Version 3.9.8

Fixed memory leak and missing #include in StartupDataDecompressor (issue 1960).

Renamed static methods to avoid shadowing virtual methods and fix Clang C++11 compile error.

Fixed sequence of element access in array builtins (issue 1790).

Performance and stability improvements on all platforms.
