Paginated release notes for World Monitor — new panels, data sources, API changes and fixes — built from the committed CHANGELOG.md so every release is crawlable.
2.5.1 2026-02-20
Performance / Fixed / Changed
Batch FRED API requests — frontend now sends a single request with comma-separated series IDs instead of 7 parallel edge function invocations, eliminating Vercel 25s timeouts
Parallel UCDP page fetches — replaced sequential loop with Promise.all for up to 12 pages, cutting fetch time from ~96s worst-case to ~8s
Bot protection middleware — blocks known social-media crawlers from hitting API routes, reducing unnecessary edge function invocations
Partial UCDP cache poisoning — failed page fetches no longer silently produce incomplete results cached for 6h; partial results get 10-min TTL in both Redis and memory, with partial: true flag propagated to CDN cache headers
FRED upstream error masking — single-series failures now return 502 instead of empty 200; batch mode surfaces per-series errors and returns 502 when all fail
Sentry Load failed filter — widened regex from ^TypeError: Load failed$ to ^TypeError: Load failed( \(.\))?$ to catch host-suffixed variants (e.g., gamma-api.polymarket.com)
Tooltip XSS hardening — replaced rawHtml() with safeHtml() allowlist sanitizer for panel info tooltips
2.5.0 2026-02-20
Highlights / Added / Changed / Fixed
Ollama / LM Studio integration — local AI summarization via OpenAI-compatible /v1/chat/completions endpoint with automatic model discovery, embedding model filtering, and fallback to manual text input
4-tier summarization fallback chain — Ollama (local) → Groq (cloud) → OpenRouter (cloud) → Transformers.js T5 (browser), each with 5-second timeout before silently advancing to the next
Shared summarization handler factory — all three API tiers use identical logic for headline deduplication (Jaccard >0.6), variant-aware prompting, language-aware output, and Redis caching (summary:v3:{mode}:{variant}:{lang}:{hash})
Settings window with 3 tabs — dedicated LLMs tab (Ollama endpoint/model, Groq, OpenRouter), API Keys tab (12+ data source credentials), and Debug & Logs tab (traffic log, verbose mode, log file access). Each tab runs an independent verification pipeline
Consolidated keychain vault — all desktop secrets stored as a single JSON blob in one OS keychain entry (secrets-vault), reducing macOS Keychain authorization prompts from 20+ to exactly 1 on app startup. One-time auto-migration from individual entries with cleanup
Cross-window secret synchronization — saving credentials in the Settings window immediately syncs to the main dashboard via localStorage broadcast, with no app restart needed
API key verification pipeline — each credential is validated against its provider's actual API endpoint. Network errors (timeouts, DNS failures) soft-pass to prevent transient failures from blocking key storage; only explicit 401/403 marks a key invalid
Plaintext URL inputs — endpoint URLs (Ollama API, relay URLs, model names) display as readable text instead of masked password dots in Settings
