ElevenLabs is turning voice agents into versioned software, with weekly API surface to prove it.
The changelog is dominated by ElevenAgents, shipped as dense weekly API digests rather than feature posts. Agents now have branches, merges, rebases and version filters, plus procedures that compile into workflows, knowledge-base crawl jobs and per-agent sentiment analysis. Alongside that, the core model lines keep advancing: Music v2, Speech Engine, and now Dubbing v2 through the API.
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

Two arcs run in parallel. The agent platform is acquiring the mechanics of source control, which points at teams operating many agent versions in production rather than one hand-tuned assistant. The model lines are being rebuilt one at a time and exposed API-first, with older v1 models given explicit removal dates. Dubbing is the newest line to make that jump.
The v1 deprecation pattern suggests dubbing_v1 gets a removal date next, and the branch tooling looks close to gaining an approval or promotion step given merge previews already exist.

The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
