Google has also updated the crawl stats report help documentation last week. Google made a lot of support documentation changes in the past week including product rich results, Googlebot doc, job posting help doc, moving the HTTP status codes doc and also this crawl stats report help document.

- Using a 12hr – 30 day timeframe for fetching
- Details about homepage usage
He posted the document before and after changes as well:
