tidyfinance 0.3.0 (2024-07-23)
New features
- Added support for all available Fama-French datasets (check via
list_supported_types()). All type names are created from a string cleaning algorithm and are hence more consistent. We kept implicit support for legacy type names to avoid breaking existing code.

download_data_stocks().
- Added support for
wrds_compustat_quarterly.
Bug fixes
- CRSP monthly data always contains the historically accurate stock characteristics instead of the oft misleading most recent information.
- Consistently implemented the
additional_columns option for CRSP and Compustat instead of having the error prone option to pass columns via ....
- Added replacement of
-999 by NA in Fama-French types, which was missing in the initial implementation.
Improvements
- Refactored the column name cleaning procedure in
download_data_factors() to support all available column names in the Fama-French universe.
- Made all
start_date and end_date optional with a message to user which dates are used as defaults.

- Synchronized
date column and its references across WRDS types (see corresponding vignette for more information).

tidyfinance-package.R file.
- Reformatted DESCRIPTION and roxygen comments for more consistency with
tidyverse style.
