Release 1.0.0

Reaching 1.0 primarily means that API stability has been reached so I don't expect to run into many new breaking changes.

New Features

• Added optional initial value for reduce (EntilZha#86)
• Added table of contents to readme (EntilZha#88)
• Added data interchange tutorial with pandas (https://github.com/EntilZha/PyFunctional/blob/master/examples/PyFunctional-pandas-tutorial.ipynb)
• Implemented itertools.starmap as Sequence.starmap and Sequence.smap (EntilZha#90)
• Added interface to csv.DictReader via seq.csv_dict_reader (EntilZha#92)
• Improved _html_repr_, show and tabulate by auto detecting named tuples as column names (EntilZha#91)
• Improved _html_repr_ and show to tell the user 10 of N rows are being shown if there are more than 10 rows (EntilZha#94)

Dependencies and Supported Python Versions

• Bumped version dependencies (EntilZha#89)
• Added Python 3.6 via Travis CI testing

Release 0.8.0

New Features

• Implemented pretty html repr for Jupyter
• Implemented proper parsing of pandas DataFrames
• Detect when its possible to pretty print a table and do so
• list/to_list have a parameter n to limit number of results

Bug Fixes

• Fixed bug where grouped unnecessarily forces precomputation of sequence
• Remove package installations from default requirements that sometimes break installation on barebones systems in python 2.7

Release 0.7.0

New Features

• Auto parallelization by using pseq instead of seq. Details at EntilZha#47
• Parallel functions: map, select, filter, filter_not, where, flatten, and flat_map
• Compressed file IO support for gzip/lzma/bz2 as detailed at EntilZha#54
• Cartesian product from itertools.product implemented as Pipeline.cartesian
• Website at pyfunctional.pedro.ai and docs at docs.pyfunctional.pedro.ai

Bug Fixes

• No option for encoding in to_json EntilZha#70

Internal Changes

• Pinned versions of all dependencies

Contributors

• Thanks to versae for implementing most of the pseq feature!
• Thanks to ChuyuHsu for implemented large parts of the compression feature!

Release 0.6.0

New Features

• Added support for reading to and from SQLite databases
• Change project name to PyFunctional from ScalaFunctional
• Added to_pandas call integration

Internal Changes

• Changed code quality check service

Release 0.5.0

New Features

• Added delimiter option on to_file
• Sequence.sliding to create a sliding window from a list of elements

Internal Changes

• Changed all relative imports to absolute imports with __future__.absolute_import

Bug Fixes

• Fixed case where _wrap is changing named tuples to arrays when it should preserve them
• Fixed documentation on to_file which incorrectly copied from seq.open delimiter parameter
• Fixed Sequence.zip_with_index behavior. used to mimic enumerate by zipping on the left size while scala and spark do zip on the right side. This introduces different behavior and more flexible behavior in combination with enumerate A start parameter was also added like in enumerate

Release 0.4.1

Fix python 3 build error due to wheel installation of enum34. Package no longer depends on enum34

Release 0.4.0
