The custom toString methods - defined for all modules in the Uize base module, and defined for all classes and instances of classes in the Uize.Class module - have been eliminated.

These custom, overridden versions of the toString method were originally designed to provide developers with a quick way to get a summary for instances, classes, and modules for displaying in alert statements as a troubleshooting aid, and were implemented back in a time when the debugging tools built into browsers (especially IE6) were less mature. Things have improved a lot since then in the area of Web inspectors, especially in more recent versions of MSIE.

As a result, most modern debugging involves logging to the browser's console using console.log or console.dir calls, and so the summary behavior of the overridden toString methods have become under-utilized and their implementations represented unwelcome extra code bloat. Consequently, they have been eliminated from the Uize and Uize.Class modules. The summary behavior can still be accessed through the Uize.Util.Debug.summary static method of the new Uize.Util.Debug module.

This change was deemed low risk and is, therefore, not backwards compatible in order that developers can immediately benefit from the code size reduction.
