+* This PR adds a new config variable called `error_on_missing_variant_requires` that controls what happens when
+ a variant lists missing packages in its requirements.
+
+ By default, it is True and will continue the existing behaviour of erroring when it encounters
+ a variant with missing packages in its list of requirements. This means that if the first variant
+ encounters a missing package in its request, it will not continue even if the second variant can resolve.
+
+ If it is disabled, it will print to stderr, treat the current phase as failed and continue on to the next phase.
+ If all variants fail, it will be the same as if no variants could resolve.
+
+ This feature was added by [dgovil](https://github.com/dgovil) in [\#1550](https://github.com/AcademySoftwareFoundation/rez/pull/1550).
