Sage is free and open software that supports research and teaching in algebra, geometry, number theory, cryptography, etc. Both the Sage development model and the technology in Sage itself are distinguished by an extremely strong emphasis on openness, community, cooperation, and collaboration: we are building the car, not reinventing the wheel.

This web page lists both bugs in Sage and ideas for features to add to Sage. Please help Sage development by posting extensive information about all bugs you know of or find in Sage here, no matter how trivial.

Formatting hint for bug reports

Please use the {{{ and }}} tags to add code snippets and Sage session transcripts. For example:

 {{{
  sage: 1 + 2
  3
 }}}

Display:

  sage: 1 + 2
  3

Moreover, use backticks `DiGraph` around names like DiGraph to avoid automatic hyperlink: DiGraph?.

Browse Open Issues and Review Some Patches!

Use various reports located at  http://trac.sagemath.org/sage_trac/report to browse open tickets. Of particular note, reviewing tickets should be a high priority, because these tickets are typically almost ready to close with little effort. This is accessible from any page in Trac, by the "View Tickets" button.

If you are logged in, one particularly useful report is  this one, which gives all open tickets you've somehow participated in.

Here are  the public bug reports from the notebook interface.
