What's New
Newer agentgateway adds API-key budgets and Gemini support with breaking changes to token counting and policy merging.
Breaking Changes
- LLM token counts now include prompt-cache tokens, changing normalized input metrics.
- JWT issuer and audience claims are now required when configured.
- Backend and attached LLM policies now merge field by field instead of replacing.
- Cross-namespace route delegation now requires a ReferenceGrant.
- Managed API key metadata uses the `agentgateway.dev/` prefix.
New Features
- API-key-scoped budgets and model access for standalone deployments.
- Native Gemini APIs and broader format conversion between Anthropic and OpenAI.
- Enhanced guardrails for tool calls and OpenAI inline moderation.
- Deeper Agent Substrate integration and SPIFFE Workload API identities.
- Richer dynamic forward proxy and TCP support.
Improvements
- Better LLM log views with in-depth request and response details.
- UI, traces, logs, metrics, and `agctl` provide clearer views of multi-turn agent activity.
- Deeper Agent Substrate integration.
Upgrade Notes
Update JWT issuer and audience claims, migrate API key metadata to the `agentgateway.dev/` prefix, and add ReferenceGrants for cross-namespace delegation. LLM token metrics will change to include cache tokens, and policy merging behavior has shifted.
