[pyup-bot]

This PR updates geoip2 from 2.7.0 to 4.8.1.

Changelog

4.8.0

++++++++++++++++++

* IMPORTANT: Python 3.8 or greater is required. If you are using an older
version, please use an earlier release.
* The ``is_anycast`` attribute was added to ``geoip2.record.Traits``.
This returns ``True`` if the IP address belongs to an
`anycast network <https://en.wikipedia.org/wiki/Anycast>`_.
This is available for the GeoIP2 Country, City Plus, and Insights web services
and the GeoIP2 Country, City, and Enterprise databases.

4.7.0

++++++++++++++++++

* IMPORTANT: Python 3.7 or greater is required. If you are using an older
version, please use an earlier release.

4.6.0

++++++++++++++++++

* The ``AddressNotFoundError`` class now has an ``ip_address`` attribute
with the lookup address and ``network`` property for the empty network
in the database containing the IP address. These are only available
when using a database, not the web service. Pull request by illes.
GitHub 130.

4.5.0

++++++++++++++++++

* Support for mobile country code (MCC) and mobile network codes (MNC) was
added for the GeoIP2 ISP and Enterprise databases as well as the GeoIP2
City and Insights web services. ``mobile_country_code`` and
``mobile_network_code`` attributes were added to ``geoip2.model.ISP``
for the GeoIP2 ISP database and ``geoip2.record.Traits`` for the
Enterprise database and the GeoIP2 City and Insights web services.
We expect this data to be available by late January, 2022.

4.4.0

++++++++++++++++++

* The public API on ``geoip2.database`` is now explicitly defined by
setting ``__all__``.
* The return type of the ``metadata()`` method on ``Reader`` is now
``maxminddb.reader.Metadata`` rather than a union type.

4.3.0

++++++++++++++++++

* Previously, the ``py.typed`` file was not being added to the source
distribution. It is now explicitly specified in the manifest.
* The type hints for the database file in the ``Reader`` constructor have
been expanded to match those specified by ``maxmindb.open_database``. In
particular, ``os.PathLike`` and ``IO`` have been added.
* Corrected the type hint for the ``metadata()`` method on ``Reader``. It
will return a ``maxminddb.extension.Metadata`` if the C extension is being
used.

4.2.0

++++++++++++++++++

* You may now set a proxy to use when making web service requests by passing
the ``proxy`` parameter to the ``AsyncClient`` or ``Client`` constructor.

4.1.0

++++++++++++++++++

* Added the ``is_residential_proxy`` attribute to ``geoip2.model.AnonymousIP``
and ``geoip2.record.Traits``.
* ``HTTPError`` now provides the decoded response content in the
``decoded_content`` attribute. Requested by Oleg Serbokryl. GitHub 95.

4.0.2

++++++++++++++++++

* Added ``py.typed`` file per PEP 561. Reported by Árni Már Jónsson.

4.0.1

++++++++++++++++++

* Re-release to fix bad reStructuredText in ``README.md``. No substantive
changes.

4.0.0

++++++++++++++++++

* IMPORTANT: Python 2.7 and 3.5 support has been dropped. Python 3.6 or greater
is required.
* Asyncio support has been added for web service requests. To make async
requests, use ``geoip.webservice.AsyncClient``.
* ``geoip.webservice.Client`` now provides a ``close()`` method and associated
context managers to be used in ``with`` statements.
* Type hints have been added.
* The attributes ``postal_code`` and ``postal_confidence`` have been removed
from ``geoip2.record.Location``. These would previously always be ``None``.
* ``user_id`` is no longer supported as a named argument for the constructor
on ``geoip2.webservice.Client``. Use ``account_id`` or a positional
parameter instead.
* For both ``Client`` and ``AsyncClient`` requests, the default timeout is
now 60 seconds.

3.0.0

++++++++++++++++++

* BREAKING CHANGE: The ``geoip2.record.*`` classes have been refactored to
improve performance. This refactoring may break classes that inherit from
them. The public API should otherwise be compatible.
* The ``network`` attribute was added to ``geoip2.record.Traits``,
``geoip2.model.AnonymousIP``, ``geoip2.model.ASN``,
``geoip2.model.ConnectionType``, ``geoip2.model.Domain``,
and ``geoip2.model.ISP``. This is an ``ipaddress.IPv4Network`` or an
``ipaddress.IPv6Network``. This is the largest network where all of the
fields besides ``ip_address`` have the same value. GitHub 79.
* Python 3.3 and 3.4 are no longer supported.
* Updated documentation of anonymizer attributes - ``is_anonymous_vpn`` and
``is_hosting_provider`` - to be more descriptive.
* Added support for the ``user_count`` trait for the GeoIP2 Precision webservice.
* Added the ``static_ip_score`` attribute to ``geoip2.record.Traits`` for
GeoIP2 Precision Insights. This is a float which indicates how static or dynamic
an IP address is.

2.9.0

++++++++++++++++++

* You may now pass in the database via a file descriptor rather than a file
name when creating a new ``geoip2.database.Reader`` object using ``MODE_FD``.
This will read the database from the file descriptor into memory. Pull
request by nkinkade. GitHub 53.

2.8.0

++++++++++++++++++

* Python 2.6 support has been dropped. Python 2.7+ or 3.3+ is now required.
* Renamed user ID to account ID in the code and added support for the new
``ACCOUNT_ID_REQUIRED`` AND ``ACCOUNT_ID_UNKNOWN`` error codes.
