the optional version number placed after the cookie string is higher than
the version of the :file:`modulecmd.tcl` script in use.
* Doc: alphabetically sort installation option in :ref:`INSTALL` document.
* Update the :instopt:`--enable-quarantine-support` installation option to
control a :mconfig:`quarantine_support` configuration option. When this
option is enabled, the :subcmd:`autoinit` sub-command produces the shell
code for the :command:`module` shell function definition with quarantine
mechanism support. When disabled, code is generated without quarantine
support.
* Install: installation option :instopt:`--enable-quarantine-support` is set
off by default.
* Introduce the :envvar:`MODULES_QUARANTINE_SUPPORT` environment variable to
control the :mconfig:`quarantine_support` configuration option once Modules
is installed. To enable the quarantine mechanism,
:envvar:`MODULES_QUARANTINE_SUPPORT` should be set to ``1`` prior Modules
initialization or :mconfig:`quarantine_support` configuration option should
be set to ``1`` in the ``initrc`` configuration file.
* Quarantine mechanism code in the Modules shell initialization scripts is now
always defined and mechanism always applies if some environment variables
are defined in :envvar:`MODULES_RUN_QUARANTINE`.
* Code in the :file:`modulecmd.tcl` script to restore environment variables
put in quarantine is now always generated and applies if the
:envvar:`__MODULES_QUARANTINE_SET` environment variable is set to ``1``.
This variable is set by the Modules initialization script prior calling the
:subcmd:`autoinit` sub-command or by the :command:`module` shell function if
it has been generated with quarantine support enabled.
