 - **providers:** add Qwen Web (chat.qwen.ai) web-cookie provider (#2947 — thanks @oyi77)
 - **Quota Share Engine — multi-provider quota pools** — Monitoring/Costs reorg plus a Quota Share Engine: group selector, grouped pool cards, exclusive-quota API keys (`allowedQuotas`), `quotaShared-*` routing models via combos, a 3-step pool wizard (legacy Plans page retired), endpoint + key preview, and full pool editing. Adds quota-pool DB migrations. (#2859 / #3022 / #3032 — thanks @diegosouzapw)
 - **Dashboard page redesigns (Nav Restructure)** — agent-skills + omni-skills with a dynamic 42-skill catalog and MCP/A2A discovery (#2827); CLI Code's + CLI Agents + ACP Agents pages (#2839); translator friendly redesign, 5 tabs → 2 (#2847); functional `/batch` + `/batch/files` redesign (#2849); Playground Studio + Search Tools Studio (#2869); memory engine redesign — sqlite-vec + hybrid RRF + Studio UI (#2873). (thanks @diegosouzapw)
-- **notion:** add Notion as an MCP context source — 6 tools (`notion_search`, `notion_list_databases`, `notion_get_database`, `notion_query_database`, `notion_read`, `notion_append_blocks`) scoped under `read:notion` / `write:notion`, with dashboard "Context Sources" tab, settings API, and token persistence in `key_value` table (#2959)

+- **Per-API-key stream default mode** — a per-key setting that forces JSON or SSE as the default response shape (migration `077_api_key_stream_default_mode`), so integrations that expect non-streaming JSON work without client changes. (thanks @JxnLexn)

 - **dashboard:** use a lightweight ping endpoint for the MaintenanceBanner (fixes #3040) (#3043 — thanks @herjarsa)
 - **test:** resolve pre-existing test failures — env sync, PII, quota, sidebar (#3039 — thanks @oyi77)
 - **docs/mcp:** regenerate the mcp-tools diagram for 43 tools and fix the tool count (#3028 — thanks @diegosouzapw)
-- **mcp:** move `enforceScopes` guard before `MCP_TOOL_MAP` lookup, add inline `scopes` parameter to `withScopeEnforcement()`, and declare scopes on all 24 dynamic tool definitions (memory, skills, plugins, gamification, compression) to fix scope enforcement for dynamic MCP tool groups (#2958)

+- **sse/chatCore:** the heap-pressure guard now auto-calibrates its threshold to 85%
+  of the live V8 heap ceiling (floor 400 MB) instead of a fixed 200 MB that sat below
+  the app's ~260 MB baseline and returned `503 Service temporarily unavailable due to
+  resource pressure` for every request once the heap warmed up. It now tracks
+  `--max-old-space-size` across 1 GB / 2 GB / large VPS; `HEAP_PRESSURE_THRESHOLD_MB`
+  still overrides. (#3052)
+- **proxy:** fail closed for OAuth usage-account proxies (#3051 — thanks @terence71-glitch)
+- **proxy:** resolve registry proxy assignments for combo and key levels (#3048 — thanks @terence71-glitch)
+- **providers/web:** wire the session pool for fingerprint rotation on Pollinations / DuckDuckGo (#3049 — thanks @oyi77)
+- **providers/claude-web:** add `cf_clearance` cookie support and session-pool fingerprint rotation for Pollinations / DuckDuckGo (#3046 — thanks @oyi77)
