+## [3.0.7] — 2026-03-25
+
+### 🐛 Bug Fixes
+
+- **Antigravity Token Refresh:** Fixed `client_secret is missing` error for npm-installed users — the `clientSecretDefault` was empty in providerRegistry, causing Google to reject token refresh requests (#588)
+- **OpenCode Zen Models:** Added `modelsUrl` to the OpenCode Zen registry entry so "Import from /models" works correctly (#612)
+- **Streaming Artifacts:** Fixed excessive newlines left in responses after thinking-tag signature stripping (#626)
+- **Proxy Fallback:** Added automatic retry without proxy when SOCKS5 relay fails
+- **Proxy Test:** Test endpoint now resolves real credentials from DB via proxyId
+
+### ✨ New Features
+
+- **Playground Account/Key Selector:** Persistent, always-visible dropdown to select specific provider accounts/keys for testing — fetches all connections at startup and filters by selected provider
+- **CLI Tools Dynamic Models:** Model selection now dynamically fetches from `/v1/models` API — providers like Kiro now show their full model catalog
+- **Antigravity Model List:** Updated with Claude Sonnet 4.5, Claude Sonnet 4, GPT 5, GPT 5 Mini; enabled `passthroughModels` for dynamic model access (#628)
+
+### 🔧 Maintenance
+
+- Merged PR #625 — Provider Limits light mode background fix
+
+---
+
+## [3.0.6] — 2026-03-25
+
+### 🐛 Bug Fixes
+
+- **Limits/Proxy:** Fixed Codex limit fetching for accounts behind SOCKS5 proxies — token refresh now runs inside proxy context
+- **CI:** Fixed integration test `v1/models` assertion failure in CI environments without provider connections
+- **Settings:** Proxy test button now shows success/failure results immediately (previously hidden behind health data)
+
+### ✨ New Features
+
+- **Playground:** Added Account selector dropdown — test specific connections individually when a provider has multiple accounts
+
+### 🔧 Maintenance
+
+- Merged PR #623 — LongCat API base URL path correction
+
+---
+
+## [3.0.5] — 2026-03-25
+
+### ✨ New Features
+
+- **Limits UI:** Added tag grouping feature to the connections dashboard to improve visual organization for accounts with custom tags.
+
+---
+
+## [3.0.4] — 2026-03-25
+
+### 🐛 Bug Fixes
+
+- **Streaming:** Fixed `TextDecoder` state corruption inside combo `sanitize` TransformStream which caused SSE garbled output matching multibyte characters (PR #614)
+- **Providers UI:** Safely render HTML tags inside provider connection error tooltips using `dangerouslySetInnerHTML`
+- **Proxy Settings:** Added missing `username` and `password` payload body properties allowing authenticated proxies to be successfully verified from the Dashboard.
+- **Provider API:** Bound soft exception returns to `getCodexUsage` preventing API HTTP 500 failures when token fetch fails
