Version 3.15.12
V8_Fatal now prints C++ stack trace in debug mode.
Added HTML-based tick processor.
Continued implementation of Object.observe (V8 issue 2409).
Fixed V8 issues 2243, 2340, 2393, 2399, 2457.
Fixed Chromium issues 125308, 165637, 166379, 166553.
Performance and stability improvements on all platforms.
