The commit message for this revision is wrong. It should have been: Version 1.3.14.
Added GetRealNamedProperty to the API to lookup real properties located on the object or in the prototype chain skipping any interceptors. Fix the stack limits setting API to work correctly with threads. The stack limit now needs to be set to each thread thich is used with V8. Remove the high-priority flag from IdleNotification() Ensure V8 is initialized before locking and unlocking threads. Implemented a new JavaScript minifier for compressing the source of the built-in JavaScript. This Remove non-Open Source code from Douglas Crockford from the project. Added a missing optimization in StringCharAt. Fixed some flaky socket tests. Change by Alexander Botero-Lowry to fix profiler sampling on FreeBSD in 64-bit mode. Fixed memory leaks in the thread management code. Fixed the result of assignment to a pixel array. The assigned value is now the result. Error reporting for invalid left-hand sides in for-in statements, pre- and postfix count expressions, and assignments now matches the JSC behavior in Safari 4. Follow the spec in disallowing function declarations without a name. Always allocate code objects within a 2 GB range. On x64 architecture this is used to use near calls (32-bit displacement) in Code objects. Optimized array construction ported to x64 and ARM architectures. [ES5] Changed Object.keys to return strings for element indices.
