Sumatra PDF 推出 64 位版

3.1 (2015-10-24)

Changes in this release:

64bit builds
all documents are restored at startup if a window with multiple tabs is closed (or if closing happened through File -> Exit); this can be disabled through the RestoreSession advanced setting
printing happens (again) always as image which leads to more reliable results at the cost of requiring more printer memory; the "Print as Image" advanced printing option has been removed
scrolling with touchpad (e.g. on Surface Pro) now works
many crash and other bug fixes
