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

By Monday Jan 30, 2023 at 23:00 UTC, the Trac website is planned to be available again, but in public read-only mode only.
- Logins to the Trac website, whether by Trac account or by GitHub credentials, will no longer work.
- It will no longer be possible to use SSH to access the Trac git server. In particular, it will no longer be possible to push to the Trac git server.

Please help SageMath development by reporting bugs that you encounter, no matter how trivial.
If you need to open a ticket, please use the {{{ and }}} tags to add code snippets and SageMath session transcripts. For example:
| Markup | Displays as |
|---|---|
|
|
You can also use backticks (`) to demarcate inline code snippets, etc. This is useful around names like DiGraph to avoid an automatic wikilink (DiGraph), like so: `DiGraph`.
SageMath makes use of many upstream projects, which have their own bug tracking pages. A selection: Cython, fflas-ffpack, GAP, GCC (instructions), Givaro, JMol, LinBox, Maxima, Numpy, PARI/GP (instructions), Python, Singular.
Follow the Trac development timeline or active tickets by time, or view [other ticket reports].
Help by reviewing Tickets needing review (see checklist).
Catch up on Open tickets you've participated in or make a Custom query.
Contribute to the Release notes for the current development series by collaborative editing.
Explore the Open meta-tickets on larger tasks or topical pages on Algebra, Coding Theory, Combinatorics, Manifolds, Optimization, Polyhedral Geometry, Symbolics.
Discuss in sage-devel or one of our other development groups.
Our FAQ on contributing to SageMath will take you to sections Working on tickets and Working with git in the Developer's Guide. Make sure you understand the review process, and the procedures for opening and closing tickets.
When opening a ticket to make a feature request or to plan a project, you may find our Feature request guidelines helpful.
After pushing a branch to a ticket, the ticket will show badges linking to results of automated tests that run on the patchbot and other tests that run on GitHub Actions.
Participate in or help organize Workshops and other activities, or contribute to the Sage community by answering questions.
You can also help maintain the Technical project infrastructure.
The list of over 600 account holders in Sage's Trac that was here is now merged to the contributors.xml through Github PR. The merged developers list is at SageMath developer world map.
