934, as the changes only benefit those who have not yet installed.
LeBlanc says that a changelog is being worked on and is coming soon, so we'll keep you updated when that happens. Reportedly, some mobile users with 840×480 displays are having resolution issues on this build, so that may be worth considering before you install.
