* Fix "Loops detected" assertion when model exceeds 4GB. [David Hewson]
* Fix display %m names inside named blocks.

==========================

**Minor:**

* Add --trace-depth option for minimizing VCD file size. [Emerson Suguimoto]
* With VL_DEBUG, show wires causing convergence errors. [Mike Shinkarovsky]
* Fix isolate_assignments when many signals per always. [Mike Shinkarovsky]
* Fix isolate_assignments across task/func temporaries. [Mike Shinkarovsky]
* Fix $display's with array select followed by wide AND. [David Hewson]
