What is Hex?

Hex is moving its agent out of the notebook and onto programmable surfaces.

Hex ships a fortnightly digest, and the through-line across the last ten is agent reach. The agent now runs from a CLI and API, appears inside Codex, acts as an MCP client against the user's own apps, can search the web, and can see the generative apps it builds. Alongside that, the model layer has become a customer-facing control: a picker, an admin-set default, Auto with visible attribution, and a rotating roster including Fable 5, Kimi K2.7, Claude Opus 5 and GPT-5.6.

What is silx?

silx settles into maintenance a release after its PySide6 migration

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

Hex is moving its agent out of the notebook and onto programmable surfaces.

◆ Current state

Hex ships a fortnightly digest, and the through-line across the last ten is agent reach. The agent now runs from a CLI and API, appears inside Codex, acts as an MCP client against the user's own apps, can search the web, and can see the generative apps it builds. Alongside that, the model layer has become a customer-facing control: a picker, an admin-set default, Auto with visible attribution, and a rotating roster including Fable 5, Kimi K2.7, Claude Opus 5 and GPT-5.6.

◆ Where it's heading

Hex is positioning the agent as a component other systems call rather than a feature users visit. Governance is being built out in parallel — spend limits, credit usage controls, enterprise role-request controls, signed embedding — which is the pattern of a product preparing for programmatic usage it does not directly supervise. The generative-app surface is drifting the same way, from generated output toward editable, brandable, embeddable artifacts.

◆ Prediction

Expect the CLI and API surface to deepen before the notebook UI gains much, with more of Context Studio and app management reachable programmatically, and expect the spend and role controls to keep pace as headless usage grows.

silx settles into maintenance a release after its PySide6 migration

◆ Current state

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

◆ Where it's heading

The cadence has slowed markedly since April, and the content has shifted from structural change to plotting and colormap refinement. That is the expected shape after a binding migration: downstream beamline code needs a stable target, so the project trades feature velocity for a quiet surface. The gap between 3.0.1 in May and 3.1.0 in August is the clearest signal of the deliberate slowdown.

◆ Prediction

Expect further point releases servicing the plotting and fitting widgets rather than another structural change, with feature work continuing to arrive in the 3.1.x minors rather than patches.
