v2.1.1a

What's Changed

• [New] Implemented StreamingDataFrame.apply(expand=True) to produce multiple individual values based on the collection. [#246]

  Docs

• [Fix] Make "and" and "or" comparisons lazy in StreamingSeries [#248]
  In previous versions, code like sdf['a'] | sdf['b'] and sdf['a'] & sdf['b'] was always evaluating both sides of the expression, while usual and and or can evaluate the right side lazily.

• Various docs updates: #247 #250 #251
