  from files, previously exported from the shell, into the shell's database

  default shell. The behavior of the command depends on the shell's
  configuration

  the shell should use the system's default shell or not

Changed

• Updated the shell's help entries
• Updated look of list of available subcommands. Now there are more colors.
• Redesigned the look of the output of command options list. Removed
  information about types and default values for options and made information
  about their values, more human-friendly
• BREAKING: Redesigned the command options set. Instead of setting the
  name and value of the option to set by its arguments, the command is now a
  form similar to setting an alias or a variable
• BREAKING: Redesigned the command options reset. Same as above, instead of
  setting the name of the option to reset by its argument, the command will
  ask for the name after executing it. Resetting of all options is done in
  the same way as it was
• Moved information about the last command's error code before information
  about the current directory in the shell's default prompt
• Commands alias delete, alias show, alias edit can now be executed
  without entering the index of the alias. In that situation, the user will
  be asked for the index of an alias from their list
• Commands completion edit, completion delete, completion show can now
  be executed without entering the index of the completion. In that situation,
  the user will be asked for the index of a completion from their list
• Commands plugin remove, plugin enable, plugin disable, plugin show
  can now be executed without entering the index of the plugin. In that
  situation, the user will be asked for the index of a plugin from their list
• Commands variable delete, variable edit, variable show can now be
  executed without entering the index of the variable. In that situation, the
  user will be asked for the index of a variable from their list
