Release Notes

Version 0.6

  • Python 2.6 support

  • Programmable typing
    • Allow users to add type inference for external code
  • Better NumPy type inference
    • outer, inner, dot, vdot, tensordot, nonzero, where, binary ufuncs + methods (reduce, accumulate, reduceat, outer)
  • Type based alias analysis
    • Support for strict aliasing
  • Much faster autojit dispatch when calling from Python

  • Faster numerical loops through data and stride pre-loading

  • Integral overflow and underflow checking for conversions from objects

  • Make Meta dependency optional

Version 0.5

  • SSA-based type inference
    • Allows variable reuse
    • Allow referring to variables before lexical definition
  • Support multiple comparisons

  • Support for template types

  • List comprehensions

  • Support for pointers

  • Many bug fixes

  • Added user documentation

Version 0.4

Version 0.3.2

  • Add support for object arithmetic (issue 56).
  • Bug fixes (issue 55).

Version 0.3

  • Changed default compilation approach to ast
  • Added support for cross-module linking
  • Added support for closures (can jit inner functions and return them) (see examples/closure.py)
  • Added support for dtype structures (can access elements of structure with attribute access) (see examples/structures.py)
  • Added support for extension types (numba classes) (see examples/numbaclasses.py)
  • Added support for general Python code (use nopython to raise an error if Python C-API is used to avoid unexpected slowness because of lack of implementation defaulting to generic Python)
  • Fixed many bugs
  • Added support to detect math operations.
  • Added with python and with nopython contexts
  • Added more examples

Many features need to be documented still. Look at examples and tests for more information.

Version 0.2

  • Added an ast approach to compilation
  • Removed d, f, i, b from numba namespace (use f8, f4, i4, b1)
  • Changed function to autojit2
  • Added autojit function to decorate calls to the function and use types of the variable to create compiled versions.
  • changed keyword arguments to jit and autojit functions to restype and argtypes to be consistent with ctypes module.
  • Added pycc – a python to shared library compiler
