Following what the documentation specify above for the pretty permalink format (`/:categories/:year/:month/:day/:title/`), it should result for the example to `/2009/04/29/slap-chop/` and not `/2009/04/29/slap-chop/index.html`. Well, at least if I've understood correctly ;-)
This adds docs for two new permalink features coming in Jekyll 3:
- improved default permalinks for pages and collections (#3538)
- support for extensionless URLs (#3490)
