Version
-------
The latest version of a supported dynamic UI syntax is 2.
This section is optional, the default version is set to 1.
Murano Juno and Kilo supports version 2. Version 1 is obsolete.
The syntax and format of dynamic UI definitions may change over time, so the
concept of `format versions` is introduced. Each UI definition file may contain
a top-level section called `Version` to indicate the minimum version of Murano
Dynamic UI platform which is capable to process it.
If the section is missing, the format version is assumed to be 1.
The version consists of two non-negative integer segments, separated by a dot,
i.e. has a form of `MAJOR.MINOR`.
Dynamic UI platforms having the same MAJOR version component are compatible:
i.e. the platform having the higher version may process UI definitions with
lower versions if their MAJOR segments are the same.
For example, Murano Dynamic UI platform of version 2.2 is able to process UI
definitions of versions 2.0, 2.1 and 2.2, but is unable to process 2.3, 3.0 or
1.9.
Currently the latest version of Dynamic UI platform is 2.0. It is incompatible
with UI definitions of Version 1, which were used in Murano releases before
Juno.
.. note::
Although the `Version` field is considered to be optional, it's default
value is 1.0, and thus such definitions can't be processed with the latest
Murano. So, be sure to specify the compatible format version when designing
your UI definitions.
