Version 1.2.5.
Fixed bug in initial boundary check for Boyer-Moore text search (issue 349).
Fixed compilation issues with MinGW and gcc 4.3+ and added support for armv7 and cortex-a8 architectures. Patches by Lei Zhang and Craig Schlenter.
Added a script cache to the debugger.
Optimized compilation performance by improving internal data structures and avoiding expensive property load optimizations for code that's infrequently executed.
Exposed the calling JavaScript context through the static API function Context::GetCalling().
