Hi all,
I wanted to mention some changes to the way UI data like min and max
are exposed in the Python API for custom properties (IDProperties),
since it might affect some addons or scripts. The idea was to simplify
the way UI data values were stored internally, and to take the
opportunity to provide a proper API for changing the values. Since the
patch [1] landed, the "_RNA_UI" group is not used to store these values
anymore, instead they are embedded in each property.
The release notes [2] and the patch go into more detail about the
changes in the API, but the basic pattern is retrieving a "manager"
object for a custom property's UI data with `id_properties_ui(name)`
and using its methods to change the data. Generally I don't expect most
scripts to have to change anything, but I already made the few changes
necessary in the addons repository with this commit [3].
Hopefully this isn't to disruptive to anyone.
Thanks!
Hans
