2.6.1 (2024-04-12)

  • This release includes no source code changes. The only changes are to the release workflow.
  • Binary wheels are now built on Linux for aarch64. Pull request by Kevin Park. GitHub #160.
  • Binary wheels are now built on macOS for Apple silicon. Requested by Kevin Park. GitHub #152.

2.6.0 (2024-03-19)

  • Added type annotations for instance variables on Metadata
  • Updated type stubs for maxminddb.extension.
  • setuptools is no longer listed as a runtime dependency. Pull request by Lewis Collard. GitHub #155.

2.5.2 (2024-01-09)

  • The vendored libmaxminddb version was updated to 1.9.0. This fixes an issue when reading databases with a search tree exceeding 2 GB. Reported by Sami Salonen. GitHub #146.

2.5.1 (2023-11-09)

  • This is a re-release of 2.5.0 to address missing files from the sdist. Reported by Lumír 'Frenzy' Balhar. GitHub #132.

2.5.0 (2023-11-08)

  • IMPORTANT: Python 3.8 or greater is required. If you are using an older version, please use an earlier release.
  • Windows is now supported by the C extension.
  • The Reader class now implements the __iter__ method. This will return an iterator that iterates over all records in the database, excluding repeated aliased of the IPv4 network. Requested by Jean-Baptiste Braun and others. GitHub #23.
  • The multiprocessing test now explicitly uses fork. This allows it to run successfully on macOS. Pull request by Theodore Ni. GitHub #116.
  • A vendored copy of libmaxminddb will now be used by default when building the extension. If you wish to continue using the system shared library, you may set the MAXMINDDB_USE_SYSTEM_LIBMAXMINDDB environment variable to a true value when building the extension.
  • The C extension now builds on Python 3.13.
  • The C extension will now be built for PyPy.

2.4.0 (2023-06-28)

  • Package metadata was migrated from setup.py to setup.cfg. GitHub #113.
  • The C extension now decrements the reference count on an object containing the database filename after its use in an error message rather than before. Pull request by Lumír 'Frenzy' Balhar. GitHub #114.

2.3.0 (2023-05-09)

  • IMPORTANT: Python 3.7 or greater is required. If you are using an older version, please use an earlier release.
  • distutils is no longer used for building the C extension.
  • Missing Py_INCREF was added to module initialization for the C extension. Pull request by R. Christian McDonald. GitHub #106.

2.2.0 (2021-09-24)

  • The return type for maxminddb.open_database() has been simplified to be just the Reader class as opposed to a union of that with the extension class. This is done by casting the extension to Reader. The extension class has the same public API as the pure Python implementation. This simplifies type checking for users of this library. The Reader class is exposed as maxminddb.Reader. Pull request by wouter bolsterlee. GitHub #88.
  • maxminddb.__all__ is now set to define a public API. Pull request by wouter bolsterlee. GitHub #88.
  • Fix minor regression in repr output of maxminddb.reader.Metadata in 2.1.0.

2.1.0 (2021-09-18)

  • The C extension now correctly supports objects that implement the os.PathLike interface.
  • When opening a database fails due to an access issue, the correct OSError subclass will now be thrown.
  • The Metadata class object is now available from the C extension module as maxminddb.extension.Metadata rather than maxminddb.extension.extension.
  • Type stubs have been added for maxminddb.extension.

2.0.3 (2020-10-16)

  • The 2.0.0 release unintentionally required Python to be compiled with mmap support for the module to work. mmap is now optional again. Reported by john-heasman-cg. GitHub #76.

2.0.2 (2020-07-28)

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

2.0.1 (2020-07-22)

  • Fix minimum required python version in setup.py. Pull request by Boros Gábor. GitHub #69 & #70.

2.0.0 (2020-07-21)

  • IMPORTANT: Python 3.6 or greater is required. If you are using an older version, please use a 1.x.x release.
  • Type hints have been added.

1.5.4 (2020-05-05)

  • 1.5.3 was missing a test database. This release adds the test file. There are no other changes. Reported by Lumír 'Frenzy' Balhar. GitHub #60.

1.5.3 (2020-05-04)

  • Fix a segfault when decoding a database with a corrupt data section. Reported by Robert Scott. GitHub #58.

1.5.2 (2019-12-20)

  • Minor performance improvements in the pure Python reader.

1.5.1 (2019-09-27)

  • Fix a possible segfault due to not correctly incrementing the reference on a returned object.

1.5.0 (2019-09-27)

  • Python 3.3 and 3.4 are no longer supported.
  • The extension source directory was moved to prevent an ImportWarning when importing the module on Python 2 with -Wdefault set. Reported by David Szotten and Craig de Stigter. GitHub #31.
  • The get method now accepts ipaddress.IPv4Address and ipaddress.IPv6Address objects in addition to strings. This works with both the pure Python implementation as well as the extension. Based on a pull request #48 by Eric Pruitt. GitHub #50.
  • A new method, get_with_prefix_len, was added. This method returns a tuple containing the record and the prefix length.

1.4.1 (2018-06-22)

  • Fix test failure on Python 3.7. Reported by Carl George. GitHub #35.

1.4.0 (2018-05-25)

  • IMPORTANT: Previously, the pure Python reader would allow ipaddress.IPv4Address and ipaddress.IPv6Address objects when calling .get(). This would fail with the C extension. The fact that these objects worked at all was an implementation detail and has varied with different releases. This release makes the pure Python implementation consistent with the extension. A TypeError will now be thrown if you attempt to use these types with either the pure Python implementation or the extension. The IP address passed to .get() should be a string type.
  • Fix issue where incorrect size was used when unpacking some types with the pure Python reader. Reported by Lee Symes. GitHub #30.
  • You may now pass in the database via a file descriptor rather than a file name when creating a new maxminddb.Reader object using MODE_FD. This will read the database from the file descriptor into memory. Pull request by nkinkade. GitHub #33.

1.3.0 (2017-03-13)

  • maxminddb.Reader and the C extension now support being used in a context manager. Pull request by Joakim Uddholm. GitHub #21 & #28.
  • Provide a more useful error message when MODE_MMAP_EXT is requested but the C extension is not available.

1.2.3 (2017-01-11)

  • Improve compatibility with other Python 2 ipaddress backports. Although ipaddress is highly recommended, py2-ipaddress and backport_ipaddress should now work. Incompatibility reported by John Zadroga on geoip2 GitHub issue #41.

1.2.2 (2016-11-21)

  • Fix to the classifiers in setup.py. No code changes.

1.2.1 (2016-06-10)

  • This module now uses the ipaddress module for Python 2 rather than the ipaddr module. Users should notice no behavior change beyond the change in dependencies.
  • Removed requirements.txt from MANIFEST.in in order to stop warning during installation.
  • Added missing test data.

1.2.0 (2015-04-07)

  • Previously if MODE_FILE was used and the database was loaded before forking, the parent and children would use the same file table entry without locking causing errors reading the database due to the offset being changed by other processes. In MODE_FILE, the reader will now use os.pread when available and a lock when os.pread is not available (e.g., Python 2). If you are using MODE_FILE on a Python without os.pread, it is recommended that you open the database after forking to reduce resource contention.
  • The Metadata class now overloads __repr__ to provide a useful representation of the contents when debugging.
  • An InvalidDatabaseError will now be thrown if the data type read from the database is invalid. Previously a KeyError was thrown.

1.1.1 (2014-12-10)

  • On Python 3 there was a potential issue where open_database with MODE_AUTO would try to use the C extension when it was not available. This could cause the function to fail rather than falling back to a pure Python mode.

1.1.0 (2014-12-09)

  • The pure Python reader now supports an optional file and memory mode in addition to the existing memory-map mode. If your Python does not provide the mmap module, the file mode will be used by default.
  • The preferred method for opening a database is now the open_database function in maxminddb. This function now takes an optional read mode.
  • The C extension no longer creates its own InvalidDatabaseError class and instead uses the one defined in maxminddb.errors.

1.0.0 (2014-09-22)

  • First production release.
  • Two potential C extension issues discovered by Coverity were fixed:
    • There was a small resource leak that occurred when the system ran out of memory.
    • There was a theoretical null pointer issue that would occur only if libmaxminddb returned invalid data.

0.3.3 (2014-04-09)

  • Corrected initialization of objects in C extension and made the objects behave more similarly to their pure Python counterparts.

0.3.2 (2014-03-28)

  • Switched to Apache 2.0 license.
  • We now open the database file in read-only mode.
  • Minor code clean-up.

0.3.1 (2014-02-11)

  • Fixed packaging problem that caused import to fail.

0.3.0 (2014-02-11)

  • This release includes a pure Python implementation of the database reader. If libmaxminddb is not available or there are compilation issues, the module will fall-back to the pure Python implementation.
  • Minor changes were made to the exceptions of the C extension make them consistent with the pure Python implementation.

0.2.1 (2013-12-18)

  • Removed -Werror compiler flag as it was causing problems for some OS X users.

0.2.0 (2013-10-15)

  • Refactored code and fixed a memory leak when throwing an exception.

0.1.1 (2013-10-03)

  • Added MANIFEST.in

0.1.0 (2013-10-02)

  • Initial release
