5.3.0

• The version is now retrieved from package metadata at runtime using
  importlib.metadata. This reduces the chance of version inconsistencies
  during releases.
• The async client now builds its Authorization header with
  aiohttp.encode_basic_auth() instead of the aiohttp.BasicAuth /
  auth= parameter, which are deprecated as of aiohttp 3.14.0. As a result,
  the minimum required aiohttp version is now 3.14.0.
• A new residential attribute has been added to
  geoip2.records.Anonymizer. This is a geoip2.records.AnonymizerFeed
  object providing residential proxy data for the network and contains the
  following fields: confidence, network_last_seen, and
  provider_name. This attribute may be populated even when no other
  anonymizer attributes are set, so the anonymizer object may now
  contain only this attribute.
