with a cookie, and that caused the connection attempt to fail. This affected \ 
getSymbols(), getDividends(), and getSplits(). Thanks to several users for \ 
reporting, and especially to @pverspeelt and @alihru for investigating potential \ 
fixes! #358

    Update getSymbols.yahooj() for changes to the web page. #312

etc.Thanks for Karl Gauvin for the nudge to implement them.

functions that import data. Thanks to Ethan Smith suggestion and PR. #280 #281

    Make getQuote() robust to symbols without data, so it does not error if one \ 
or more symbols are not found. Also return quotes in the same order as the \ 
‘Symbols’ argument. Thanks to Ethan Smith feature request and PR. #279 #282 \ 
#288

    Handle semicolon-delimited symbol string handling to main getQuote() \ 
function. This makes getQuote() consistent with getSymbols(). Thanks to Ethan \ 
Smith suggestion and PR. #284 #285

date labeled as the ex-dividend date. Thanks to @matiasandina for the report. \
