In 2024, thanks to an investment from @sovereign.tech, we systematically collected compatibility data for 30 browser releases throughout the entire year. As a result, whenever browsers shipped new features, the data was already available on @mozdevnet.bsky.social, caniuse.com, and other projects.

In 2024, we cataloged web platform features, became a maintainer of the W3C WebDX github.com/web-platform... project, and made sure it syncs up nicely with browser-compat-data.

In 2024, we joined the W3C Security Web Application Guidelines Community Group (SWAG CG). We created and rewrote docs about XSS and CSP and will continue this work in 2025 to make sure we promote security best practices and help developers understand security threats and their mitigations.

In 2024, we identified missing reference pages for widely available features and created ~600 new pages on MDN Web Docs to fill this gap. We also continued to play an essential maintainer role by reviewing pull requests for mdn/content and mdn/browser-compat-data.
