As usual Chrome 50 contains a number of fixes and improvements, but the biggest change in this latest version is the end of support for Windows XP, Windows Vista, and OS X 10.8 or older operating systems.
Bugs in the Universal XSS, Pdfium JPEG2000 decoding, and out-of-bound writes in V8 have been solved by external researchers claiming rewards which add up to $32K+. Internally, Google has secured fixes from internal audits, fuzzing and other initiatives.
