Render mathematical expressions in Markdown

You can now use LaTeX style syntax to render math expressions within Markdown inline (using $ delimiters) or in blocks (using $$ delimiters).

Writing expressions as blocks

To add math as a multiline block displayed separately from surrounding text, start a new line and delimit the expression with two dollar symbols $$.

**The Cauchy-Schwarz Inequality**
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

Writing inline expressions

To include a math expression inline with your text, delimit the expression with a dollar symbol $.

This sentence uses `$` delimiters to show math inline:  $\sqrt{3x-1}+(1+x)^2$

Inline math markdown rendering

GitHub's math rendering capability uses MathJax; an open source, JavaScript-based display engine. MathJax supports a wide range of LaTeX macros and a number of useful accessibility extensions. For more information, see the MathJax documentation and the MathJax Accessibility Extensions documentation.

Some users have previously used a workaround to generate images of mathematical expressions through API requests. Images generated this way will remain viewable, but this technique will no longer work. Going forward, expressions should be written directly in Markdown using LaTeX syntax as described above.

Today's Changelog brings you the release of issue closed reasons, project deletion, and availability of the new side-panel.

🕵🏽‍♀️ Issue closed reasons

We announced a preview of issue closed reasons in March and today, we're releasing them to everyone. 🎉

Issue closed reasons help you communicate the why when closing an issue:

  • When closing, you can opt to close as complete (default option) or not-planned.
  • When filtering, adding a reason will allow you to filter down to the specific set you need with either reason:complete or reason:"not planned".
  • We have added a new state_reason attribute to our REST API, GraphQL API and webhooks. These are currently in preview and will be fully shipped in the upcoming week.

✂️ Delete projects you no longer need

While you've been able to close projects, we heard you loud and clear that it wasn't enough and we're now introducing the ability to fully delete a project. Keep your project lists tidy by deleting experimental or out-of-date projects that are no longer relevant to you and your team.


💥 Side-panel enabled for all projects (beta) users

In our last changelog, we introduced the projects side-panel as a feature preview users could choose to enable.

After seeing users flock to enable this feature and lots of great feedback in our side-panel discussion, we've decided to enable this feature by default.

Expect continued improvements in the side-panel experience over the next few months. ☀️

✨ Bug fixes & improvements

Other changes include:

  • Added a Copy link button to the sidebar for easier issue sharing and enabled keyboard shortcut (Space) to open the side panel.
  • Fixed various bugs around syncing information between the project and side panel.
  • Fixed full-height Markdown editor for drafts.
  • View and edit projects (beta) custom fields on GitHub Mobile.

You can now specify whether to display images for light or dark themes in Markdown, using the HTML <picture> element in combination with the prefers-color-scheme media feature.

For example:

  <source media="(prefers-color-scheme: dark)" srcset="">
  <img alt="Shows an illustrated sun in light color mode and a moon with stars in dark color mode." src="">

An animated screenshot of an issue comment that changes the color mode. The content shows an octobiwan in light and stormtroopocat in dark color mode.
