What is Mentimeter?
Mentimeter keeps folding AI into the loop — now summarizing sessions after they end.
Mentimeter is an audience-engagement and interactive-presentation tool that has spent 2026 turning AI from an add-on into a default layer of the product. Its monthly update cadence is steady, and the through-line is AI touching more of the workflow: building presentations, suggesting questions, grouping live responses, and now summarizing outcomes. A parallel bet, Menti Pulse, is pushing the brand beyond one-off presentations toward recurring team sensing.
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.

Mentimeter
2.5DESIGN
Mentimeter keeps folding AI into the loop — now summarizing sessions after they end.
◆ Current state
Mentimeter is an audience-engagement and interactive-presentation tool that has spent 2026 turning AI from an add-on into a default layer of the product. Its monthly update cadence is steady, and the through-line is AI touching more of the workflow: building presentations, suggesting questions, grouping live responses, and now summarizing outcomes. A parallel bet, Menti Pulse, is pushing the brand beyond one-off presentations toward recurring team sensing.
◆ Where it's heading
Two vectors are compounding: AI is moving from creation-time assistance toward full-lifecycle coverage (pre-session build, in-session grouping, post-session takeaways), and Menti Pulse is an attempt to make Mentimeter a continuous engagement surface inside tools like Microsoft Teams rather than a per-meeting utility. The post-session AI takeaways close the last open gap in the meeting lifecycle.
◆ Prediction
Expect Mentimeter to keep pushing AI outward from the live session — likely deeper post-session analytics and cross-Menti trend summaries — while moving Menti Pulse from closed beta toward wider availability.
OpenImageIO

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.
