2.114.0 (2023-11-23)

Source | Diff

This is mainly a maintenance release. It will probably the last release in the 2.x series. We might issue a 2.115.0, but this isn't guaranteed.

Rez installations now only support Python 3.7+. It is important to note that the API
can still be used with Python 2.7+ but this will be dropped in 3.0.0.

Features

• New environment variable REZ_LOG_DEPRECATION_WARNINGS that will force
  all deprecation warnings to be printed, ignoring PYTHONWARNINGS and custom
  warning filters. Note that enabling this will forcefully load every
  configuration file instead of loading them lazilly.

• 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 in #1550.

We decided to deprecated some things that have been "deprecated" for a while but were never
officially marked as deprecated. We have prepared
a guide
