3.6.1 (2024-02-26)

  • Add support for Python 3.12.

3.6.0 (2023-06-16)

  • Drop support for Python 2.7 and 3.6.

3.5.0 (2020-10-11)

  • Do not require mock for the test suite on Python 3; use unittest.mock instead.

  • 100% test coverage for each version of Python rather than combined, using coverage-python-version.

  • Add the optional extra_node_attrs parameter to show_backrefs and show_backrefs

  • Fix IPython/Jupyter inline graph support code that would kick in even if you explicitly passed a filename=’foo.png’ argument to show_refs/show_backrefs. See issue 47.

  • Add support for Python 3.8.

  • Drop support for Python 3.5.

3.4.1 (2019-04-23)

  • Add support for Python 3.7.

3.2.0 (2017-12-20)

3.1.2 (2017-11-27)

  • Correct UTF-8 mojibake in the changelog and switch all links to HTTPS.

3.1.1 (2017-10-30)

  • Add support for Python 3.6.

  • Replace bare except: in safe_repr() with except Exception:.

3.1.0 (2016-12-07)

  • Support displaying graphs inline in IPython/Jupyter notebooks (issue 28 <>).

3.0.1 (2016-09-17)

  • The file argument of show_most_common_types() and show_growth() now defaults to None instead of sys.stdout. None is interpreted to be the same as sys.stdout, which means the right stdout will be used if you change it at runtime (which happens, in doctests).

3.0.0 (2016-04-13)

  • show_most_common_types() and show_growth() now accept a file argument if you want to redirect the output elsewhere.

    Fixes issue 24. Contributed by “d-sun-d”.

  • Don’t trust __class__ to be accurate and __name__ to be a string. Fixes errors in some convoluted corner cases when mocks are involved.

    Contributed by Andrew Shannon Brown in PR 26.

  • Drop support for Python 2.4, 2.5, and 2.6.

  • Drop support for Python 3.1 and 3.2.

  • Add support for Python 3.5.

2.0.1 (2015-07-28)

2.0.0 (2015-04-18)

  • show_refs() and show_backrefs() now accept a file-like object (via the new output argument) as an alternative to a filename.

  • Made internal helper methods private. This includes find_chain, show_graph, obj_node_id, obj_label, quote, long_typename, safe_repr, short_repr, gradient, edge_label, and _program_in_path.

  • Correctly determine the name of old-style classes in count(), by_type(), and graph drawing functions.

    Fixes issue 16. Contributed by Mike Lambert.

1.8.1 (2014-05-15)

  • Do not expect file objects to have an encoding attribute. Makes objgraph compatible with Eventlet’s monkey-patching.

    Fixes issue 6. Contributed by Jakub Stasiak.

1.8.0 (2014-02-13)

1.7.2 (2012-10-23)

  • Bugfix: sdist was broken on Python 2.7 (UnicodeDecodeError in tarfile).

  • The filename argument for show_refs() and show_backrefs() now allows arbitrary image formats, not just PNG. Patch by Riccardo Murri.

  • Temporary dot files are now named objgraph-*.dot instead of tmp*.dot.

  • Python 3.3 support: no code changes, but some tests started failing because the new and improved dictionary implementation no longer holds references to str objects used as dict keys.

  • Added a tox.ini for convenient multi-Python testing.

1.7.1 (2011-12-11)

  • Bugfix: non-ASCII characters in object representations would break graph generation on Python 3.x, in some locales (e.g. with LC_ALL=C). Reported and fixed by Stefano Rivera.

  • Bugfix: was broken on Python 3.x

  • Bugfix: dot.exe/xdot.exe were not found on Windows (LP#767239).

  • Documentation updates: document the forgotten find_ref_chain(), update show_chain() prototype.

1.7.0 (2011-03-11)

1.6.0 (2010-12-18)

  • Python 3 support, thanks to Stefano Rivera (fixes LP#687601).

  • Removed weird weakref special-casing.

1.5.1 (2010-12-09)

  • Avoid test failures in uncollectable-garbage.txt (fixes LP#686731).

  • Added HACKING.txt (later renamed to HACKING.rst).

1.5.0 (2010-12-05)

1.4.0 (2010-11-03)

  • Compatibility with Python 2.4 and 2.5 (tempfile.NamedTemporaryFile has no delete argument).

  • New function: most_common_types().

1.3.1 (2010-07-17)

  • Rebuild an sdist with no missing files (fixes LP#606604).

  • Added and a Makefile to check that sdist generates source distributions with no files missing.

1.3 (2010-07-13)

  • Highlight objects with a __del__ method.

  • Fixes LP#483411: suggest always passing [obj] to show_refs(), show_backrefs(), since obj might be a list/tuple.

  • Fixes LP#514422: show_refs(), show_backrefs() don’t create files in the current working directory any more. Instead they accept a filename argument, which can be a .dot file or a .png file. If None or not specified, those functions will try to spawn xdot as before.

  • New extra_info argument to graph-generating functions (patch by Thouis Jones, LP#558914).

  • should work with distutils now (LP#604430, thanks to Randy Heydon).

1.2 (2009-03-25)

  • Project website, public source repository, uploaded to PyPI.

  • No code changes.

1.1 (2008-09-10)
