Changes Made
Section titled “Changes Made”1. PydanticAI — Updated to v1.84.1
Section titled “1. PydanticAI — Updated to v1.84.1”Files modified:
PydanticAI_Guide/pydantic_ai_comprehensive_guide.mdPydanticAI_Guide/README.md
Previous documented version: 1.84.0 (April 17, 2026)
New version: 1.84.1 (April 18, 2026)
v1.84.1 — Documented for the first time
Section titled “v1.84.1 — Documented for the first time”| Change | Detail |
|---|---|
| Skip tool hooks for internal output tools | Tool before_call / after_call hooks are no longer invoked for the framework-internal output-capture tool, preventing spurious hook executions |
Dict-shaped validated args to hooks for single-BaseModel tools | When a tool’s parameter signature is a single Pydantic BaseModel, hooks now consistently receive a dict representation of the validated model, matching the multi-parameter behaviour |
