What's New in UD6 3.1 (UD6 and later)

Builds of UD6 2.1.05 starting with include features designated as 'UD6 3.1'.

That probably sounds a bit confusing. It sounds confusing because it is. It's to do with the way we develop the UD6 software internally.

In order to ensure that new releases of UD6 remain as 'backwards compatible' as possible, we develop each new feature (disabled by default) within the 'old' release - in this case we are developing the 'new' 3.1 features inside the old 2.1.05 release.

When we release the first 'beta' of UD6 3.1 it will be identical to the last release of 2.1.05, except the 'default' settings will have changed.

UD6 3.1 is the first release where we are opening this up to customers. The process has already been going for a few years in fact: we first introduced the UD6 3.1 XML file format a few years ago with the UD6IDE Eclipse Based IDE for Uniface. But now we are going further and explaining all the new options and what we currently expect the 'default' 3.1 settings will be.

We will continue to build separate UD6 2.1.05 and 3.1 releases, however after the first beta they may diverge.

If you are currently using a version of UD6 prior to 2.1.05 then we strongly recommend you first upgrade to UD6 or later before upgrading to UD6 3.1.

New to UD6 3.1 are:

Note: *SSE Optimisations are not currently available for testing.
^Set UD6 Parameters in Registry/UD6 params GUI not currently available for testing.

Recommendations for new users:

New users should use UD6 3.1 (or UD6 or later) as your first installation. Use the 'recommended settings' above.

Recommendations for existing users:

Existing users should plan to upgrade to UD6 3.1 as soon as possible. If you cannot upgrade immediately, then you should use UD6 or later until you are able to migrate to 3.1.

If you intend to upgrade to Uniface 10 at any point in the future, you should strongly consider changing to the new default file format first. You can elect to remain with the old file format, but some new UD6 3.1 features rely on the new file formats.

To upgrade to the new file formats you must:


When you export the Uniface 9 repository. for this to work correctly you must specify some additional settings in your ASN file USYS$UD6_PARAMS. These settings are:

USYS$UD6_PARAMS=performance 239, etc etc
