Version 3.6.1
Fixed a bug in abrupt exit from with or catch inside finally.
Fixed possible crash in FixedDoubleArray::Initialize() (Chromium issue 95113).
Fixed a bug in Page::GetRegionMaskForSpan (Chromium issue 94425).
Fixed a few clang warnings (which -Werror treated as errors).
Performance improvements on all platforms.
