v0.4.1

Fixed

• README version badges (PyPI, Python versions) could display a stale version or
  "not found" — their images were cached by GitHub's camo proxy at first render,
  before the package existed on PyPI. Appended cacheSeconds to the shields.io
  URLs to change the proxy cache key and force a fresh fetch.

Added

• Note under the badge row explaining that the version badges are cached images
  (shields.io and PyPI's own image proxy) that may briefly lag a fresh release,
  pointing to the release/tag, the PyPI page heading, and the server_info tool
  for the authoritative version.
