• algorithms now built separately for various CPU features, and loaded accordingly
• added a Cancel button, visible during hashing
• standalone version, associated with sumfiles (optional)
• windowed, resizable instance startable from context menu (optional)

• more conforming sumfile format (Unix line endings, forward slashes, optional)
• BOM support for sumfiles
• base64 support for sumfiles (checking only for now)
• corz .hash checking and exporting
• SFV checking and export
• now we have an icon
• lots of new settings
• VirusTotal lookup button (thanks to ProcessHacker)
• option to automatically enable algorithms based on sumfile or clipboard hash
• update check button
• DPI awareness
• always using shell font (eg. chinese is now antialiased)
