Version 3.2 of DropDMG is now available. This is a free update for owners of DropDMG 3.0 that includes the following enhancements:

Highlights

• DropDMG’s user interface is now fully optimized for Macs with Retina displays, as well as multi-display setups.
• DropDMG now renders Retina-quality background images. The source background picture can be a 72 or 144dpi image, a PDF file, or a multi-resolution TIFF file. DropDMG will render a multi-resolution background picture that’s optimized for display on both Retina and non-Retina Macs.
• Rather than adding an application icon to a layout, you now have the option of adding an application icon placeholder. This makes it easy to use the same layout to create disk images for different applications.
• Previously, you could add an Applications folder symlink to layouts by dragging and dropping your Applications folder. There’s now a dedicated button for adding the symlink, to make the feature easier to use and more discoverable.
• Layouts now support a maximum icon size of 512 points (up from 128).
• DropDMG can now create segmented ZIP archives (e.g. .z01, .z02, .zip). Such archives cannot be expanded by Mac OS X’s built-in Archive Utility, but there are free third-party expansion utilities such as The Unarchiver.
• Added the Append version number feature. When imaging or archiving an application or installer, this option will add its version number to the end of the filename.
• Added support for Notification Center (requires OS X 10.8).
• Added the Burn OS X Install DVD feature, an easier way to make your own installer or emergency DVD.
• Streamlined disk image creation by no longer optimizing images for restore that don’t need such optimization.
• Added the ZlibLevel esoteric preference, which lets you set DropDMG to create .dmg files more quickly but with less compression.
• Added the DisableRetinaBackgroundPictures esoteric preference, which lets you create non-Retina background pictures in order to work around a bug in Mac OS X 10.6.

Other Improvements

• DropDMG now tells the system that it can use the integrated GPU, which should reduce battery use on newer MacBook Pros.
• You can now remove the background image from a layout using the contextual menu on the image view.
• DropDMG now offers advice for dealing with “Resource busy” errors.
• Expanded the Making Images With Background Pictures instructions to describe how to make a standard disk image for distributing a Mac application.
• Improved the What information should I include when I report a problem? page.
• Improved the folder name when a folder for segments already exists.
• The documentation now recommends choosing a background picture that’s at least 437 points wide, to account for the Finder’s minimum window width.
• The crash reporter can now make recommendations based on the contents of the crash log.
• Deleting a layout, license, or configuration now moves it to the trash rather than deleting it outright.
• DropDMG itself now has a Retina disk image background, and it shares the layout with other C-Command products.
• After purchasing, DropDMG used to show your user image to indicate that it had been successfully personalized. It now shows a generic checkmark to avoid prompting you for Contacts access on OS X 10.8.
• Added a link to the forum in the Help menu.

Fixes

• Reverted to version 1.2.3 of the Growl SDK to avoid problems with high CPU usage, internal errors, and crashes.
• Fixed a bug where sometimes the layout editor would reset the scroll position.
• Fixed a bug where the tooltips in the main window’s pop-up menu didn’t always update when a configuration was changed.
• Fixed a bug where sometimes packages weren’t wrapped.
• Fixed a bug where sometimes disk images were created without enough space for the background picture or custom icon.
• Layout thumbnail previews no longer change the aspect ratio.
• Fixed a bug where sometimes changes to the segment size in the temporary options dialog didn’t take effect.
• Fixed an issue where, when loading your recent destination folders, DropDMG would sometimes prompt you with a dialog to find folders on unmounted volumes.
• Fixed a bug where TIFF files were not allowed for background pictures.
• Fixed a bug creating images in .cdr format with custom icons or layouts.
• Fixed a bug where there was an extra gray strip next to the action button in the Layouts tab of the preferences.
• Fixed a bug handling errors if the software update failed; if it succeeded, the .dmg file is now deleted.
