v0.3.0

Added

• Dockerfile — multi-stage image (python:3.14-slim-trixie) that installs
  pinned dependencies from poetry.lock, builds the project wheel, and runs
  the server as a non-root user on port 9000
• .dockerignore and docker-compose.yml
• DOCKER.md — container build, configuration, and deployment guide
• Docker sections in README.md and SETUP.md
• Docker image build and container health-check steps to the release process
• keywords, license and classifiers metadata in pyproject.toml

Fixed

• Server failed to start with PackageNotFoundError because
  server.py looked up the pre-rename distribution name calculator-mcp
  instead of calculator-mcp-rubens

Changed

• Default server.host in the bundled config.yaml is now 0.0.0.0 so the
  server is reachable when running inside a container
• Added pylint 4.0.6+ and isort 8.0.1+ to the dev dependency group. They
  were previously expected to be installed globally via pipx, so a fresh
  clone could not run them after poetry install
• Bumped fastmcp minimum version from 3.2.0 to 3.4.7
• Bumped calculator-lib-rubens minimum version from 0.1.6 to 0.2.0
• Bumped py-key-value-aio minimum version from 0.4.4 to 0.4.5
• Bumped poetry-core build requirement from 2.3.1 to 2.4.1
• Bumped dev dependencies: black 26.5.1+, coverage 7.15.4+,
  pytest-asyncio 1.4.0+, mypy 1.20.2+

Removed

• Support for Python 3.12 and 3.13. requires-python is now >=3.14.0

v0.2.16

Changes

v0.2.12

Fix OAuth token exchange and add config-driven OAuth settings

Fixed

• OAuth token exchange failing with 401 due to CloudFront Lambda proxy rejecting Authorization: Basic header

Changed

• client.py: use config-driven token_dir and callback_port instead of hardcoded values
• client.py: request client_secret_post auth method during OAuth dynamic client registration
• client.py: skip health check for OAuth connections (hosted endpoint requires bearer token)

v0.2.11
