The following was posted on the DropDMG blog:
Version 3.1 of DropDMG is now available. This is a free update for owners of DropDMG 3.0 that includes the following enhancements:
- DropDMG is much faster at creating large disk images under most circumstances, and it now compresses disk images a bit more tightly. Added the Use less temporary disk space preference, so that you can make DropDMG operate in the older, slower mode if your destination volume is running out of space.
- Disk image layouts can now contain text boxes, with your choice of fonts, styles, colors, and shadows. Thus, it’s no longer necessary to fire up a graphics program to update the text in your background picture.
- Layout text boxes can contain placeholder variables, which DropDMG will replace when creating the disk image. For example, if your disk image contains an application (e.g. DropDMG.app), the text ${APP_SHORT_VERSION_STRING} will be replaced by the marketing version of the application (e.g. 3.1).
- The Mount Image… command now has a Shadow file
option that lets you mount a read-only disk image as read-write. Any changes made to the mounted image will be written to the adjacent shadow file. This can be useful, e.g. if you want to use Spotlight to search a read-only disk image. - DropDMG now supports license agreements localized in Arabic, Greek, Russian, and Ukrainian. - To ensure that background pictures display properly in the Finder, DropDMG now reports an error if you give it a picture file that’s not 72dpi.
- Many operations when editing a disk image layout are now undoable.
- The license agreement editor text view now displays line breaks in the same places as the text view that the system uses when mounting the disk image.
- The Preferences window now supports full screen mode (requires Mac OS X 10.7).
- Added the Burning a Lion Installation DVD section to the manual.
- Fixed a bug where, when creating an encrypted disk image with no specified passphrase, DropDMG sometimes failed to prompt for one.
- Fixed a bug where creating a new language for a license agreement appeared to do nothing if the license’s name was in edit mode.
- Fixed a bug where the configuration/layout/license lists didn’t properly update if you added an item while you were renaming another item.
- Fixed a bug where the source size reported in the log when mounting a disk image only counted the first segment.
- Fixed a bug that could cause DropDMG to create a .tar.bz2 archive when you requested .tar.
- Fixed alignment of license button text fields.
- Fixed a bug with re-personalizing the application via URL.
