Changes

Version 0.2.0

Released March, 10th 2026

Breaking Changes

  • Pydantic v2 required — pydantic v1 is no longer supported. Upgrade your environment to pydantic>=2.0 before updating flask-jeroboam. Pydantic v2 continues to run v1-style @validator decorators with a deprecation warning, so most model code will work without changes.

  • Error response format updated to match pydantic v2 conventions (e.g. "Field required" / "missing" instead of "field required" / "value_error.missing").

Internal changes

  • Removed _compat.py pydantic v1 shim entirely

  • ViewArgument now inherits from pydantic v2 FieldInfo

  • SolvedArgument rebuilt around TypeAdapter — no more ModelField dependency

  • OpenAPI schema generation rewritten to use model_json_schema() and TypeAdapter.json_schema()

beta releases

The beta releases mark a turning point and the intention to outgrow Flask-Jeroboam’s initial internal use. The 0.1.0 version is primarily based on forking FastAPI and departs from the first naive implementation of alpha releases.

alpha releases

The alpha releases share a minimalist implementation of a tiny portion of the targetted features set. They are a packaged version of helper functions that I used to level up one particular flask project and are largely overfitted to this specific context.
