+## [3.2.5] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Void Linux Deployment Support (#732)** — Integrated `xbps-src` packaging template and instructions to natively compile and install OmniRoute with `better-sqlite3` bindings via cross-compilation target.
+
+## [3.2.4] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Qoder AI Migration (#660)** — Completely migrated the legacy `iFlow` core provider onto `Qoder AI` maintaining stable API routing capabilities.
+
+### 🐛 Bug Fixes
+
+- **Gemini Tools HTTP 400 Payload Invalid Argument (#731)** — Prevented `thoughtSignature` array injections inside standard Gemini `functionCall` sequences blocking agentic routing flows.
+
+---
+
+## [3.2.3] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Provider Limits Quota UI (#728)** — Normalized quota limit logic and data labeling inside the Limits interface.
+
+### 🐛 Bug Fixes
+
+- **Core Routing Schemas & Leaks** — Expanded `comboStrategySchema` to natively support `fill-first` and `p2c` strategies to unblock complex combo editing natively.
+- **Thinking Tags Extraction (CLI)** — Restructured CLI token responses sanitizer RegEx capturing model reasoning structures inside streams avoiding broken `<thinking>` extractions breaking response text output format.
+- **Strict Format Enforcements** — Hardened pipeline sanitization execution making it universally apply to translation mode targets.
+
+---
+
+## [3.2.2] — 2026-03-29
+
+### ✨ New Features
+
+- **Four-Stage Request Log Pipeline (#705)** — Refactored log persistence to save comprehensive payloads at four distinct pipeline stages: Client Request, Translated Provider Request, Provider Response, and Translated Client Response. Introduced `streamPayloadCollector` for robust SSE stream truncation and payload serialization.
+
+### 🐛 Bug Fixes
+
+- **Mobile UI Fixes (#659)** — Prevented table components on the dashboard from breaking the layout on narrow viewports by adding proper horizontal scrolling and overflow containment to `DashboardLayout`.
+- **Claude Prompt Cache Fixes (#708)** — Ensured `cache_control` blocks in Claude-to-Claude fallback loops are faithfully preserved and passed safely back to Anthropic models.
+- **Gemini Tool Definitions (#725)** — Fixed schema translation errors when declaring simple `object` parameter types for Gemini function calling.
+
+## [3.2.1] — 2026-03-29
+
+### ✨ New Features
+
+- **Global Fallback Provider (#689)** — When all combo models are exhausted (502/503), OmniRoute now attempts a configurable global fallback model before returning the error. Set `globalFallbackModel` in settings to enable.
+
+### 🐛 Bug Fixes
+
+- **Fix #721** — Fixed context pinning bypass during tool-call responses. Non-streaming tagging used wrong JSON path (`json.messages` → `json.choices[0].message`). Streaming injection now triggers on `finish_reason` chunks for tool-call-only streams. `injectModelTag()` now appends synthetic pin messages for non-string content.
+- **Fix #709** — Confirmed already fixed (v3.1.9) — `system-info.mjs` creates directories recursively. Closed.
+- **Fix #707** — Confirmed already fixed (v3.1.9) — empty tool name sanitization in `chatCore.ts`. Closed.
+
+### 🧪 Tests
+
+- Added 6 unit tests for context pinning with tool-call responses (null content, array content, roundtrip, re-injection)
+

+### 🐛 Bug Fixes

+- **Claude Prompt Caching Passthrough** — Fixed cache_control markers being stripped in Claude passthrough mode (Claude → OmniRoute → Claude), which caused Claude Code users to deplete their Anthropic API quota 5-10x faster than direct connections. OmniRoute now preserves client's cache_control markers when sourceFormat and targetFormat are both Claude, ensuring prompt caching works correctly and dramatically reducing token consumption.

oyi77	c5003665c3	fix(translator): remove thoughtSignature from functionCall parts in all Gemini translators HTTP 400 "invalid argument" was triggered when OmniRoute translated tool calls to Gemini format, because thoughtSignature was injected onto every functionCall part unconditionally. Affects two code paths: 1. openai-to-gemini.ts — OpenAI tool_calls → Gemini functionCall 2. claude-to-gemini.ts — Claude tool_use blocks → Gemini functionCall thoughtSignature is only valid on thinking/reasoning parts (those with thought: true or thoughtSignature as their primary field). When present on a functionCall part, the Gemini API returns HTTP 400 'invalid argument'. The thinking parts that legitimately carry thoughtSignature (emitted when a message has reasoning_content / thinking blocks) are untouched. Regression tests (T43) cover: - single tool call: no thoughtSignature on functionCall part (openai path) - multiple tool calls: none carry thoughtSignature (openai path) - thinking regression guard: thoughtSignature still on thought parts - claude-to-gemini path: tool_use blocks produce clean functionCall parts Fixes #724	2026-03-29 08:48:58 +07:00

oyi77	48182edbd5	fix(translator): remove thoughtSignature from functionCall parts in Gemini translation HTTP 400 "invalid argument" was triggered when OmniRoute translated OpenAI tool_calls to Gemini format, because thoughtSignature was injected onto every functionCall part unconditionally. thoughtSignature is only valid on thinking/reasoning parts (those with thought: true). The Gemini API rejects any request where a functionCall part carries a thoughtSignature field, returning HTTP 400. Fix: remove the thoughtSignature field from functionCall parts. The thinking parts that legitimately require thoughtSignature (emitted when a message has reasoning_content) are unchanged. Adds regression test (T43) with three cases: - single tool call: no thoughtSignature on functionCall part - multiple tool calls: none carry thoughtSignature - thinking part regression guard: thoughtSignature still present on thought parts Fixes #725	2026-03-28 21:57:15 -03:00

diegosouzapw	cec833afc6	chore(release): v3.2.1 — context pinning fix + global fallback provider	2026-03-28 21:13:14 -03:00
diegosouzapw	f1cddba938	feat: add global fallback provider support (#689 ) When all combo models are exhausted (502/503), OmniRoute now checks for a globalFallbackModel setting and attempts one last request through it before returning the error. Settings stored in key_value table, no migration needed.	2026-03-28 21:10:29 -03:00
diegosouzapw	a0acdfdcb9	fix: context pinning bypass during tool-call responses (#721 ) Non-streaming: Fixed json.messages check to use json.choices[0].message (OpenAI format). Streaming: inject pin tag before finish_reason chunk for tool-call-only streams. injectModelTag now appends synthetic assistant message when content is null/array (tool_calls).	2026-03-28 21:04:47 -03:00
tombii	b84c915b23	fix(sse): preserve cache_control in Claude passthrough mode When Claude Code routes through OmniRoute (Claude → OmniRoute → Claude), OmniRoute was stripping all cache_control markers and replacing them with its own generic caching strategy. This broke Claude Code's carefully placed cache breakpoints for plans and other features. Changes: - Add preserveCacheControl parameter to prepareClaudeRequest() - Detect Claude passthrough mode (sourceFormat === targetFormat === CLAUDE) - Skip cache_control normalization when preserveCacheControl=true - Preserve client's cache_control markers in system, messages, and tools This ensures Claude Code's prompt caching optimization works correctly while maintaining OmniRoute's caching strategy for translation scenarios.
