Changes in version 0.9.0 (2024-03-28)                  

    o   Now supports reference data in rules, specified by the parameter 'ref' in 
	the 'modify' function. 

                 Changes in version 0.8.0 (2023-04-07)                  

    o   Now supports rule-wise logging of changes by integration with the
	'lumberjack' package.

    o   'modifier' now reads rules and metadata from data frame

    o   Fix: constructions with single values such as 
	if (is.na(x)) x <- mean(x, na.rm=TRUE) now work correctly.

    o   Fix: in blocks following a condition, such as 
	if (x < 0){ x <- 10; y <- 1}, the expression y <- 1 would not
	be executed because the first expression in the block modifies
	the value of the condition. [i.e.: if(c){a;b} is NOT equal to
	if(c){a}; if(c){b}.]

    o   Vignette updated and now rendered with 'simplermarkdown'

    o   Improved documentation (thanks to Jordi van Dooren)
