v1.10.0a1 (2022-08-22)¶
Pre-release, see the GitHub release for details.
v1.9.2 (2022-08-11)¶
Revert Breaking Change: v1.9.1 introduced a breaking change where model fields were
deep copied by default, this release reverts the default behaviour to match v1.9.0 and before,
while also allow deep-copy behaviour via copy_on_model_validation = 'deep'
. See #4092 for more information.
- Allow for shallow copies of model fields,
Config.copy_on_model_validation
is now a str which must be'none'
,'deep'
, or'shallow'
corresponding to not copying, deep copy & shallow copy; default'shallow'

__root__
