v2.0.0
Added ability to backfill ticker data with oldest ticker from the fund share classes.
Some notes on the backfill capabilities:
- This is a breaking change as the 'ticker' column was added to the returned dataframe which will cause issues with any previously cached csv data files.
- To not lose existing cached data, write a script to read in the existing csv file, add a ticker column and set the value to the ticker, save the results back into the same file.
- If you don't need to preserve your cached data, the easiest option is to just delete the current cache files and let the cache rebuild.
- The backfill crosswalk file only maps Vanguard mutual funds.
