 - yet another fix for Shapely 2.0 deprecation warnings
 - updated the `join_geometry` and `join_excellon` Tcl commands format to follow the format of other commands
 - updated the `isolate`, `cutout` and `geocutout` Tcl commands and now they yield multigeo Geometry objects
-- fixed an issue in `panelize` Tcl command where the some parameters (`spacing_columns` and `spacing_rows` where forced into integers where correct was to keep them as floats)
+- fixed an issue in `panelize` Tcl command where some parameters (`spacing_columns` and `spacing_rows` where forced into integers where correct was to keep them as floats)
+- fixed a performance issue in `panelize` Tcl command: when panelizing a Geometry object the total solid_geometry was calculated for each tool, but it was enough to be calculated once
