 -   `--freezeParameters name1[,name2,...]` Will freeze the parameters with the given names to their set values. This option supports the use of regexps via by replacing `name` with `rgx{some regular expression}` for matching to *constrained nuisance parameters* or `var{some regular expression}` for matching to *any* parameter. For example `--freezeParameters rgx{CMS_scale_j.*}` will freeze all constrained nuisance parameters with the prefix `CMS_scale_j`, while `--freezeParameters var{.*rate_scale}` will freeze any parameter (constrained nuisance or otherwise) with the suffix `rate_scale`.
     - use the option `--freezeParameters allConstrainedNuisances` to freeze all nuisance parameters that have a constraint term (i.e not `flatParams` or `rateParams` or other freely floating parameters).
-    - similarly the option `--floatParameters` sets the parameter floating (and also accepts regexps, as of version > 9.1.0).
+    - similarly the option `--floatParameters` sets the parameter floating and also accepts regular expressions.
     - groups of nuisances (constrained or otherwise), as defined in the datacard, can be frozen using `--freezeNuisanceGroups`. You can also specify to freeze nuisances which are *not* contained in a particular group using a **^** before the group name (`--freezeNuisanceGroups=^group_name` will freeze everything except nuisance parameters in the group "group_name".)
     - all *constrained* nuisance parameters (not `flatParam` or `rateParam`) can be set floating using `--floatAllNuisances`.
