 ## Unreleased
-
-### Breaking Changes
-
-- **Ariadne 1.x is required.** Supported versions are `ariadne>=1.0.1,<2.0.0` (the previous upper bound was `<0.30.0`). Upgrade Ariadne in applications that depend on this package before upgrading `ariadne-lambda`.
-- **`GraphQLLambdaHandler` subclasses `GraphQLHandlerBase`.** Ariadne 1.0 renamed the ASGI handler base class from `GraphQLHandler` to `GraphQLHandlerBase`; this package follows that API.
-- **Callable `context_value` must use `(request, data)`.** The old fallback for callables that only accepted `(request)` has been removed so behavior matches `GraphQLHandlerBase.get_context_for_request` in Ariadne 1.0.
-
-### Bug Fixes
-
-- **Lambda function URLs:** `Request.create_from_event` accepts HTTP API v2–style events used with **Lambda function URLs** when `queryStringParameters` is missing and `body` is omitted (previously could raise or mis-handle keys).
-
-### Improvements
-
-- Refine request parsing and GraphQL HTTP handling (Pydantic `Request` model, handler tests, and fixtures aligned with API Gateway v2 payloads).
-
-### CI/CD
-
-- Run tests on **Python 3.10–3.14** in a matrix; use **uv** (`astral-sh/setup-uv`) for dependency sync and running checks.
-- Refresh GitHub Actions (`actions/setup-python`, reusable **test** / **build** / **prepare_release** / **publish** workflows).
-- Replace older standalone workflows (`run_tests`, `code_quality`, `deploy`) with the modernized pipeline.
-
-### Build System
-
-- **Hatchling** remains the build backend; **uv** replaces the Hatch CLI for environments, tests, lint, and builds (`uv sync`, `uv run`, `uv build`).
-- Expanded `pyproject.toml` metadata, optional extras for dev/test/types (including **ruff** and **git-cliff** in `dev`), and **git-cliff** (`cliff.toml`) for release notes.
-- Add a **justfile** with common `uv run` targets (`lint`, `test`, `check`, changelog helpers).
-- Disable coverage **`fail_under`** until the test suite is expanded (previously targeted 90%).
-- Add **`pip`** to the `dev` optional extra for edge cases where `pip` is invoked alongside uv.
-- Add **`uv.lock`** for reproducible local and CI installs.
-
-### Documentation
-
-- Declare support for Python 3.10–3.14 in project metadata; update README contact email.
-
-### Testing
-
-- Add API Gateway v2 **Lambda function URL** sample payload and tests; extend HTTP handler and schema tests alongside the refactors above.
