v1.5.1

• Don't raise an error if the directory used to store images already exists (#104, Augusto Zanellato).

v1.5.0: Last release supporting Python 2.

• Added an environment variable PANDOCFILTER_CLEANUP that when get_filename4code is used, temporary directory will be cleaned up automatically. See #88.
• examples/ is no longer included in the distribution (i.e. source distribution or binary wheels found on PyPI.) This should be a backward compatible change as examples/ is never exposed as a Python module, nor entry points.
• Added a couple of examples.
• See more in https://github.com/jgm/pandocfilters/compare/1.4.3...1.5.0.
