Fixed bug where saved Automator workflows didn’t use the proper configuration when running on Mac OS X 10.5.2.
Fixed bug where certain disk images of application files created on Mac OS X 10.5.2 would mount on 10.3, but the Finder would refuse to open them. (The contents were intact and accessible from other applications.)

2.8.4—January 21, 2008

Fixed a regression in version 2.8.3 where DropDMG would delete the source file/folder if you were creating a segmented disk image next to the source and there was not enough disk space.

2.8.3—January 8, 2008

Fixed bug where a .dmg file would not mount on Mac OS X 10.3 and earlier if you created it on an Intel-based Mac running Mac OS X 10.5 and the image contained just a single package file (e.g. an application).
Fixed bug where Append Current Date didn’t work properly when the original file/folder had a very long name.
Fixed bug where images converted from Zip archives were owned by root.
Faster at creating images of packages when running on Mac OS X 10.5.
Fixed bug restoring the selected row after editing a configuration name.
Carriage returns are no longer allowed in configuration names.

Fixed bug where DropDMG would sometimes return an incorrect destination path back to a script.

2.8.1—July 31, 2007

If the destination folder is inside the source folder, DropDMG will now report an error and ask you to pick a different folder, rather than silently using Next To Source.
Fixed bug that could cause a crash after verifying or mounting an image.
DropDMG now accepts .ISO images (uppercase extension from the Windows world) and treats them as .iso.
Fixed bug where DropDMG wouldn’t let you quit after certain types of burn failures.

Fixed bug where the Software Update checker didn’t always re-check for new updates.
Modernized the crash reporter code.
Updated Dutch and Italian localizations.
Fixed help book icon.

2.8—April 4, 2007

Improved compatibility with pre-release versions of Mac OS X 10.5.
Passphrases are now set in a separate dialog rather than directly in the preferences window, and this has been combined with the old Confirm Passphrase feature. This makes it easier to verify a passphrase when you enter it.
DropDMG now accesses the keychain only when necessary, so it won’t prompt you to unlock the keychain if you’re creating an image that doesn’t have a passphrase.
The Software Update checker now works behind an HTTP proxy, and the auto-updater is compatible with FileVault.
Reorganized the manual and added Burning Backups of CDs/DVDs and Transferring Files Securely sections.
When creating an image of an application or installer package, DropDMG no longer includes file extension in the image name.
Worked around -39 error from hdiutil when converting very large images with lots of files.

Fixed bug when converting multiple archives simultaneously using StuffIt Expander.
Rewrote the Software Update feature. When a new version is available, it can now show you the release notes. DropDMG now downloads the new version itself, rather than relying on your browser. The Download & Install button will cause DropDMG to auto-update itself to the latest version.
Added recommended segment sizes to the manual and tooltip.
If no windows are open when you click on DropDMG’s icon in the Dock, it will now open The Status Window.
The Volume Name field is ignored when creating a device image, so it’s now disabled in that case.
Aliases in the Recent Folders folder are now created with icons.
Dates in the log now follow the user’s preferred short format.
Fixed bug where it was possible to change the destination folder without the active configuration changing to (custom).
Fixed bug where clicking the Confirm button could change the configuration to (custom).

Errors encountered while preparing to create an image are no longer reported twice.
Mounting errors are now displayed properly.
Improved display of keychain errors.
Added Danish localization and updated the other localizations.

2.7.3—October 25, 2005

You can now view and set the current configuration from DropDMG’s Dock menu.
Added “Expand Disk Image” Automator action, which replaces a disk image with a folder containing the image’s contents. You can create an “Expand Image” contextual menu item in the Finder by creating a single-step Automator workflow with this action and saving it as a Finder plug-in.
Problems with the destination folder are now reported using the “choose destination” sheet instead of in a separate alert.
The software update feature now shows a sheet instead of an alert when there’s a new version, so it won’t interfere with scripted operations.
Fixed regression where DropDMG would complain at launch if one of the configurations’ destination folders didn’t exist.
Fixed bug where DropDMG would waste CPU time animating an off-screen progress bar after finishing an operation.
Added Technical Support & Feedback item to Help menu.
Updated eSellerate engine and PCRE.

2.7.2—September 22, 2005

You can now drag and drop anywhere on DropDMG’s status window, rather than just on the top part of it.
Fixed bug where DropDMG was incompatible with StuffIt Expander 10.
DropDMG now reports an error if you specify a destination folder that doesn’t exist, rather than silently picking a fallback folder.
Better error messages when DropDMG doesn’t find a file in the expected place.
The command-line tool now treats the empty string as an invalid destination folder instead of (as with AppleScript) treating it as a flag to indicate that the user should be prompted to specify a folder. This should reduce unexpected behavior when running DropDMG via a shell script that doesn’t properly quote the command-line arguments.
Errors during burning are now presented using a sheet, rather than just being logged.
No longer shows an error message if you try to install the command-line tool and then cancel out of the authorization dialog.
Updated the Italian localization.

Fixed regression where the command-line tool didn’t work on Mac OS X 10.3.

2.7—August 15, 2005

Added commands for burning folders, files, and disk images. As a shortcut, you can initiate a burn by dragging and dropping onto the status window or the DropDMG icon while holding down the Shift key. Hold down Option and Shift when dropping a disk image if you want to burn the image as a file, rather than burning its contents.
Added smooth determinate progress bars for the longer steps when creating disk images (requires Mac OS X 10.4).
Progress windows now have a cancel button, an icon showing the kind of file that’s being created, and an icon and title bar menu that show the source file or folder.
Added Quit When Done option; if selected, DropDMG will quit when there are no longer any image, archive, or burn operations in progress.
The status window now has a pop-up menu for displaying and changing the current configuration.
Better creation of device images from multi-partition devices.
Progress windows are now tiled (so they don’t overlap), and DropDMG is better at remembering where you like to position them. Dragging a progress window sets the preferred location for new progress windows.
The following File menu commands can now accept multiple selection, so that you can operate on more than one image at a time: Fix Image…, Get Image Info…, Mount Image (with Owners)…, Verify Image Checksum….
Improved scriptability. You can now access DropDMG’s windows, menus, and other interface elements from AppleScript. You can also access the current imaging and burning operations and cancel them. You can initiate burns from AppleScript.
The Automator action is now a universal binary.
The dropdmg command-line tool now properly communicates with the DropDMG application when running on Intel.
Fixed bug where image creation could fail with an error when creating an image on an external volume, depending on the lengths of the source and destination paths.
Fixed regression where file packages weren’t wrapped when DropDMG was running with root access.
Fixed bug where Sanitize for Servers didn’t account for file names that were entirely non-ASCII characters.
Fixed bug where DropDMG would sometimes fail to remove an extra folder layer when converting from Zip format.
Fixed bug where the Edit Configurations window allowed multiple selection.
Fixed bug that could cause a crash when creating a disk image if the OS reported an error at exactly the wrong moment.

Adjusted the way the remaining demo time is displayed.
Updated Czech, Dutch, French, and Italian localizations.

2.6.3—June 22, 2005

Fixed regression where DropDMG would report an error when converting a .dmg image to read-write format.
Fixed regression where the license agreement editor didn’t work on Mac OS X 10.3.

2.6.2—June 20, 2005

Fixed regression where DropDMG would halt with a permissions error when creating an image from a lone file and running on Mac OS X 10.3.

2.6.1—June 20, 2005

DropDMG can now create .dmg disk images that are internally compressed using bzip2. These images can only be mounted on Mac OS X 10.4 and later, but they are often much smaller than zlib-compressed disk images.
Made various optimizations for faster disk image creation.
Added Mount Image (with Owners)… command. This lets you copy files off an image with their Unix ownership intact. (Normally, when you let the OS mount an image, it pretends that all the files are owned by you.)
The Add Agreement… command is now enabled even when the License Agreements window isn’t open. This should prevent people from being confused about how to create a new agreement.
The Append Current Date option is now applied only when creating new images, not when converting.
If you tell DropDMG to segment an image/archive, and it ends up being smaller than the segment size that you chose, DropDMG will no longer wrap the output files in a folder (since there’s only one).
The keyboard shortcut for Open Configurations is now Command-Option-,.
Worked around some Tiger issues that could cause DropDMG to halt part way through creating an image.
Worked around bug in Tiger where .bz2 and .gz files would have .dmg type and creator codes, which could cause problems opening them.
Worked around Tiger issue so that it’s once again possible to remove a license agreement by converting (using None as the agreement).
Better cleanup if there’s an error creating the image.
DropDMG no longer complains when there’s no default keychain.
.mailbundle folders are now treated as packages, even though technically they aren’t.
Filename uniquing is now smarter when there are two extensions. So, for example, you’ll end up with Foo-1.tar.bz2 instead of Foo.tar-1.bz2.
Fixed bug where sometimes custom icons didn’t work if you created multiple images simultaneously.
Fixed bug where images created from volumes couldn’t be Internet-enabled.
Fixed bug where dragging a folder onto the Preferences window (to change the destination) didn’t change the selected configuration to (custom).
Fixed bug where StuffIt X and Tar were always enabled in the contextual menu.
Fixed bug where Tar archive creation wasn’t package-savvy.
Fixed bug where Zip archives of single files contained an extra folder layer.
Added --version switch to the dropdmg tool.
The license agreement editor is faster at auto-saving any changes that you make.
The demo reminder window updates the number of days remaining if you leave DropDMG running for days or weeks at a time.
Fixed bug where DropDMG could get into a state where it was permanently waiting for other operations to complete.
Fixed bug that could cause a crash when using the Instant Purchase feature.
Updated French and Italian localizations. Added Dutch localization.

Worked around the OS to prevent DropDMG from sometimes being dropped from the Services menu.
Window order of the Preferences window is preserved when closing the Configurations window.
Updated to eSellerate Engine 3.6.1.
Improved serial number name entry.
The Apple Help is now multiple linked pages, rather than a single page, so you can now use Help Viewer’s search box.

2.5.3—February 7, 2005

Fixed bug where some valid files weren’t choosable in the open dialogs.
Update Czech localization.
Improved name and serial number entry.

2.5.2—January 24, 2005

Fixed bug where the volume permissions would be incorrect when making an image directly from a file.

Updated Czech localization.

2.5.1—January 11, 2005

Fixed bug where the BinHex and MacBinary encoders didn’t preserve non-ASCII filename characters.
Fixed bug where special handling of file packages was sometimes disabled.
When there are many simultaneous operations, DropDMG will queue some of them. This improves performance and works around some hdiutil limitations.
Added Always Run With Root Access option.
When prompting for file and volume names, DropDMG is smarter about when to remove the file extension in its suggested name.
Relaxed requirement that the source item’s containing path doesn’t contain a slash (colon).
Now sets the owner and permissions of the disk image root to match the source folder.
Added help button to the preferences window.

Added support for .cdr (DVD/CD-R master) images.
DropDMG can create a custom icon for the mounted image.
You can now save named Configurations of DropDMG’s preferences. By switching between different configurations, you can instantly recall different combinations of options.
When you ask DropDMG to create an image from a volume, it automatically creates a device image, an exact copy of the volume, which is bootable (if original volume is).
DropDMG now has a system service, which lets you easily create images/archives from items selected in the Finder, without DropDMG being open or in the Dock.
Added Mount Image At… command, which lets you mount images at arbitrary locations in the filesystem, rather than on the desktop.
Add Ask Later option, which makes DropDMG prompt you for a destination folder each time it needs to save an image or archive.
Added Confirm button to let you verify a passphrase after typing it.
DropDMG can now process multiple commands from AppleScript or the command line at the same time.
Uses much less memory when computing folder sizes.
Launches faster.
The license agreement editor now supports find and replace.
The log and image info windows now support the Find command.
Lots of minor interface tweaks (window zooming, folder abbreviations, checkbox and button enabling etc, keyboard shortcuts, new window manipulation menu commands.).
When creating encrypted images, the passphrase is now sent to hdiutil securely using a pipe instead of on the command line.
A Cancel button is now available when you’re prompted to enter image and volume names.
When creating a segmented image or archive, the segments are now placed in a newly created folder.
Normalizes serial number case when personalizing, to make it less error-prone.
You can hold down the Option key when clicking OK to dismiss multiple temporary preferences sheets at once.
If the chosen destination folder is read-only, DropDMG now prompts for a new destination folder rather than aborting with an error.
When you try to delete a license agreement, DropDMG now shows an alert sheet to make sure that’s what you really meant.
The returning immediately AppleScript parameter is no longer needed and has been removed. If you want the AppleScript command to return before the operation is complete, use a standard AppleScript with timeout block.
The create image AppleScript command now returns the path of the created image/archive. The command-line tool prints the path to standard output.
The When Imaging a Package option has been removed from the preferences, but is still available via AppleScript and the command line.
When creating an image, DropDMG now preserves ownerships and permissions, rather than just permissions. (This will not be evident unless you uncheck Ignore ownership on this volume after mounting the image.)
Fixed bug where you’d have to authenticate more often than necessary.
Fixed bug where relative paths did not work with the dropdmg tool’s --destination switch.
Fixed bug where top-level symlinks were resolved instead of being copied as links.
Fixed bug where it was possible to rename a license agreement, giving it the same name as another agreement.
Fixed bug where DropDMG would sometimes return a “permission denied” error when calculating the space necessary to image a folder. Now, it will instead prompt for an administrator password.
Fixed bug where sometimes you’d be prompted for a password after already entering one in the preferences sheet.

2.2—October 16, 2003

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.

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.

2.1.1—July 21, 2003

Fixed bug where converting a .dmg file created by Disk Copy to .img or .smi caused the .dmg file to remain in use so that it couldn’t be deleted, or its volume ejected.
Adding license agreements to images now works on Panther.
Fixed open/save dialog prompts to be more in line with the Aqua Human Interface Guidelines.

2.1—April 24, 2003

Remembers recent and favorite destination folders.

Added a returning immediately scripting parameter. This lets you control whether the script waits for DropDMG to finish creating the image.
You can now use tildes in paths when scripting DropDMG.
Suggests localized image names, when possible, and omits hidden extensions, so that you don’t end up with, e.g., a .app.dmg file.
The license agreement editor is much more responsive.
You can set the encoding from the DropDMG Status window’s contextual menu.
Can now encode .dmg images with MacBinary.
Updated the MacBinary encoder for compatibility with Apple’s JDK 1.4.1. (In the latest JDK, Apple removed support for JDirect, which the old MacBinary encoder relied upon.)
Fixed bug where DropDMG couldn’t image a folder with more than 100 or so top-level items.
Worked around problem where some .dmg images created with Disk Copy could not be converted to .img or .smi.

The DropDMG Status window is closable (if you register).
License agreements remember their window positions across renames.
The License Agreements window is printable.
The DropDMG Status window zooms to a reasonable width instead of the whole screen.

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.
New application icon.
Compiled with GCC 3.
No longer calls thread-unsafe parts of Carbon from child threads.
Prevents the user from making a read-write image with a license agreement, rather than stopping midway through with an error message saying that this wasn’t possible.
The status window no longer looks as though it will accept the drop when you try to drop a .dmg file that doesn’t need metadata fixing.
Changed File menu text and keyboard shortcuts to more closely match 10.2’s Disk Copy.
The about box and registration window now use the design first seen in SpamSieve.

Changes to the segment size take effect immediately; you no longer have to type Tab or Return to commit them.
The status window updates faster.

1.7—August 12, 2002

Added support for license agreements. License agreements support rich text and may be localized.
The image destination path is now stored abbreviated with a tilde, if possible. This should help people who have multiple boot partitions.
The log is printable.
Finer-grained progress bar and status text.
If adding the requisite filename extensions would make the requested image name longer than the limit, DropDMG will now quietly truncate the name rather than stopping with an error.
NDIF images are now created with filenames of 31 characters or less, so that there won’t be any name mangling when they’re viewed in Mac OS 9.
DropDMG now truncates .dmg volume names to 62 characters and .img volume names to 27.
Fixed bug where DropDMG could deadlock after certain kinds of errors.
Fixed bug where DropDMG sometimes didn’t detect filename collisions until after it started making the image.
Fixed bug where DropDMG would overwrite pre-existing .dmgpart files if the first segment was not present and the newly created image happened to have the same name.
Renamed some File menu commands.

1.6—July 15, 2002

Option to make images auto-open. When you mount an image, its window opens in the Finder. Previously, there might have been no visual indication that the image had mounted, depending on how the user’s Finder preferences were set.
The status window has a contextual menu for quickly changing common preferences.
You can optionally set the names of the image file and volume, instead of having them based on the name of the folder.
Documentation is now included in Apple Help (HTML) format as well as PDF.
Contains a menu command for clearing the log.
No longer fails when copying files for which the user only has read privileges. Previously, DropDMG would copy the file and permissions and then report a permissions error when it tried to set the catalog information of the copy, which wasn’t writable.
The radio buttons for selecting where the image will be saved are no longer linked to the image destination text field. That is, tabbing of the text field no longer affects the radio button’s selection, making the preferences more friendly for keyboard navigators.

1.5—May 2, 2002

Multi-threading—DropDMG can create more than one image at a time, and the interface remains responsive.
Can divide large images into multiple segments of fixed size.
Creates uncompressed read-only images, which often compress better with GZip than internally-compressed image files do.
Creates read-write images.
Encodes Mac OS 9 .img images with MacBinary so that they can be transferred on the Internet.
The status window displays a log that shows all the completed operations and errors.
The status window now shows all the format options that are in effect.
Faster copying of Mac metadata.
Worked around Apple bug that sometimes caused errors when creating large images. hdiutil crashed when expanding sparse images.
Fixed bug where DropDMG mistakenly resolved symlinks when copying Mac metadata. This had caused some metadata not to be copied, and also caused image creation to fail if the user didn’t have write access to the original file.
Fixed regression where DropDMG sometimes didn’t complain when the destination folder was inside the source folder.
Tries several times to eject images, rather than giving up immediately.
More detailed reporting of file copy errors.
More accurate reporting of what state the image creation process is in when errors occur.
Mailing list for version announcements has a Web interface.

1.3.1—March 11, 2002

You can now create images by dragging and dropping folders into the status window.
The status window’s indication of the progress is more accurate.
Fixed regression in which images couldn’t be created on non-boot volumes.
Fixed regression in which images couldn’t be created in ~/Desktop if the destination folder had never been manually set.

1.3—February 25, 2002

You can now choose whether images are saved next to the source folder, or in a user-defined folder.
Volume images are now created in ~/Desktop by default (instead of /Volumes).
Resolved problem in which DropDMG tried to replace invisible system files on the image, if the source folder contained items with the same names.
The format parameter is now optional when creating images with AppleScript.
Notifies the system after fixing an image’s type and creator.
Fixed bug in which DropDMG would report the wrong file as the cause of a copy error.
The keyboard loop in the Preferences window should work again.
The status window no longer flickers when the program first opens.
The distribution is smaller, since the manual uses fewer images.

1.2.1—February 11, 2002

Uses Carbon to preserve Finder info (e.g. the locked, stationery, and custom icon bits) when copying files.

1.2—February 3, 2002

All options are now available from the scripting interface.
No longer requires Mac OS X’s optional “BSD Subsystem” installation.
Optionally post-compresses DMGs with GZip.
Fixes type and creator codes of DMGs.
Preferences window is easier to use; now, enablement is only tied to the Image Format radio buttons.
Capitalizations now follow the Aqua Human Interface Guidelines.

1.1—January 28, 2002

Supports ADC and NDIF compression for compatibility with Mac OS 10.0.x and Mac OS 9, respectively.
Supports encrypted compressed images in the zlib and ADC formats.
Optionally detects packages so that you end up with a mounted image containing the package instead of a mounted image that the Finder thinks is a package.
Copies locked files to images (instead of stopping with an access error).
Images’ logical sizes are smaller; this should slightly reduce their physical sizes and reduce mount times.
Accepts drops of all file types (including packages); if DropDMG doesn’t know how to handle a dropped file it will just ignore it.
The Make Image From Folder… menu command lets you choose packages and subfolders of packages (instead of just vanilla folders).
Minor UI tweaks.
