Changes in 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)

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("yahoofinancer", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("rsquaredacademy/yahoofinancer")

Development version from rsquaredacademy/yahoofinancer. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-yahoofinancer

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-yahoofinancer

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-yahoofinancer

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
