Release Notes

Release 0.5.4

Release:0.5.4 Date:TBD

New Features

None

New Types

• datashape now supports a categorical type (#150).

Experimental Types

Warning

Experimental types are subject to change.

• Records can now be constructed with the new syntax: R['field0':type0, 'field1':type1, ...] where each slice object represents a field in the record. R acts as an alias for Record to make it more pleasant to construct these literal types (#186).

API Changes

• datashape no longer supports Python 2.6 (#189).

• datashape no longer support Python 3.3 (#191).

• The default repr of Mono subclass now prints out the slot names as keyword arguments next to their values (#188). For example

  Instead of

  >>> from datashape import Decimal
  >>> Decimal(precision=11, scale=2)
  Decimal(11, 2)
  

  we have

  >>> Decimal(precision=11, scale=2)
  Decimal(precision=11, scale=2)
  

• Fields are now always constructed with str in Record datashapes (#197).

Bug Fixes

• Makes the parser recognize null and void (#183).
• Cache the datashape hash value to avoid potentially expensive recomputation during memoization (#184).
• Fix discovery of strings that start with things that look like numbers (#190).
• Makes the parser recognize object (#193).
• Make string field names in Record types have the same string type (#200).
• Fix the reprs for Function objects (#194).

Miscellaneous

None
