What's New
The older release is a massive overhaul of an agent routing system (OmniRoute), while the newer release focuses on SDK stability and CLI improvements for a different product.
Breaking Changes
- Billing class logic now requires a curated per-connection catalog; uncurated connections are treated as metered rather than plan-included.
- Traversal is refused in the Codex `/v1/responses` subpath for security.
- Pre-request hooks now run in an isolated realm (GHSA-9p9m).
- Go SDK: Removed `workspace.Credentials.AccessTokens` and read stored logins only from the `accounts` object of `credentials.json`.
New Features
- Proxy native ElevenLabs voices, text-to-speech, and speech-to-text HTTP routes.
- Google AI Studio Gemini batch text-to-speech support via POST /v1/audio/speech.
- Subscription-first auto groupings with plan-included connections and hard-stop overage logic.
- Management-authenticated versioned web-session credential contract.
- Pulumi neo tool reports console URLs and update identifiers.
Improvements
- Enhanced routing with hierarchical concurrency admission and adaptive reasoning effort.
- Security hardening including pre-request hooks in an isolated realm and traversal refusal in Codex.
- Proxy improvements including egress-IP visibility and selector steering away from refused members.
- Video/Audio bridge enhancements including hardened drill-down cache and bounded transcript contracts.
- Improved consistency in union type printing within PCL.
Bug Fixes
- Fixed provider fallback logic for extension packages in Go and Python SDKs.
- Fixed duplicate provider documentation links in credentials warnings.
- Hardened drill-down cache substrate for Video Bridge with exact-path broker policy.
- Order union type members by fixed structural order for consistent printing.
Upgrade Notes
The older release requires migrating billing logic to use curated catalogs. The newer release requires removing `workspace.Credentials.AccessTokens` from Go SDK code and updating .NET and Java SDK versions.
