DropDMG 2.0 is now available.

DropDMG is the easiest way to create ".dmg" and ".img" disk images on Mac
OS X. It can encrypt images and post-process them with GZip, BZip2, or
MacBinary. It can create images with rich-text license agreements. It also
supports segmented images and images that auto-open when you mount them.
All the options are available from AppleScript.

New in this Version:

* Converts dropped images to the format specified in the preferences
when you hold down Control-Shift.
* Hold down Option when dropping a folder or image to specify
settings to be used for that item (temporarily overriding the
preferences).
* Makes self-mounting NDIF images (SMIs). This is the only kind of
image that supports license agreements on both 9 and X.
* Creates smaller zlib-compressed images when running on 10.2 and
later. (The images are still compatible with 10.1's Disk Copy.)
* You can now choose to post-compress with BZip2 instead of GZip.
BZip2 is slower than GZip but creates smaller files.
* Improved the layout of the preferences window.
* Faster at copying files to the image when running on 10.2 and
later.
* Worked around 10.2 bug that caused errors when a file or folder
name contained a slash (as shown in the Finder).
* Worked around OS X bug that prevented copying files larger than
about 1 GB.
* See the manual for the full list of changes.
