What is Ably?
Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
What is Infisical?
PAM and PKI now take up most of the lines in Infisical's release notes.
Six releases in two weeks, each a flat PR list with no narrative. The recurring feature work is privileged access management — Redis account types and web access, filling account fields from a pasted connection string, machine identity access — and PKI, which gained AWS Private CA as an issuing authority and SCEP enrollment for Microsoft Intune. Secret management itself mostly appears as rotation coverage for Cloudflare API tokens and R2 access keys.

Ably
6.3INFRA · APIS
Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
◆ Current state
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
◆ Where it's heading
Ably is treating agent conversations as a transport problem — sessions, resumability, and multi-client reconciliation — rather than as a model-integration problem, and the primitives shipping in AI Transport keep pointing that way. The Pub/Sub line is being pulled along behind it: LiveObjects path APIs and React hooks are the state layer those agent sessions need. The pre-1.0 SDK will keep breaking as the shape settles, which is a reasonable trade while the category is unsettled.
◆ Prediction
Expect AI Transport to keep adding provider codecs beyond OpenAI Responses and to approach an API freeze as breaking changes get more expensive. LiveObjects support should continue spreading across the language SDKs, following the Java path-based API with other platforms.
Infisical
5.0INFRA · APIS
PAM and PKI now take up most of the lines in Infisical's release notes.
◆ Current state
Six releases in two weeks, each a flat PR list with no narrative. The recurring feature work is privileged access management — Redis account types and web access, filling account fields from a pasted connection string, machine identity access — and PKI, which gained AWS Private CA as an issuing authority and SCEP enrollment for Microsoft Intune. Secret management itself mostly appears as rotation coverage for Cloudflare API tokens and R2 access keys.
◆ Where it's heading
Infisical is assembling a credential platform rather than a secrets store, and it is doing so without a single headline release — each pillar arrives as two or three PRs per version. PKI is furthest along: issuing from an external AWS authority and enrolling devices through Intune puts it in territory previously held by dedicated certificate products. A third thread, the agent proxy, is accumulating the parts a product needs before launch — a Google Workspace service template, last-used timestamps, and adoption telemetry for proxied services.
◆ Prediction
The agent proxy is the thread most likely to get a real announcement; service templates and usage telemetry landing now are the groundwork a launch requires.
