Django 4.2 LTS Adds psycopg 3 Support and Async Streaming

A new long-term support release

Django 4.2 was released on April 3, 2023 and designated a long-term support (LTS) release, meaning security and data-loss fixes will be applied for at least the next three years. Django said it would also receive fixes for crashing bugs, major functionality bugs in newly introduced features, and regressions for eight months, until December 2023.

psycopg 3 and database comments

For PostgreSQL users, Django 4.2 added support for psycopg version 3, the modernized successor to the widely used psycopg2 adapter. The release also introduced comments on columns and tables, letting models document their database schema directly.

More async surface area

Continuing Django's steady move toward async, 4.2 added support for asynchronous streaming responses, plus async interfaces for related managers and the Model class, expanding what can be done without dropping out of an async context.

Shifting the support window

With 4.2 out, Django 4.1 reached the end of mainstream support, with a final 4.1.8 bug-fix release, and Django 4.0 reached the end of extended support. As an LTS, 4.2 became the recommended target for teams that prioritize stability.
