Version 3.6.5
New incremental garbage collector.
Removed the hard heap size limit (soft heap size limit is still
700/1400Mbytes by default).
Implemented ES5 generic Array.prototype.toString (Issue 1361).
V8 now allows surrogate pair codes in decodeURIComponent (Issue 1415).
Fixed x64 RegExp start-of-string bug (Issues 1746, 1748).
Fixed propertyIsEnumerable for numeric properties (Issue 1692).
Fixed the MinGW and Windows 2000 builds.
Fixed "Prototype chain is not searched if named property handler does
not set a property" (Issue 1636).
Made the RegExp.prototype object be a RegExp object (Issue 1217).
Disallowed future reserved words as labels in strict mode.
Fixed string split to correctly coerce the separator to a string
(Issue 1711).
API: Added an optional source length field to the Extension
constructor.
API: Added Debug::DisableAgent to match existing Debug::EnableAgent
(Issue 1573).
Added "native" target to Makefile for the benefit of Linux distros.
Fixed: debugger stops stepping outside evaluate (Issue 1639).
More work on ES-Harmony proxies. Still hidden behind a flag.
Bug fixes and performance improvements on all platforms.
