(i.e. grouping by day and then by hour, instead of by day and then by minute)
* GUI tools save their state file in the user's home directory instead of the
current directory.
* The ``parent`` keyword argument of ``HasEnvironment`` (and ``EnvExperiment``)
has been replaced. Pass the parent as first argument instead.
