What is OpenImageIO?
Every image reader is now assumed hostile, and the fuzzer proves it monthly
OpenImageIO ships on a monthly rhythm, releasing the current 3.1 line and the explicitly obsolete 3.0 line in tandem within minutes of each other. The dominant work is defensive: guarding pnm, jpeg-xl, dicom, cineon, dpx, fits and iff readers against corrupt or hostile files, with a CVE fixed in cineon bit-depth validation and a new limits:resolution attribute capping per-dimension image size against decompression bombs. libFuzzer-based fuzzing infrastructure for format readers landed in August.
What is Zeroheight?
Design system documentation making itself the constraint on AI-generated UI
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.

Every image reader is now assumed hostile, and the fuzzer proves it monthly
◆ Current state
OpenImageIO ships on a monthly rhythm, releasing the current 3.1 line and the explicitly obsolete 3.0 line in tandem within minutes of each other. The dominant work is defensive: guarding pnm, jpeg-xl, dicom, cineon, dpx, fits and iff readers against corrupt or hostile files, with a CVE fixed in cineon bit-depth validation and a new limits:resolution attribute capping per-dimension image size against decompression bombs. libFuzzer-based fuzzing infrastructure for format readers landed in August.
◆ Where it's heading
The project is institutionalizing the hardening rather than reacting to individual reports — building fuzzing into the repo, clarifying what qualifies as a vulnerability in its security policy, and adding a global attribute that lets applications set their own limits. Alongside that, oiiotool keeps gaining ergonomics, and genuinely new capability is being gated behind an explicit --experimental flag: the FLIP perceptual difference metric and a standalone GPU texture system prototype that deliberately does not touch the core library.
◆ Prediction
With 3.2 stated as roughly two months out and 3.0 support ending shortly after, expect the next releases to focus on that transition while the fuzzing infrastructure keeps producing reader fixes.

Design system documentation making itself the constraint on AI-generated UI
◆ Current state
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.
◆ Where it's heading
zeroheight's problem has always been that documentation nobody opens does not govern anything. All three releases attack that from different sides: bring the docs to where people already are (Slack, Teams), let them be asked instead of read (Assistant), and inject them into the tool that generates UI (Figma Make). The last is the most consequential, because it changes documentation from a reference into an input.
◆ Prediction
Expect connectors for further AI generation surfaces beyond Figma Make, since the Figma Make integration establishes the pattern of design system guidance as generation context rather than as a page someone consults.
