 # Changelog
 
+## v3.10.6 (2026-05-25)
+
+**Freebuff Integration + Codebuff OAuth Fix + Windows Consolidation**
+
+### Freebuff (Free DeepSeek/Kimi)
+- **Freebuff integration**: Free DeepSeek/Kimi models via codebuff.com API
+- Fixed User-Agent to match official SDK: `ai-sdk/openai-compatible/1.0.25/codebuff`
+- Fixed metadata fields: `freebuff_instance_id` + `client_id` (base36 random) + `cost_mode: "free"`
+- Fixed session endpoint: POST empty `{}` body (not `{"model": model}`)
+- GUI preset aliases: "Freebuff (Free DeepSeek/Kimi)", "FreeBuff", "Codebuff (Free DeepSeek/Kimi)" all map to same backend
+
+### Codebuff Fix
+- Fixed Codebuff OAuth: use `www.codebuff.com` (bare `codebuff.com` returns 307 redirect)
+
+### OAuth Secrets & Credentials (All Providers)
+- **OAuth Secrets dialog now shows ALL providers**: Google (Antigravity + Gemini CLI) AND Freebuff/Codebuff
+- **Re-OAuth buttons** for each provider: instantly re-authenticate Google or GitHub/Codebuff
+- Token status indicators (valid/missing) for each Google provider
+- Shows logged-in email and auth status for Freebuff/Codebuff
+- Editable auth token and fingerprint fields for Freebuff/Codebuff
+
+### Windows
+- Windows GUI files consolidated into `src/` (merged by cobra91 via PR #1 and PR #2)
+
+### Proxy & GUI Improvements (cobra91 PR #3)
+- CROF adaptive logic gated to `crof.ai` only — no more log pollution for other providers
+- Data directory consolidation: all data now in `codex-proxy/` (was split across `codex-desktop/`, `codex-launcher/`, `codex-proxy/`)
+- Sticky proxy port: persists in `.last-proxy-port`, reused on restart so Codex Desktop keeps connection
+- Adaptive compact budget raised from 60% to 80% — avoids premature compaction on large-context models (DeepSeek v4 Pro 1M)
+- Config cleanup fix: stale `proxy-*.json` cleanup moved after `_init_runtime()` to avoid deleting active config
+- Windows GUI: added Clear Log, Restart Proxy, View Log buttons
+- **Linux/Windows feature parity**: both GUIs now have identical features
+- Windows GUI: ported OAuth Secrets all-providers dialog (Google + Freebuff/Codebuff with Re-OAuth buttons, token status)
+- Windows GUI: added Codebuff/Freebuff OAuth login flow (GitHub browser-based)
+- Windows GUI: added Sync from Preset button in endpoint editor
+- Linux GUI: added Clear Log + Restart Proxy buttons (matching Windows)
+
 ## v3.10.5 (2026-05-25)
