 # Changelog
 ## 2025-11-01 - 3.1.0 - feat(fundamentals)
 Add FundamentalsService and SEC EDGAR provider with caching, rate-limiting, tests, and docs updates
 - Introduce FundamentalsService to manage fundamentals providers, caching, retry logic and provider statistics
 - Add SecEdgarProvider to fetch SEC EDGAR company facts (CIK lookup, company facts parsing) with rate limiting and local caches
 - Expose fundamentals interfaces and services from ts/stocks (exports updated)
 - Add comprehensive tests for FundamentalsService and SecEdgarProvider (new test files)
 - Update README with new Fundamentals module documentation, usage examples, and configuration guidance
 - Implement caching and TTL handling for fundamentals data and provider-specific cache TTL support
 - Add .claude/settings.local.json (local permissions) and various test improvements
 ## 2025-10-31 - 3.0.0 - BREAKING CHANGE(stocks)
 Unify stock provider API to discriminated IStockDataRequest and add company name/fullname enrichment
 - Replace legacy provider methods (fetchPrice/fetchPrices) with a single fetchData(request: IStockDataRequest) on IStockProvider — providers must be migrated to the new signature.
 - Migrate StockPriceService to the unified getData(request: IStockDataRequest) API. Convenience helpers getPrice/getPrices now wrap getData.
 - Add companyName and companyFullName fields to IStockPrice and populate them in provider mappings (Marketstack mapping updated; Yahoo provider updated to support the unified API).
 - MarketstackProvider: added buildCompanyFullName helper and improved mapping to include company identification fields and full name formatting.
 - YahooFinanceProvider: updated to implement fetchData and to route current/batch requests through the new unified request types; historical/intraday throw explicit errors.
 - Updated tests to exercise the new unified API, company-name enrichment, caching behavior, and provider direct methods.
 - Note: This is a breaking change for external providers and integrations that implemented the old fetchPrice/fetchPrices API. Bump major version.
 ## 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
