The biggest feature of this new release is a text editor: EDIT.BIN.
Unfortunately it's very basic (like notepad) and you have to convert your dos files to the unix style format using the dos2unix command on a linux box, or use something similar.

Changelog:

# New program: EDIT.BIN -- a full-screen text editor (currently
limited to Unix-formatted text files)

# README.TXT is no longer copied to the disk images; instead,
programs/sample.txt is added for use in EDIT.BIN

# CLI now includes CAT command to display a file: 'CAT FOO.TXT'

# Music keyboard (KEYBOARD.BIN) given new interface to show a visual
representation of a music keyboard

# os_write_file now removes an older version of the specified file, if
it exists, before performing the write operation

# CLI code (source/features/cli.asm) cleaned up -- split into sections
with fewer local labels

# os_string_parse call is now accessible to external programs

# Disk calls now convert a filename to uppercase automatically, so
there's no need for the calling code to do it

# API version bumped to 11
