# Release 2 note

You will find a description of the new features in the dmk/docs/dmk\_new\_features\_guide.html file. That is the initial starting point for a new / updated 2.x version. In this html file you will also find the link to this online documentation.

## OS support

Version 2.0 supports Linux. For other Unix, it is unsure if it works. On AIX, it worked with bash, but not with ksh.

In Version 2.1, the variable setting is completely rewritten. As a consequence of that, it is now possible to also run it on AIX with ksh.\
This version should support all Unix platforms.

In version 2.2, Windows support with cmd.exe and optionally poweshell is added.
