release: v0.7.0 release notes (#2177)
**Description** New Features Multi-Tenant Hostname Routing - AIGatewayRoute gains a hostnames field enabling hostname-based model scoping — serve different model catalogs per tenant from a single Gateway - /v1/models automatically scopes its response to models matching the request's Host header - Wildcard hostnames (*.ai.example.com) supported via Gateway API hostname matching rules Provider Translation - Anthropic → AWS Bedrock Converse — new translator path lets Anthropic-native clients reach Bedrock without switching protocols (text, images, tool use, thinking, streaming) - Anthropic → OpenAI reasoning & image support — thinking/reasoning blocks and image content no longer silently dropped during translation - Claude Opus 4.7 reasoning — display parameter (summarized/omitted), xhigh effort tier, and claude-mythos-preview model recognition - Anthropic prefix support — VersionedAPISchema.prefix now works for Anthropic backends (e.g., /{prefix}/messages) - anthropic-beta header forwarding — mapped into anthropic_beta body field for AWSAnthropic backends OpenAI API Compatibility - Audio transcription & translation — full data-plane support for /v1/audio/transcriptions and /v1/audio/translations (Whisper endpoints, multipart/form-data) - Azure OpenAI Responses API — /v1/responses routes to Azure's /openai/responses?api-version=... path - audio_url and video_url content types — multimodal audio/video inputs for compatible backends (vLLM, phi-4-mm, Qwen 3.5) Quota-Aware Routing - Backend rate limit filter injection for QuotaPolicy — first runtime enforcement: controller injects a backend rate limit filter when a QuotaPolicy is attached to an AIServiceBackend MCP Gateway - Authorization-filtered tools/list — omits tools the caller isn't authorized to invoke, preventing tool discovery leaks Observability - Smarter log redaction — developer-authored metadata (tool descriptions, function names, JSON schemas) visible in debug logs; user content and AI-generated text remain redacted API Changes - AIGatewayRoute.spec.hostnames — new optional field for hostname-based request filtering - AIGatewayRoute.spec.rules capped at 15 (down from 128) to match Gateway API HTTPRoute limits - VersionedAPISchema.prefix extended to Anthropic backends - QuotaPolicy now has runtime enforcement (backend rate limit filter injection) Bug Fixes - SSE parser handles data:{json} (no space after colon) - Responses API streaming: buffer incomplete SSE events across response body chunks - Responses API: capture token usage from response.incomplete and response.failed events - Nil-pointer guard in AWS Bedrock response translator (HTTP 200 with no output field) - Comprehensive Gemini finish-reason mapping (previously everything fell through to content_filter) - GCP Vertex AI streaming: emit empty delta object instead of omitting it - Responses API: handle typeless assistant output messages (e.g., from OpenCode) Docs - Proposal: MCPBackend CRD (#2144) - Proposal: OAuth 2.0 Token Exchange as Upstream Auth for MCP Backends (#2052) CI - contents:write permission declared on Release workflow's release job (#2139) --------- Signed-off-by: achoo30 <achoo30@bloomberg.net> Signed-off-by: Erica Hughberg <erica.sundberg.90@gmail.com> Co-authored-by: Erica Hughberg <erica.sundberg.90@gmail.com> Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
