 NetBSD Storage Roadmap
 ======================

 Note however that implementing ext3 has already defeated several
 people; this is a harder project than it looks.
 
- - As of May 2016 there is a GSoC project to implement read-only ext4
-   support, but (it not being summer yet) no particular progress.
+ - GSoc 2016 brought support for extents, and also ro support for dir
+   hashes; jdolecek also implemented several frequently used ext4 features
+   so most contemporary ext filesystems should be possible to mount
+   read-write
+ - still need rw dir_nhash and xattr (semi-easy), and eventually journalling
+   (hard)
  - There is no clear timeframe or release target.
- - Contact ?? for further information.
+ - jdolecek is working on improving ext3/ext4 support (particularily
+   journalling)
