+- Debconf: separate groups by first slash in name
-	- v1/v2/v3 support
+- SQLite: drop table doesn't autorefresh nav since callback is late
-	- option to use namespace separators for virtual buckets
+- Build
-- SQLite:
+	- Build own liblcl binaries in docker
-	- drop table doesn't autorefresh nav since callback is late
+	- Win32 icon resource
-	- more accurate type handling
