The speed for LZMA/LZMA2 compressing was increased by 8% for fastest/fast compression levels and by 3% for normal/maximum compression levels. 7-Zip now shows Properties (Info) window and CRC/SHA results window as "list view" window instead of "message box" window. Some improvements in zip, hfs and dmg code. Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in Windows 10 because of some BUG with "Large Pages" in Windows 10.
