 # Changelog
 
+## 2025-10-31 - 2.1.0 - feat(stocks)
+Add unified stock data API (getData) with historical/OHLCV support, smart caching and provider enhancements
+
+- Introduce discriminated union request types (IStockDataRequest) and a unified getData() method (replaces legacy getPrice/getPrices for new use cases)
+- Add OHLCV fields (open, high, low, volume, adjusted) and metadata (dataType, fetchedAt) to IStockPrice
+- Implement data-type aware smart caching with TTLs (historical = never expire, EOD = 24h, live = 30s, intraday matches interval)
+- Extend StockPriceService: new getData(), data-specific cache keys, cache maxEntries increased (default 10000), and TTL-aware add/get cache logic
+- Enhance Marketstack provider: unified fetchData(), historical date-range retrieval with pagination, exchange filtering, batch current fetch, OHLCV mapping, and intraday placeholder
+- Update Yahoo provider to include dataType and fetchedAt (live data) and maintain legacy fetchPrice/fetchPrices compatibility
+- Add/adjust tests to cover unified API, historical retrieval, OHLCV presence and smart caching behavior; test setup updated to require explicit OpenData directory paths
+- Update README to document v2.1 changes, migration examples, and new stock provider capabilities
+
+## 2025-10-31 - 2.0.0 - BREAKING CHANGE(OpenData)
+Require explicit directory paths for OpenData (nogit/download/germanBusinessData); remove automatic .nogit creation; update HandelsRegister, JsonlDataProcessor, tests and README.
+
+- Breaking: OpenData constructor now requires a config object with nogitDir, downloadDir and germanBusinessDataDir. The constructor will throw if these paths are not provided.
+- Removed automatic creation/export of .nogit/download/germanBusinessData from ts/paths. OpenData.start now ensures the required directories exist.
+- HandelsRegister API changed: constructor now accepts downloadDir and manages its own unique download folder; screenshot and download paths now use the configured downloadDir.
+- JsonlDataProcessor now accepts a germanBusinessDataDir parameter and uses it when ensuring/storing data instead of relying on global paths.
+- Updated tests to provide explicit path configuration (tests now set testNogitDir, testDownloadDir, testGermanBusinessDataDir and write outputs accordingly) and to use updated constructors and qenv usage.
+- Documentation updated (README) to document the breaking change and show examples for required directory configuration when instantiating OpenData.
+- Added .claude/settings.local.json for local permissions/config used in development/CI environments.
+
+## 2025-10-11 - 1.7.0 - feat(stocks)
+Add Marketstack provider (EOD) with tests, exports and documentation updates
+
+- Add MarketstackProvider implementation (ts/stocks/providers/provider.marketstack.ts) providing EOD single and batch fetching, availability checks and mapping to IStockPrice.
+- Export MarketstackProvider from ts/stocks/index.ts so it is available via the public API.
+- Add comprehensive Marketstack tests (test/test.marketstack.node.ts) covering registration, health checks, single/batch fetches, caching, ticker/market validation, provider stats and sample output.
+- Update README with Marketstack usage examples, configuration, API key instructions and provider/health documentation.
+- Bump dev dependency @git.zone/tstest to ^2.4.2 in package.json.
+- Add project helper/config files (.claude/settings.local.json, .serena/project.yml and .serena/.gitignore) to support CI/tooling.
+
+## 2025-09-24 - 1.6.1 - fix(stocks)
+Fix Yahoo provider request handling and bump dependency versions
+
+- Refactored Yahoo Finance provider to use SmartRequest.create() builder and await response.json() for HTTP responses (replaces direct getJson usage).
+- Improved batch and single-price fetching to use the SmartRequest API, keeping User-Agent header and timeouts.
+- Added a compile-time type-check alias to ensure IStockPrice matches tsclass.finance.IStockPrice.
+- Bumped development and runtime dependency versions (notable bumps include @git.zone/tsbuild, @git.zone/tstest, @push.rocks/qenv, @push.rocks/smartarchive, @push.rocks/smartdata, @push.rocks/smartfile, @push.rocks/smartlog, @push.rocks/smartpath, @push.rocks/smartrequest, @tsclass/tsclass).
+- Added .claude/settings.local.json to grant local CI permissions for a few Bash commands.
+
+## 2025-07-12 - 1.6.0 - feat(readme)
+Revamp documentation and package description for enhanced clarity
+
+- Restructured README to highlight real-time stock data and German business data, streamlining quick start and advanced examples
+- Updated package.json description to better reflect library capabilities
+- Added .claude/settings.local.json to define permissions for external tools
+- Refined code examples in tests and documentation for improved clarity and consistency
+
 ## 2025-04-09 - 1.5.3 - fix(test)
 Await file writes in Handelsregister tests to ensure all downloads complete before test end
