- **feat(storage):** Add database backup cleanup controls, UI management, and customizable retention period env vars (#1304)
- **feat(providers):** Add Freepik Pikaso image generation provider with support for cookie/subscription-based auth modes (#1277)
- **feat(providers): Add Perplexity Web (Session) Provider** — Routes through Perplexity's internal SSE API using a session cookie, giving native proxy access without separate API costs to GPT-5.4, Claude Opus, Gemini 3.1 Pro, and Nemotron via preferences mapping (#1289)
- **feat(api): Sync Tokens & V1 WebSocket Bridge** — Dedicated sync token storage, issuance, revocation, and bundle download routes backed by stable config bundle versioning with ETag support. Exposes `/v1/ws` WebSocket upgrade route and a custom Next.js server bridge (`scripts/v1-ws-bridge.mjs`) so OpenAI-compatible WebSocket traffic can be proxied through the gateway. Compliance auditing expanded with structured metadata, pagination, request context, auth/provider credential events, and SSRF-blocked validation logging. New migrations: `024_create_sync_tokens.sql`. New modules: `syncTokens.ts`, `src/lib/sync/bundle.ts`, `src/lib/sync/tokens.ts`, `src/lib/ws/handshake.ts`, `src/lib/apiBridgeServer.ts`, `src/lib/compliance/providerAudit.ts`.
- **feat(models): GLM Thinking Preset & Hybrid Token Counting** — GLM Thinking (`glmt`) registered as a first-class provider preset with shared GLM model metadata, pricing, per-connection usage sync, dashboard support, and `maxTokens: 65536 / thinkingBudgetTokens: 24576` request defaults with 900s extended timeout. Provider-side `/messages/count_tokens` endpoint used when a Claude-compatible upstream supports it; gracefully falls back to estimation on missing models, missing credentials, or upstream failures. Startup seeding of default model aliases (`src/lib/modelAliasSeed.ts`) normalizes common cross-proxy model dialects so canonical slash-based model IDs are not misrouted. New file `open-sse/config/glmProvider.ts`.
- **feat(core): Hardened Outbound Provider Calls & Cooldown Retries** — Guarded outbound fetch helpers (`src/shared/network/safeOutboundFetch.ts`, `src/shared/network/outboundUrlGuard.ts`) blocking private/local URLs with configurable retry, timeout normalisation, and route-level status propagation for provider validation and model discovery. Cooldown-aware chat retries (`src/sse/services/cooldownAwareRetry.ts`) with configurable `requestRetry` and `maxRetryIntervalSec` settings and model-scoped cooldown responses. Improved rate-limit learning from headers and error bodies so short upstream lockouts can recover automatically. Runtime environment validation (`src/lib/env/runtimeEnv.ts`) checks env at startup. Pollinations now requires an API key. Antigravity and Codex header handling aligned via `open-sse/config/antigravityUpstream.ts` and `open-sse/config/codexClient.ts`. Gemini tool names restored in translated responses; synthetic Claude text block injected when upstream SSE completes empty.
- **feat(logs):** Add TPS (Tokens Per Second) metric to log details modal metadata grid (#1182)
- **feat(memory+skills):** Full-featured Memory & Skills systems with FTS5 SQLite search, dynamic UI pagination, backend observability, and extensive test coverage (#1228)
- **feat(bailian-quota):** Add Alibaba Coding Plan quota monitoring, multi-window quota extraction, and UI credential validation (#1235)
- **feat(storage): Call Log Storage Refactor** — Extracted heavy request/response JSON payloads from the core SQLite database (`storage.sqlite`) into filesystem artifacts stored within `DATA_DIR/call_logs`. This massively reduces WAL bloat and eliminates `SQLITE_FULL` crashes on high-traffic nodes (#1307).
- **feat(providers): Add Grok Web (Subscription) Provider** — Routes through the xAI web interface for subscription users via cookie session mapping (#1295).
- **feat(api): Advanced Media Support** — Extends OpenAI generic proxy layer to natively support `image`, `embeddings`, `audio-transcriptions`, and `audio-speech` workflows (#1297).
- **feat(cli-tools): Qwen Code CLI Integration** — Full integration for Qwen Code local execution mapping, model resolution, and dynamic API key fetching (#1266, #1263).
- **feat(oauth):** Supports `cursor-agent` CLI as a native Cursor credential source alongside the standard configuration (#1258).
- **feat(models):** Custom and imported models now merge correctly into filter lists for all available global providers (#1191).

### 🐛 Bug Fixes

- **fix(mitm):** Compile MITM utilities as NodeNext ESM during prepublish, copy the CommonJS MITM server into the standalone artifact, and resolve MITM data paths without relying on Next.js aliases in packaged runtime.
- **fix(build):** Move the local `.tmp/wine32` Wine prefix out of the isolated Next.js build path so Windows Electron packaging artifacts cannot trigger `EACCES` scans during Node 24 builds.
- **fix(build):** Copy the `wreq-js` native runtime directory into the isolated Next.js standalone output so packaged Playwright/E2E starts can load the instrumentation hook on Linux.
- **fix(api):** Validate the Codex Responses websocket bridge and `/v1/batches` JSON payloads with Zod before use, keeping `request.json()` route validation green and returning explicit 400 responses for invalid bodies.
- **fix(providers):** Add explicit typing to provider alias and category helpers so the strict `typecheck:noimplicit:core` CI gate passes.
- **fix(ui):** Keep the upstream proxy provider detail page labeled with a fallback "Managed via Upstream Proxy Settings" management surface when translations are unavailable.
- **fix(electron):** Harden the production desktop CSP by removing `unsafe-eval` outside development and adding object, base URI, form action, frame ancestor, and worker restrictions.
- **fix(cli):** Replace shell-interpolated setup and privileged command execution paths with argument-based `spawn`/`execFile` helpers for database setup, Tailscale sudo commands, MITM DNS edits, and certificate install/uninstall flows.
- **fix(ui):** Keep provider icons resilient by using direct `@lobehub/icons` components first, then local PNG/SVG fallbacks, avoiding the `@lobehub/ui` peer runtime in the dashboard.

- **fix(providers):** match correct endpoint api.xiaomimimo.com for Xiaomi MiMo (#1303)
- **fix(core):** strip provider alias routing prefix from payload for custom endpoints to fix Azure OpenAI 400 errors (#1261)
- **fix(core):** ProxyFetch Undici dispatcher automatically bypasses LAN/local addresses, preventing fetch failures on internal OpenRouter requests (#1254)
- **fix(core):** Gemini thought stream signature detection upgraded to use native part.thought boolean, preventing reasoning text leaks (#1298)
- **deps:** bump hono from 4.12.12 to 4.12.14 to resolve CVE SSR HTML injection vulnerability (#1306, #59)
- **deps:** update dompurify to 3.4.0 in frontend overrides mitigating XSS HTML Injection (CVE-XYZ / Dependabot #60)
- **test:** Disable SQLite automatic backups during continuous integration (CI) tests to resolve E2E timeout issues limiting runner scaling (#24481475058)
- **feat(core): Proactive Context Compression** — `chatCore` now proactively compresses oversized message contexts before hitting upstream providers to dramatically reduce `context_length_exceeded` errors. Employs binary-search message pruning with structural integrity guarantees tracking explicit `tool_use` boundaries ensuring truncated tool inputs drop paired outputs appropriately (#1292, #1293)

- **fix(cli):** Resolve codex routing config parsing by strictly quoting section keys array, enforcing responses wire_api with fallback, and standardizing select-model button positioning mirroring Claude UI
- **fix(providers):** Correct Lobehub provider icons rendering by removing unsupported local references ensuring local SVG/PNG fallback mechanism invokes natively
- **fix(db):** Implement Database migration tracking safety abort safeguards (pre-migration backups via `VACUUM INTO` and mass renumbering warnings) to protect existing database structures on startup upgrades (#1281)
- **fix(dashboard):** Cleaned up target codex `config.toml` structure preventing recursive section rendering by enforcing quotes on section dot paths and mapping correct UI `OMNIROUTE_API_KEY` names.
- **fix(mcp):** Add dedicated explicit timeout constraint overrides for search handlers (#1280)
- **fix(crypto):** Add validation guard to encryption layer to surface clear UI errors when cryptographic environment variables are missing, replacing raw Node.js TypeErrors. Legacy env vars `OMNIROUTE_CRYPT_KEY` and `OMNIROUTE_API_KEY_BASE64` now also accepted as fallbacks (#1165)
- **fix(providers):** Update Pollinations provider definition to require API keys and specify their new limited pollen/hour free tier (#1177)
- **Streaming `\n\n` Artifact Fix (#1211):** Changed `<omniModel>` tag-stripping regex from `?` to `*` quantifier across `combo.ts`, `comboAgentMiddleware.ts`, and `contextHandoff.ts` to greedily strip all accumulated JSON-escaped newline sequences surrounding the tag. This prevents literal `\n\n` prefix artifacts from appearing in consumer streaming responses
- **E2E Combo Test Locator:** Fixed Playwright strict-mode violation in `combo-unification.spec.ts` by replacing ambiguous `getByRole` locator with a compound filter locator for the "All" strategy tab
- **fix(cc-compatible):** Trim beta flags and preserve cache passthrough for third-party HTTP proxy compatibility (#1230)
- **fix(providers):** Update Xiaomi MiMo endpoints to the live token-plan, migrating away from dead API URLs (#1238)
- **fix:** Forward client `x-initiator` header to GitHub Copilot upstream to accurately distinguish agent vs user turns (#1227)

- **fix(tests):** Resolve memory migration and skills route pagination bugs arising from PR overlaps
- **fix(i18n):** Add missing Chinese i18n support to dashboard components (`DataTable`, `EmptyState`, etc), update `en.json/zh-CN.json` routing keys, and natively resolve JSX defaults via `next-intl` (#1274)

### 🔧 Internal Improvements

- **Compliance Audit Expansion:** `src/lib/compliance/index.ts` expanded with structured metadata, pagination support, request context enrichment, and new `providerAudit.ts` module logging auth and provider credential events, SSRF-blocked validation attempts, and provider CRUD operations
- **Config Sync Bundle:** `src/lib/sync/bundle.ts` exports `buildConfigBundle()` generating a versioned JSON snapshot of settings, provider connections, nodes, model aliases, combos, and API keys (passwords redacted) with ETag support for bandwidth-efficient polling
- **Codex Client Constants:** Centralized `CODEX_CLIENT_VERSION`, `CODEX_USER_AGENT_PLATFORM`, and pattern-validated env overrides (`CODEX_CLIENT_VERSION`, `CODEX_USER_AGENT`) in `open-sse/config/codexClient.ts`
- **Antigravity Upstream Constants:** `open-sse/config/antigravityUpstream.ts` consolidates all Antigravity base URLs and model/fetchAvailableModels discovery path builders
- **Model Alias Seed:** `src/lib/modelAliasSeed.ts` seeds 30+ cross-proxy model dialect aliases (e.g. `openai/gpt-5` → `gpt-5`, `anthropic/claude-opus-4-6` → `cc/claude-opus-4-6`) at startup via idempotent `upsert`
- **Test Coverage:** 15+ new unit test suites covering sync routes, WebSocket bridge, compliance index, GLM provider config, cooldown-aware retry, safe outbound fetch, stream utilities, Codex executor, provider validation branches, model cross-proxy compatibility, and model alias seeding
- **TypeScript Migration:** Finalized migration of remaining JS tests (`proxy-load` and `testFromFile`) to TypeScript ES modules, ensuring a fully synchronized TS stack.
- **Reliability & Resilience:** Added exponential backoff to `models.dev` auto-sync to combat transient network failures, raised interval floor to 1 hour, and added LKGP debug logging for enhanced observability during routing. (#1286)
