--- title: "v1.4.10" description: "v1.4.10 changelog - 2026-03-03" --- ```bash npx -y @maximhq/bifrost --transport-version v1.4.10 ``` ```bash docker pull maximhq/bifrost:v1.4.10 docker run -p 8080:8080 maximhq/bifrost:v1.4.10 ``` ## ✨ Features - **Response Header Forwarding** — Forward provider response headers back to clients for all providers - **Streaming Compression** — Added streaming compression support for provider responses - **Bedrock Invoke & Count Tokens** — Added bedrock invoke support and count tokens for bedrock provider - **Async Rerank** — Added async support for rerank requests - **Dashboard Graphs** — Added new dashboard graphs and graph fixes - **Gzip for Azure Speech** — Added gzip compression for azure speech streams - **Grayswan Guardrails** — Added grayswan guardrails configuration - **E2E Tests** — Added e2e tests for API - **Azure Managed Identity** — option to provider key form (DefaultAzureCredential when no API key or Entra ID) - **Bedrock STS AssumeRole** — support (role_arn, external_id, session_name) in key config for cross-account access ## 🐞 Fixed - **Parallel Tool Call Deltas** — Route parallel tool call argument deltas by id/index to prevent argument merging during streaming (thanks [@KTS-o7](https://github.com/KTS-o7)!) - **Count Tokens Route** — Count tokens route fixed to match OpenAI schema **Breaking change.** The count tokens route has moved from `/v1/count_tokens` to `/v1/responses/input_tokens`, and the request body field has been renamed from incorrect `messages` to `input`. Please update your clients accordingly. - **Cached Tokens Handling** — Standardized cached tokens handling for all providers **Breaking change.** Cache tokens moved from usage top-level into `prompt_tokens_details` (Chat) and `input_tokens_details` (Responses), with standardized keys. If you have persisted data (logs, analytics, or custom storage), migrate: (1) move `usage.cache_read_input_tokens` → `usage.prompt_tokens_details.cached_read_tokens` or `usage.input_tokens_details.cached_read_tokens`; (2) move `usage.cache_creation_input_tokens` → `usage.prompt_tokens_details.cached_write_tokens` or `usage.input_tokens_details.cached_write_tokens`. - **Team update** fixes team update flow by handling nil customer id - **Bedrock Integration Routing** — Added missing routing logic for bedrock integration - **Nil Tool Properties** — Handle nil properties in tool function parameters - **Logprobs JSON Tag** — Fixed logprobs JSON tag in BifrostResponseChoice (thanks [@robechun](https://github.com/robechun)!) - **Provider Deletion** — Fixed delete providers bug, empty provider list bug, and deleting provider not loaded in memory - **Data Connectors** — Fixed enabling/disabling data connectors - **OpenRouter Keys** — Added proper status check for openrouter keys - **Governance Virtual Key** — Added governance wrong virtual key check - **Pricing Config** — Normalized framework pricing config - **Model Limit Validation** — Fixed model limit form validation - **Dashboard Height** — Minor dashboard height fix - feat: added response header forwarding for providers - feat: added streaming compression support for providers - feat: added bedrock invoke and count tokens support - feat: added gzip compression for azure speech streams - feat: add Azure DefaultAzureCredential support — use managed identity when no API key or Entra ID credentials provided - feat: add Bedrock STS AssumeRole support (role_arn, external_id, session_name) in key config for cross-account access - fix: standardized cached tokens handling across all providers **Breaking change.** Cache tokens moved from usage top-level into `ChatPromptTokensDetails` (`prompt_tokens_details`) and `ResponsesResponseInputTokens` (`input_tokens_details`), with standardized keys. If you have persisted data (logs, analytics, or custom storage), migrate: (1) move `usage.cache_read_input_tokens` → `usage.prompt_tokens_details.cached_read_tokens` or `usage.input_tokens_details.cached_read_tokens`; (2) move `usage.cache_creation_input_tokens` → `usage.prompt_tokens_details.cached_write_tokens` or `usage.input_tokens_details.cached_write_tokens`. - fix: handle nil properties in tool function parameters - fix: fixed logprobs JSON tag in BifrostResponseChoice (thanks [@robechun](https://github.com/robechun)!) - fix: added proper status check for openrouter keys - feat: added response header forwarding support - feat: added new dashboard graphs and graph fixes - feat: added bedrock invoke streaming support - fix: standardized cached tokens handling - fix: preserve parallel tool call deltas during streaming (thanks [@KTS-o7](https://github.com/KTS-o7)!) - fix: added proper status check for openrouter keys - chore: bump core to 1.4.6 - feat: added governance wrong virtual key check - feat: added streaming compression support - fix: added bedrock integration support for routing in governance - chore: bump core to 1.4.6 and framework to 1.2.25 - chore: bump core to 1.4.6 and framework to 1.2.25 - chore: bump core to 1.4.6 and framework to 1.2.25 - feat: added response header forwarding support - feat: added new dashboard graphs - fix: count tokens route fixes - chore: bump core to 1.4.6 and framework to 1.2.25 - chore: bump core to 1.4.6 and framework to 1.2.25 - chore: bump core to 1.4.6 and framework to 1.2.25 - chore: bump core to 1.4.6 and framework to 1.2.25 - fix: DefaultCacheKey dropped during JSON unmarshal (thanks [@Georgehe4](https://github.com/Georgehe4)!) - chore: bump core to 1.4.6 and framework to 1.2.25 - chore: bump core to 1.4.6 and framework to 1.2.25
