New in SAGE 3.2.2 (January 1st, 2009)

  • Algebra:
  • Division over integers (Robert Bradshaw) -- A much simpler and faster algorithm for the divisors function over integers. The new optimized code is faster than a similar integer divisor function in the version of PARI/GP that's bundled with Sage 3.2.1, as well as outperforming a similar integer divisor function found in the version of Magma that Sage 3.2.1 interfaces with.
  • Finite field operations (John Palmieri) -- A few methods for finite field elements including additive order, p-th power, and p-th root where p is the characteristic of the field.
  • Basic arithmetic:
  • Polynomials over a field (Burcin Erocal) -- Improving the user interface of polynomial classes.
  • Polynomial square roots (John Palmieri, Carl Witty) -- A method to test whether a polynomial is square over the field it is defined. If the polynomial is square, then the method has the option of returning a square root.
  • Build:
  • Improve sage -upgrade (William Stein, Michael Abshoff) -- The Sage upgrade command can now take an optional URL from which it will pull all spkg's, and this URL can be a Sage install. The upgrade command lists packages that will be upgraded before upgrading them, and autodownloads a new version of any spkg that hasn't successfully been installed before upgrading it.
  • Problematic CPU flags (William Stein, Michael Abshoff) -- Binary distributions of Sage for Linux (e.g. Ubuntu) may not work properly once installed. The following CPU flags are known to prevent Sage from running properly: sse, 3d, mmx, pni, and cmov.
  • Calculus:
  • Gamma and factorial functions (Mike Hansen, Burcin Erocal, Wilfried Huss) -- Symbolic gamma and factorial functions.
  • Update to sympy-0.6.3 (Ondrej Certik) -- Update to the latest upstream of SymPy (sympy-0.6.3), which is a Python library for symbolic mathematics. For more information about SymPy, please visit http://code.google.com/p/sympy/.
  • Numerical trigonometry (Robert Bradshaw) -- Optimized floating point evaluation of trigonometric functions such as sine and cosine. For example, numerical calculation of sine via _fast_float_ is now twice as fast as math.sin.
  • Floating point calculation (Robert Bradshaw) -- Changing the parsing code for numerical computation to use RDF, which is a better reflection of the underlying precision. For calculus expressions involving real numbers, redundant trailing zeros are removed.
  • Coercion:
  • Coercion API (Robert Bradshaw) -- Some simplification of the coercion interface.
  • Combinatorics:
  • Coding theory (David Joyner) -- Several changes in linear_codes.py which should speed up (and in some cases do:-) some coding theory computations considerably. It adds interfaces to Cython and C functions of Robert Miller, CJ Tjhal, and Jeffery Leon. Speed up of minimum_distance (for codes over GF(2) and GF(3)), the spectrum (=weight_distribution), and permutation_automorphism_group are expected and in most cases achieved. (Also a new function is_permutation_equivalent was added, which interfaces with Robert Miller's double coset partition refinement code.)
  • Incidence structures and block designs (David Joyner) -- Beginning of an incidence structure class and an implementation of some basic block design algorithms. A few functions require GAP's Design package (which is included in gap_packages-4.4.10_6.spkg) but calling GAP or GAP's Design was only done when the corresponding Sage functionality was missing. Robert Miller's recent code on computing the automorphism group of a non-linear binary code was used to implement the automorphism group of a block design.
  • Testing:
  • Added only_optional doctest option (William Stein) -- Added a new option sage -t -only_optional=component that allows one to run only the optional doctests that depend on a given component. Thus instead of much of the optional functionality of Sage being broken, it will now be much easier to automatically test it.

New in SAGE 3.0.6 (August 1st, 2008)

New in SAGE 3.0.5 (July 16th, 2008)
