Itcl 4.0.4 fixes a large collection of bugs and flawed designs. See the ticket
systems and timelines for a full accounting. A great deal of progress has been
made to make Itcl 4 a functionally equal replacement for Itcl 3. If you've
delayed migration due to lack of compatibility, it's time to try again. This
is the same Itcl release that is bundled with Tcl 8.6.5.
This port provides the 4.x series of [incr Tcl], an object-oriented extension
to Tcl. While the 3.x series provided by lang/itcl works with Tcl 8.5, the
4.x series is targetted at Tcl 8.6.
