Plot(): Character string versions of a date as in a variety of forms as digits, such as "08/18/2024", are now by default converted to variable type of Date. However, this conversion is inherently ambiguous, so the time_format parameter is provided as a means to provide the precise format if needed, including other formats such as "August 18, 2024". Also, a sequence of four-digit integers within the usual range of dates will also convert automatically to a variable of type `Dates.
STL(): A wrapper for Base R stl() that provides additional information and utility:
Date as the x-variable and the time series values as the y-variable instead of an R time series.Date.BarChart(), Histogram(), Plot(): If the x- or y- axis values in the resulting plots all end in 000, then the 000 is replaced with a K, such as 120000 plotted as an axis value of 120K.

ANOVA(), BarChart(), Histogram(), Plot(), Regression(), ttest(): A tibble that is not in the user workspace, instead in a package, is now properly converted to a standard R data frame upon which the internal function's code depends, which also permits more flexibility in the packaging of data in general to these functions, such as with the pipe operator.
ANOVA(): Overall p-value now available for the one-way ANOVA as the statistic in an output object, called p_value, such as output object a$p_value in a <- ANOVA( ... ).
