Sage 4.0 was released on FIXME. For the official, comprehensive release note, please refer to [[http://www.sagemath.org/src/announce/sage-4.0.txt|sage-4.0.txt]]. A nicely formatted version of this release tour can be found at FIXME. The following points are some of the foci of this release: * == Algebra == * Deprecate the {{{order()}}} method on elements of rings (John Palmieri) -- The method {{{order()}}} of the class {{{sage.structure.element.RingElement}}} is now deprecated and will be removed in a future release. For additive or multiplicative order, use the {{{additive_order}}} or {{{multiplicative_order}}} method respectively. * FIXME: summarize #6052 == Algebraic Geometry == * Various invariants for genus 2 hyperelliptic curves (Nick Alexander) -- The following invariants for genus 2 hyperelliptic curves are implemented in the module {{{sage/schemes/hyperelliptic_curves/hyperelliptic_g2_generic.py}}}: * the Clebsch invariants * the Igusa-Clebsch invariants * the absolute Igusa invariants == Basic Arithmetic == * FIXME: summarize #6036 * FIXME: summarize #6080 == Build == == Calculus == == Coercion == == Combinatorics == * FIXME: summarize #5502 * FIXME: summarize #5586 == Commutative Algebra == * FIXME: summarize #5576 * FIXME: summarize #5609 * FIXME: summarize #5566 == Distribution == == Doctest == == Documentation == == Geometry == == Graph Theory == * Graph colouring (Robert Miller) -- New method {{{coloring()}}} of the class {{{sage.graphs.graph.Graph}}} for obtaining the first (optimal) coloring found on a graph. Here are some examples on using this new method: {{{ sage: G = Graph("Fooba") sage: P = G.coloring() sage: G.plot(partition=P) sage: H = G.coloring(hex_colors=True) sage: G.plot(vertex_colors=H) }}} {{attachment:graph-colour-1.png}} {{attachment:graph-colour-2.png}} * FIXME: summarize #6066 * FIXME: summarize #3932 * FIXME: summarize #5940 * FIXME: summarize #6086 == Graphics == * FIXME: summarize #5249 == Group Theory == * FIXME: summarize #5664 * FIXME: summarize #5844 == Interfaces == * Viewing Sage objects with a PDF viewer (Nicolas Thiery) -- Implements the option {{{viewer="pdf"}}} for the command {{{view()}}} so that one can invoke this command in the form {{{view(object, viewer="pdf")}}} in order to view {{{object}}} using a PDF viewer. Typical uses of this new optional argument include: * You prefer to use a PDF viewer rather than a DVI viewer. * You want to view LaTeX snippets which are not displayed well in DVI viewers (e.g. graphics produced using tikzpicture). * Change name of Pari's {{{sum}}} function when imported (Craig Citro) -- When Pari's {{{sum}}} function is imported, it is renamed to {{{pari_sum}}} in order to avoid conflict Python's {{{sum}}} function. == Linear Algebra == * FIXME: summarize #5974 * FIXME: summarize #5557 * FIXME: summarize #5381 * FIXME: summarize #5554 == Miscellaneous == * Allow use of {{{pdflatex}}} instead of {{{latex}}} (John Palmieri) -- One can now use {{{pdflatex}}} instead of {{{latex}}} in two different ways: * Use a {{{%pdflatex}}} cell in a notebook; or * Call {{{latex.pdflatex(True)}}} after which any use of {{{latex}}} (in a {{{%latex}}} cell or using the {{{view}}} command) will use {{{pdflatex}}}. One visually appealing aspect of this is that if you have the most recent version of [[http://pgf.sourceforge.net|pgf]] installed, as well as the {{{tkz-graph}}} package, you can produce images like the following: {{attachment:pgf-graph.png}} * FIXME: summarize #5783 == Modular Forms == * FIXME: summarize #4337 * FIXME: summarize #4357 * FIXME: summarize #5262 * FIXME: summarize #5792 * FIXME: summarize #5796 * FIXME: summarize #6019 * FIXME: summarize #5924 == Notebook == == Number Theory == * FIXME: summarize #5250 * FIXME: summarize #6013 * FIXME: summarize #6008 * FIXME: summarize #6004 * FIXME: summarize #6059 * FIXME: summarize #6064 == Numerical == == Packages == * FIXME: summarize #4223 * FIXME: summarize #6031 * FIXME: summarize #5934 * FIXME: summarize #1338 * FIXME: summarize #6032 * FIXME: summarize #6024 == P-adics == * FIXME: summarize #5105 * FIXME: summarize #5236 == Quadratic Forms == * FIXME: summarize #6037 == Symbolics == == Topology == * Random simplicial complexes (John Palmieri) -- New method {{{RandomComplex()}}} in the module {{{sage/homology/examples.py}}} for producing a random {{{d}}}-dimensional simplicial complex on {{{n}}} vertices. Here's an example: {{{ sage: simplicial_complexes.RandomComplex(6,12) Simplicial complex with vertex set (0, 1, 2, 3, 4, 5, 6, 7) and facets {(0, 1, 2, 3, 4, 5, 6, 7)} }}} == User Interface == == Website / Wiki == |
