Version 3.7.1
Achieved 33% speedup in debug-mode tests.
Removed special casing of calls to RegExp test and exec methods with no
argument. Now matches new JSC behaviour. crbug.com/75740.
Return the empty string on cyclic references in toString (ES5
conformance).
Fixed bug triggered by JSBeautifier. crbug.com/100409.
Made Math.random state per-context instead of per-process (issue 864).
Fixed stack traces to skip native functions.
Make snapshots (new contexts) smaller and faster.
Fixed handling of Function.apply for non-array arguments.
Fixed evaluation order in defineProperties to match FireFox.
Fixed handling of non-object receivers for array builtins,
crbug.com/100702.
Multiple fixes to improve compliance with test262.
Fixed compatibility with older Android releases.
Fixed compilation with gcc-4.5.3.
Improved performance of WriteUtf8, issue 1665.
Made native syntax an early error in the preparser.
Fixed issues 793 and 893 relating to Function.prototype.bind.
Improved let, const, Set and Map support and other Harmony features
(behind the --harmony flag).
Changed evaluation order for > and <= to match ES5 instead of ES3.
Bug fixes and performance improvements on all platforms.
