• Addresses rendering issue in Microsoft Edge for PDF documents with backgrounds created using various third-party publishing tools.
• Addresses issue that decreases the Universal CRT’s performance in the _gcvt and _gcvt_s functions.
• Addresses issue in which the output to a file or pipe was fully buffered in the Universal CRT for the standard error (STDERR) stream.
• Addresses issue in the Universal CRT by adding the “x” access mode flag to support the fopen() function.
