Version 2.2 of DropDMG is now available.

This is a free update that includes the following changes:

• Added dropdmg tool for creating images from the command-line.
• You can now create an image from a file by dropping it on DropDMG; you no longer have to “wrap” the file in a folder.
• You can now specify the passphrase for an encrypted image via AppleScript.
• Can save a passphrase in the system Keychain, so that you can encrypt multiple images using the same passphrase, without having to keep typing it.
• Lets you authenticate as an administrator to copy protected files to an image.
• Images can now be encoded with BinHex.
• You can now drag a file or folder onto the preferences to set the destination.
• License agreements can use non-roman characters.
• Added Get Image Info… command.
• Added Verify Image Checksum… command.
• Added crash reporter.
• Added software update version checker.
• Faster MacBinary encoding.
• Uses less memory when dealing with lots of files.
• The destination pop-up menu now includes icons.
• Rather than nagging when unregistered, DropDMG now has a 30-day/20-launch trial period.
• Fixed bug that caused an error when creating more than one self-mounting image simultaneously.
• Fixed bug where DropDMG never prompted for volume and image names when you used a temporary preferences sheet.
• DropDMG now requires Mac OS X 10.2 or later.
