Version 1.3.0.
Allowed RegExp objects to be called as functions (issue 132).
Fixed issue where global property cells would escape after detaching the global object; see http://crbug.com/16276.
Added support for stepping into setters and getters in the debugger.
Changed the debugger to avoid stopping in its own JavaScript code and in the code of built-in functions.
Fixed issue 345 by avoiding duplicate escaping labels.
Fixed ARM code generator crash in short-circuited boolean expressions and added regression tests.
Added an external allocation limit to avoid issues where small V8 objects would hold on to large amounts of external memory without causing garbage collections.
Finished more of the inline caching stubs for x64 targets.
