@@ -47,6 +47,7 @@ Highlights:
 * I'm still working on "compatibility hints".  Unfortunately, documentation is still missing.  The gist of it:
   * Use `features: posteo` instead of `url: https://posteo.de:8443/` in the connection configuration.
   * Use `features: nextcloud` and `url: my.nextcloud.provider.eu` instead of `url: https://my.nextcloud.provider.eu/remote.php/dav`
+  * Or even easier, use `features: nextcloud` and `username: tobixen@example.com`
 * **Major refactoring!**  Some of the logic has been pushed out of the CalDAV package and into a new package, icalendar-searcher.  New logic for doing client-side filtering of search results have also been added to that package.  This refactoring enables possibilities for more advanced search queries as well as client-side filtering.
   * For advanced search queries, it's needed to create a `caldav.CalDAVSearcher` object, add filters and do a `searcher.search(cal)` instead of doing `cal.search(...)`.
 * **Server compatibility improvements**: Significant work-arounds added for inconsistent CalDAV server behavior, aiming for consistent search results regardless of the server in use. Many of these work-arounds require proper server compatibility configuration via the `features` / `compatibility_hints` system. This may be a **breaking change** for some use cases, as backward-bug-compatibility is not preserved - searches may return different results if the previous behavior was relying on server quirks.
