v1.0.0

• Switched from shelling out to Pip to using the internal Pip API natively via Python (closes #4 and closes #2), this change makes the previous ~1 minute operation now take ~1 second!
• Adds updated field indicating when the package was installed or updated (closes #5)
• The requires and required-by keys are now lists instead of comma separated strings, they also include the version the requirements are pinned to
• Using argparse instead of environment variable to specify path to site-packages
• Separated out code better into classes and additional functions
• 100% code coverage
• Converted classmethods to staticmethods

v0.5.0

• Removes pip version warnings from output
• Fixes local variable 'i' referenced before assignment error
• Matching pip command timeout by setting the subprocess timeout to 15 from 10 seconds
• Running pip commands in isolated mode which ignores custom configuration
• Running pip commands while skipping user input (if ever applicable)
• Small speed improvements were made by shifting logic around

v0.4.0

• Fixed reference of PIPPIN_PIP to PIP_PATH now that the package has been renamed
• Removed unused pip variables in favor of the constant PIP_PATH
• Updated documentation

v0.3.0

• Refactored Pippin from a shell script to a Python script
• Now retrieve the pip list as JSON
• Now retrieve the pip package details as RFC-compliant mail header format
• Now with Python, we shell out to pip and run the commands but retrieve the data as machine parseable instead of human readable and chopping it up after the fact
• Added unit tests, updated docs, added Makefile
• Changed name from Pippin to Pip Tree... stupid PyPi naming rules

v0.2.0

• Added the version number of the packages to the output
• Removed redundant file deletion to boost performance and decrease file manipulation calls
• Added documentation to better explain what each function does
• Small tweaks throughout

v0.1.0
