What is Air?
Air's asset library grew an agent, and the agent is learning to keep what it does.
Canvas has become the centre of the product. In the last three weeks it gained an agent that edits existing video rather than only generating new clips, two additional video models, the ability to save any completed workflow as a reusable skill, @ mentions that pull in board assets alongside Brand Kit colours, fonts and logos, and now in-image text translation across 33 languages. The library side kept moving too, with manual person tagging where facial recognition falls short, current-version share links, frame-level timeline zoom, and a batch of video features covering burned-in captions, transcript editing and sub-clipping.
What is libvips?
libvips 8.18 opened up UltraHDR and Oklab, then spent months closing memory bugs.
The feed tracks release candidates only. The 8.18 line added UltraHDR load and save, Oklab and Oklch colourspaces, raw camera loading through libraw, and gainmap plumbing through thumbnail and dzsave. The most recent tag, 8.18.3-rc1, is a different kind of release: roughly two dozen fixes for out-of-bounds reads, heap overflows and null dereferences across the jp2k, HEIF, Radiance, Magick and PPM loaders.

Air
8.8DESIGN
Air's asset library grew an agent, and the agent is learning to keep what it does.
◆ Current state
Canvas has become the centre of the product. In the last three weeks it gained an agent that edits existing video rather than only generating new clips, two additional video models, the ability to save any completed workflow as a reusable skill, @ mentions that pull in board assets alongside Brand Kit colours, fonts and logos, and now in-image text translation across 33 languages. The library side kept moving too, with manual person tagging where facial recognition falls short, current-version share links, frame-level timeline zoom, and a batch of video features covering burned-in captions, transcript editing and sub-clipping.
◆ Where it's heading
Air is converting a digital asset manager into a place where assets are produced and adapted, not just stored and approved. The skills feature is the pivot point: it turns one-off agent instructions into named, repeatable operations, which is how a creative team's conventions become part of the tool. Brand Kit entering the @ mention namespace points the same way — the agent is being given the brand's own vocabulary as addressable material, so generated work starts from house colours and logos rather than a generic prompt.
◆ Prediction
Expect skills to gain sharing or workspace-level scope, since a saved workflow is far more valuable to a team than to the person who recorded it. The translation and captioning work together suggests localisation is being assembled as a workflow rather than left as isolated features.
libvips
0.0DESIGN
libvips 8.18 opened up UltraHDR and Oklab, then spent months closing memory bugs.
◆ Current state
The feed tracks release candidates only. The 8.18 line added UltraHDR load and save, Oklab and Oklch colourspaces, raw camera loading through libraw, and gainmap plumbing through thumbnail and dzsave. The most recent tag, 8.18.3-rc1, is a different kind of release: roughly two dozen fixes for out-of-bounds reads, heap overflows and null dereferences across the jp2k, HEIF, Radiance, Magick and PPM loaders.
◆ Where it's heading
The arc runs from capability expansion to hardening. Having taken on more untrusted input formats, libvips is now paying the cost of that surface in memory-safety fixes, several credited to external fuzzing and security researchers. Format reach and attack surface are growing together.
◆ Prediction
With 8.18.3-rc1 dominated by loader bounds checks, the next tags are likely to continue as patch-level hardening on the 8.18 line rather than open a new format frontier.
