-- Many RomWBW-specific applications are locked to the ROM version

-  your disk-based RomWBW applications and OS boot files.
+- The RomWBW ROM and the RomWBW disk images are intended to be a

-Version 3.5
-===========
+## Version 3.5
+
+### Upgrade Notes
 
 - RomWBW is now more strict with respect to hard disk partition
   tables.  If your hard disk media was created using any of the
   pre-built disk image files, this will **not** affect you.  Otherwise,
   you may find you are unable to access slices beyond the first
-  slice.  If so, use FDISK80 to reset the partition table on the
+  slice.  If so, use `FDISK80` to reset the partition table on the
   disk.  This will restore normal access to all slices.  **Only** do
   this if you are having an issue.

+### New Features
+
+- RC2014 Front Panel and LCD Screen support.
+
+- Console "takeover" support at Boot Loader prompt by pressing the

+
+- Cowgol disk image based on the work of Ladislau Szilagyi.
+
+- TMS video is automatically reset after an OS warm boot which
+  allows OS to recover from applications that reprogram the TMS
+  video display controller.
+
+- Implemented "application" RAM banks that can be discovered bia
+  the HBIOS API.

+- Documentation improvements (Mark Pruden), including:
+
