I imagine Google modified the sitemaps-related search developer documentation final week. I’m not certain if any of the content material particularly modified, however Google did rename among the pages and create new pages, possibly to consolidate the content material and make it simpler to know and entry.
Google additionally added a brand new part named combining sitemap sections. Google additionally changed the “cut up up your giant sitemaps” with “handle sitemaps with sitemap index file.” I didn’t dig by every file to see precisely what modified however you could wish to.
Here’s a side-by-side of the outdated construction versus the brand new construction, with the added “combining sitemap sections” within the sidebar:

Discussion board dialogue at Twitter.
Replace: Google informed us “primarily based on person suggestions, we revamped our documentation about sitemaps. Notably, we diminished duplication between the sitemaps protocol and our documentation, added extra examples to our documentation about sitemap extensions, and added a brand new doc about how one can mix sitemap extensions.”
