Release v0.3.5

Fixed broken release process

Release v0.3.4

Breaking Changes

• None

---

New Features

• Add streaming_timeout_ms to OpenCodeGoConfig and OpenCodeZenConfig for per‑request streaming timeouts.
• Expose heartbeat_paused flag during raw Anthropic streaming to avoid keep‑alive injection into SSE frames.
• Add IsAnthropicModel and isAnthropicNativeGo helpers that now include minimax‑m2.5/2.7/3 and qwen‑plus models.
• Add RequestTimeout, StreamingTimeout, and StreamIdleTimeout helpers on OpenCodeClient.
• Add walkthrough.md documenting integration and timeout configuration.

Bug Fixes

• Fix streaming timeout handling: bind streaming body reads to the per‑attempt context so mid‑stream stalls abort.
• Prevent panic when transformTools receives a whitespace‑only "null" schema.
• Stop fallback chain early on parent context cancellation or deadline exceeded; do not record client cancellations as circuit‑breaker failures.
• Correct error handling in Anthropic API calls, surface ErrStreamReadCanceled, and streamline SSE error messages.
• Resolve lint issues in test files (discard unused return values, remove redundant type assertions).
• Fix concurrent write handling in TestResponseWriter by using Fprintf.

Improvements

• Harden transformTools: skip empty/whitespace names, normalize null/empty schemas, validate object type and properties, guard against nil schema objects.
• Update ApplyDefaults to honor streaming_timeout_ms before timeout_ms when the former is unset.
• Optimize retry logic and error handling with a dedicated APIError type.
• Reload messaging in atomic.go now reports timeout changes immediately.
• Add per‑byte idle‑gap enforcement via StreamIdleTimeout.

Documentation

• Update CONFIGURATION.md and README.md with Streaming Scenario Routing and new streaming_timeout_ms config.
• Add streaming_timeout_ms to config.example.json.
• Expand documentation for new timeout helpers and Anthropic‑native streaming behavior.

Chores

• Add extensive test coverage for new streaming and timeout features.
• Update test files and remove lint warnings.
• Minor refactorings in provider architecture and fallback logic.
• Update CI configuration and dependency checks.

Release v0.3.1

User Safety: safe

Release v0.3.0

Changelog

Breaking Changes

• Breaking Change: The model_overrides configuration now requires explicit model names for DeepSeek V4 Pro and Flash Free variants. Previous shorthand syntaxes are no longer supported.
• Breaking Change: Anthropic model routing now prioritizes Zen-specific endpoints over legacy Anthropic routing when IsZen is true. Existing Anthropic configurations may require updates to use model_overrides for compatibility.

New Features

• Add full Zen model support including Claude, GPT, Gemini, and free-tier models
• Add Claude model overrides for sonnet-4.6, opus-4.7, and haiku-4.5
• Add DeepSeek V4 Pro Zen override to config example and default config
• Add 49 Zen models grouped by endpoint type in models command output
• Add MiniMax M3 and Qwen3.7 profiles to model configuration
• Add grok-build-0.1, big-pickle, and north-mini-code-free models to config listing
• Add test coverage for Claude, Grok, Big-Pickle, North Mini-Code-Free, and missing Go models

Bug Fixes

• Fix endpoint classification to use Zen-specific routing (minimax uses chat completions on Zen)
• Fix streaming/non-streaming path checks to prioritize Zen over Anthropic routing
• Fix deprecated model names in documentation

Improvements

• Improve model documentation with updated endpoint tables and configuration examples
• Enhance configuration examples with DeepSeek V4 Pro/Flash Free override patterns
