The Uize.Data.identical static method of the Uize.Data module has been improved with the addition of a new variation that allows comparison options to be specified in an optional optionsOBJ parameter.

One new comparison option allows for comparing only the structure of two objects to see if they are identical, regardless of property values for either of the objects. Another new comparison option allows for testing that values for properties of both objects are equal, but not according to a strict equality match, so the object {prop:1} would be considered identical to the object {prop:'1'} when using this option. Finally, the new allowConjoined comparison option lets you specify whether or not the two objects being compared may reference the same shared object at any level of their structure.

The Uize.Data.identical and Uize.Data.clones static methods have been optimized for performance.

The new Uize.Data.getTotalKeys static method lets you get the total number of keys in an object, without the cost of actually building an array of all the keys.
