 # Changelog
 
+## 2025-11-07 - 3.5.0 - feat(stocks)
+Add provider fetch limits, intraday incremental fetch, cache deduplication, and provider safety/warning improvements
+
+- Add maxRecords and defaultIntradayLimit to IProviderConfig to control maximum records per request and default intraday limits.
+- CoinGecko provider: enforce maxRecords when processing historical data, warn when large historical/intraday results are returned without explicit limits, preserve priority mappings when rebuilding the coin cache, and improve cache load logging.
+- Marketstack provider: make safety maxRecords configurable, apply a configurable default intraday limit, warn when no explicit limit is provided, and ensure effective limits are applied to returned results.
+- StockPriceService: always attempt incremental fetch for intraday requests without a date to fetch only new data since the last cached timestamp and fall back to full fetch when necessary.
+- StockPriceService: deduplicate price arrays by timestamp before caching and after merges to avoid duplicate timestamps and reduce cache bloat.
+- Introduce StockDataService for unified access to prices and fundamentals with automatic enrichment (market cap, P/E, price-to-book) and caching improvements.
+- Various cache/TTL improvements and safer default behaviors for intraday, historical and live data to improve performance and memory usage.
