Microsoft posted the changelog on its support site last night, which you can view here. It's unclear why the updates are available on the Update Catalog and not Windows Update, but it could be that the company is biding its time with a run on the Insider Release Preview ring before it gets pushed through Windows Update for everyone else, possibly on Patch Tuesday in February.
For now, you could install it manually, or just wait until Microsoft makes it available through official channels.
