yahoofinancer 0.6.1

Bug Fixes & Architectural Improvements

• Financial Statements Restoration: Added working $get_income_statement(), $get_balance_sheet(), and $get_cash_flow() methods on Ticker backed by Yahoo’s fundamentals-timeseries endpoint with support for frequency = c("annual", "quarterly"). Updated yf_get_financials() to return tidy tibbles with line items. (#48, #2)
• Unified HTTP Request Engine: Centralized all API communication into a unified internal api_request() helper with automatic retry, timeout, user agent header, and structured error reporting across all endpoints. (#49)
• Standardized Failure Contracts: Multi-symbol routines (Tickers$aggregate_data(), yf_download_prices(), yf_get_financials(), yf_get_market_stats(), yf_get_index_quotes()) consistently warn on failed symbols and return empty tibbles matching documented schemas on full failure. currency_converter(), Ticker$recommendations, and Ticker$valuation_measures unified to standard failure returns. (#50, #61)
• Batch Symbol Validation & Offline Construction: validate() vectorizes symbol queries into a single HTTP request. Added validate = TRUE option on Tickers$new(), Index$new(), and Index$set_index() to permit offline instantiation. (#51, #5, #61)
• Date Hygiene & Lookback Limit Enforcement: get_history() validates dates client-side and enforces intraday lookback boundaries (1m <= 7d, 5m/15m/30m <= 60d, 1h <= 730d). Fixed period = NULL lookback crash. currency_converter() guards against NA date inputs. (#52, #60)
• Robust Parsing & Transport Resilience: Handled transport-level network errors gracefully with informative warnings. Guarded against missing or mismatched adj_close series and invalid JSON payloads. (#60, #17)
• Hermetic & Live Smoke Testing: Expanded offline mock coverage with recorded httptest2 fixtures for fundamentals-timeseries statements, migrated mock fixtures to short paths, and added an offline-guarded live smoke test suite. (#53, #62)
• Package Hygiene & Code Style: Declared R (>= 4.1) floor, removed unused httptest Suggests, configured .lintr with zero remaining lints, added GitHub Actions lint workflow, updated User-Agent to yahoofinancer/<version>, and drafted the fundamental screening vignette. (#54, #57)

yahoofinancer 0.6.0

Enhancements

• Functional API: Introduced yf_download_prices(), yf_get_market_stats(), yf_get_financials(), and yf_get_index_quotes() for pipe-friendly, tidy data analysis workflows.
• Migration to httr2: Migrated package networking from httr to httr2 for modern, resilient HTTP operations.

yahoofinancer 0.5.0

Bug Fixes

• Error in currency converter adjusted closing (#21)
• Error in extracting historical values for stock (#22)

Enhancements

• Multiple Tickers: Get data for multiple tickers (#19, #20)
• Unified Object Model: Re-engineered duplicated code patterns by crafting a foundational YahooFinanceBase R6 parent class, modernizing object inheritance for Ticker and Index instances. (#25)
• API Lifecycle Layer: Integrated an explicit parameter deprecation infrastructure to output clean soft-deprecation warnings while preserving structural backward compatibility.
• Hermetic Test Suite: Sealed the internal testing environment against ambient internet variables by enforcing local offline-only execution boundaries (R_CHECK_INTERNET_AVAILABILITY=FALSE).
• Mock Path Optimization: Flattened extended mock JSON directory structures beneath the 100-character POSIX threshold to guarantee absolute compatibility with CRAN tarball filters.

Other Improvements

• Environment Masking: Appended specialized rules to .Rbuildignore to prevent local agent logs (.gemini/), unit metrics (coverage.html), and build directories (lib/) from leaking into release targets.
• Repository Sanitation: Cleaned out empty, legacy directory paths inside the testing footprint to preserve overall repository layout health.
