What is Vault?

Vault under IBM lands 2.0.0, with FIPS 140-3 and HSM enterprise builds inside two weeks.

Vault crossed 2.0.0 in late March under its post-HashiCorp / IBM stewardship — the artifact pages now carry IBM's International Program License Agreement language alongside the existing MPL 2.0 / BSL terms. Enterprise variants followed within days: 2.0.0 enterprise FIPS 140-3 and HSM-flavored builds published April 1 and April 8, plus an sdk/v0.25.1 backport addressing a Go CVE. The recent shipping is release-engineering-heavy, not feature-heavy.

What is Ably?

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

Vault under IBM lands 2.0.0, with FIPS 140-3 and HSM enterprise builds inside two weeks.

◆ Current state

Vault crossed 2.0.0 in late March under its post-HashiCorp / IBM stewardship — the artifact pages now carry IBM's International Program License Agreement language alongside the existing MPL 2.0 / BSL terms. Enterprise variants followed within days: 2.0.0 enterprise FIPS 140-3 and HSM-flavored builds published April 1 and April 8, plus an sdk/v0.25.1 backport addressing a Go CVE. The recent shipping is release-engineering-heavy, not feature-heavy.

◆ Where it's heading

This is the cadence of a project completing a major-version rollout — community GA first, then RC and GA enterprise-flavor builds, then security-tracking SDK backports — rather than a roadmap pivot. The fact that FIPS 140-3 and HSM enterprise builds shipped in the same window as the 2.0 cycle is the signal worth holding onto: Vault's federal and regulated-industry posture is being kept intact under the new owner, and auth plugin version bumps suggest the wider ecosystem is staying in step.

◆ Prediction

Expect 2.x feature-bearing minor releases over the next few months, with FIPS 140-3 and HSM enterprise variants tracked alongside the community builds. GA bumps for the auth plugins to match the 2.x line are likely. Worth watching for more visible IBM branding or any Cloud-side packaging shifts that signal repositioning under the new owner.

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

◆ Current state

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

◆ Where it's heading

The clear direction is extending Ably's pub/sub and LiveObjects primitives into agentic, real-time AI sessions — session/run models, branching conversations, and human-in-the-loop handoff. The mature client SDKs are being kept stable and incrementally improved while the AI transport layer is where new capability is concentrating.

◆ Prediction

Expect the AI Transport SDK to march toward a 1.0 with tighter integration of Presence and LiveObjects into agent sessions, while the core client libraries continue their fix-and-refine cadence.
