Ships a frontier model roughly monthly, then adds the admin controls weeks later.
Two model launches in under four weeks — Sonnet 5 on June 30, Opus 5 on July 24 — with Opus 5 positioned near Fable 5's intelligence at half the price. Around the models the surface area keeps widening: Claude Tag in Slack, Cowork moving to web and mobile with sessions running remotely, and a Microsoft 365 connector that now writes instead of only reading. A parallel track adds admin machinery — Trusted Devices, model entitlements, self-serve HIPAA, and now scanning for third-party skills and plugins.
Semantic Kernel is in orderly maintenance while Microsoft Agent Framework takes over.
Semantic Kernel ships parallel .NET and Python trains on version-only tags, and most of what lands is dependency bumps, security hardening and CodeQL noise suppression. The exceptions are narrow but real: Python 1.44.1 adds a breaking MCP tool approval callback for Azure AI Agent and skips MCP tools whose normalised names collide, while earlier point releases tightened OpenAPI parsing and function-choice behaviour for assistant agents. Release cadence is roughly monthly per language with little feature surface between tags.

The pattern across this window is reach first, govern second: each capability that puts Claude inside someone's workplace is followed within weeks by a control that lets an admin constrain it. Cowork's remote execution and the Microsoft 365 write tools move Claude from a chat surface to something that acts on mail, calendars, and files with nobody watching. The extension ecosystem is being handled the same way — skills and plugins shipped first, malicious-content scanning arrived after.
Expect the governance layer to catch up with the newest capability: controls scoped to Cowork's remote sessions and to connector write permissions, and skill/plugin scanning graduating out of Enterprise beta. The half-price framing of Opus 5 suggests price, not only capability, is now part of how launches are pitched.

Release cadence is roughly monthly per language with little feature surface between tags.
The repository itself states the direction — releases in this window carry a Microsoft Agent Framework successor callout in the READMEs and .NET migration samples updated for Agent Framework 1.0 compatibility. Semantic Kernel is being kept correct and secure rather than extended, with the remaining substantive work concentrated on MCP correctness and OpenAPI plugin safety. Teams should read new tags as stability maintenance on a library with a named successor, not as continued investment.
Expect the cadence to continue as security and dependency servicing with occasional MCP fixes, and for migration tooling or documentation pointing at Microsoft Agent Framework to grow faster than any new capability in Semantic Kernel itself.
