<para>
The way libraries are handled by making the distinction between library pages and files using the concept of "technology namespaces" has improved. Each object has a name composed of a "technology prefix", a double colon ("::"), and the object’​s name. Each library file declares a technology name, which is used as the prefix for all objects in that file. The prefixes are used by XCircuit to track which objects came from which file, regardless of the library page onto which they were loaded. Added support for wires connected to symbol pins remain connected while the symbol is moved. It also expands upon the "Attach-to" function, allowing wires to be (semi-) automatically attached to pin labels or symbol pins. The key macro for "attach-to" (key "A") can also be used like the "wire" function (key "w") to start a wire with its start-point attached to a symbol pin or pin label.
