The table below specifies the more or less concrete short-to-mid-term plans:

Needless to say, all this is heavily subject to change.

The table below specifies the general plans for all applications, concerning important features, and availability on Windows, macOS and Linux.

macOS:
Apple has started deprecating 32-bit macOS applications, such as the four Mountain Utilities applications coming in 32-bit macOS editions (as specified in the table below).
Unfortunately, the Lazarus programming language, used to create these four applications, doesn't support macOS' 64-bit ("Cocoa") interface fully yet.
Therefore work on 64-bit editions of these applications can only start once Lazarus does support Cocoa fully.
It is uncertain when this will be the case: perhaps in 2019?

Windows:
All applications are available on Windows as installers. In the coming months the remaining ones that are currently only available as 32-bit installers will be upgraded to dual 32/64-bit installers (which automatically install the edition matching the operating system), and will also be made available as portable 32- and 64-bit editions.

As yet, D-5 Manager and Delta Framework are still behind the times in several respects, such as:

• MIDI I/O handling.
• They are still 'pre-mountainutilities.eu', thus link to the old Mountain Utilities web site.
• They don't provide advanced setup/desktop management yet.

However, these issues will be resolved in the upcoming releases too.
