	expression of which the action is being logged.

    o   The output of loggers 'cellwise', 'simple' and 'expression_logger'
	no contain a 'srcref' column, that gives file name and line number
	of the expression being logged. (thanks to anonymous reviewer B for
	suggesting)

    o   Fixed typos in documentation (thanks to anonymous reviewer B).

                 Changes in version 1.1.4 (2020-03-05)

	object when parsing the R script.

    o   internal changes

                 Changes in version 1.1.3 (2020-01-20)

    o   the 'file' argument in 'cellwise$new' is now called 'tempfile' to better reflect
	it's purpose.

    o   cellwise logger now warns when it encounters a duplicate key (this will corrupt
	logging info).

    o   'run_file' gains argument 'envir'.

    o   new function 'source_file', with behaviour close to 'source'.

    o   stop_log now has 'dump' argument (default: TRUE) and passes ellipsis to $dump() method.

	an existing script.

    o   New function 'run_file', track changes in scripts without '%L>%'

    o   Support for multiple loggers; loggers can now support an (automatic) label
	which is used to distinguish output files when multiple datasets are tracked.

    o   Argument 'log' is replaced by 'logger' in start_log(), dump_log() et al.

    o   Completely new vignette. Removed dependence on knitr.

    o   Completely reviewed the reference manual.

    o   Argument 'stop' of 'dump_log' is now 'TRUE' by default (was 'FALSE')

    o   New logger named 'filedump' dumps data versions to csv.

    o   Function 'stop_log()' will now call '<logger>$stop()' if defined.
