Django MongoDB Backend 5.2.2 has been released!

[Noah_Stapp]

We are pleased to announce that Django MongoDB Backend 5.2.2 is now available!

New features

• :class:.SearchIndex’s new field_mappings, analyzer, and search_analyzer arguments allow creating more complex indexes.

Bug fixes

• Fixed a KeyError crash when loading models with EmbeddedModel fields that use a database converter, if the field isn’t present in the data (e.g. data not written by Django, or after a field was added to an existing EmbeddedModel).
• Made EmbeddedModel fields respect :attr:~django.db.models.Field.db_column.
• Corrected the search index type of EmbeddedModelField and PolymorphicEmbeddedModelField from embeddedDocuments to document.
• Fixed transaction.atomic() crash if the database connection isn’t initialized.

Performance improvements

• Continued the query optimization work started in 5.2.1, making queries avoid using $expr where possible, so that they can use indexes.

Deprecated features

• django_mongodb_backend.utils.parse_uri() is deprecated in favor of putting the connection string in DATABASES["HOST"]. See :ref:the deprecation timeline <parse-uri-deprecation> for upgrade instructions.

Enjoy the release and if you experience any issues please report them!
