What is Axure RP?
Axure wires its cloud canvas into the AI coding loop with an alpha MCP server
Axure has grown from its RP prototyping desktop app into Axure Cloud, a collaborative canvas with whiteboards and documents (out of beta in late 2025). Recent releases build out that cloud surface — libraries, custom templates, PDF export, tablet support — and have begun wiring in AI: document AI chat, and now an alpha MCP server that exposes whiteboard and document context to coding agents.
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.

Axure RP
2.5DESIGN
Axure wires its cloud canvas into the AI coding loop with an alpha MCP server
◆ Current state
Axure has grown from its RP prototyping desktop app into Axure Cloud, a collaborative canvas with whiteboards and documents (out of beta in late 2025). Recent releases build out that cloud surface — libraries, custom templates, PDF export, tablet support — and have begun wiring in AI: document AI chat, and now an alpha MCP server that exposes whiteboard and document context to coding agents.
◆ Where it's heading
The arc is turning Axure Cloud into a full collaborative design-and-docs workspace and connecting it to the AI toolchain. Libraries and templates standardize team assets; the MCP alpha and document AI chat point Axure at the design-to-code and agentic workflow. A meaningful share of the cadence is still stabilization and polish on the young cloud canvas.
◆ Prediction
Expect Axure to harden the MCP integration toward general availability and expand AI in documents and whiteboards, while rounding out cloud-canvas basics like custom colors, libraries, and export. The pull is toward being a context provider for AI coding tools, not only a prototyping app.
OpenImageIO
5.0DESIGN
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.
