2.0.0 (5/1/17)

This is a major release that adds the new Series classes but importantly breaks the DataFrame API by renaming the “sorted” argument with “sort” and all associated properties and setters. This is to remove the naming conflict with the builtin sorted function

  • Added new Series class
  • Added new ViewSeries class
  • Fix performance bug in the select_index() function in DataFrame
  • Change sorted argument on DataFrame to sort
  • Change sorted DataFrame property and setters to sort

2.1.0 (5/12/17)

Another potentially backwards incompatible change by making the .index properties to be a view and no longer a copy.

DataFrame

  • Changes the DataFrame.index to return a view and not a copy.
  • New get_slice() method for sorted DataFrames
  • Changed [] on sort DataFrames to use get_slice() on slices
  • New set_location() method for DataFrame
  • New append_rows() method for DataFrame

Series

  • Changed the Series.data and Series.index properties to return a view and not a copy
  • New get_slice() method for sorted Series
  • New set_location() method
  • New append_rows() method for Series

2.1.1 (5/15/17)

  • Added columns=None default to get_column() on DataFrame
  • Fix bug in get_slice for empty DataFrames
  • Fix bug in DataFrame append for empty DataFrames

2.1.2 (5/20/17)

  • Added delete_all_rows() to DataFrame
