OmniDiskSweeper Message of the Day

OmniDiskSweeper is now a 64-bit app, which means it can handle much larger sets of files.
The minimum system requirement is now 10.6.8 (Snow Leopard).
File sizes are now reported using standard metric prefixes (1 kB = 10^3 bytes = 1,000 bytes; 1 MB = 10^6 bytes = 1,000,000 bytes) rather than using binary-based prefixes (1 kB = 2^10 bytes = 1,024 bytes; 1 MB = 2^20 bytes = 1,048,576 bytes).
Lion's automount folders are no longer displayed in the network drive list.
OmniDiskSweeper has a new app icon!
The app is now signed with Developer ID so it works well with Gatekeeper on Mountain Lion.

Several behind-the-scenes updates to the built-in software update feature, and one very useful new feature: you can now tell software update to ignore a specific update.
Updated OmniDiskSweeper's crash catcher to be compatible with Snow Leopard.
New release notes no longer display on launch; they're still available from the software update feed, the download page, and the Help menu.

Updated licensing code with latest changes from OmniFocus: single-user licenses now support simultaneous use on both a desktop and a laptop, and some state change bugs (resulting in things like a stuck "Querying Network" status) are fixed.
Updated the punctuation in a few localized strings.

Finally found and worked around the help tag cell-copying bug which was causing crashes on 10.5.

When multiple files or folders are selected, choosing Update from the File menu will now update all of the selected items rather than just one of them.

Fixed some locking issues with the background thread that could sometimes lead to crashes.
Fixed a memory leak seen when closing a window while it's still in the process of updating sizes.
Reduced the memory footprint of each file being scanned.
When no files are selected, choosing Update from the File menu will now update the entire window.

The code used in OmniDiskSweeper is now signed for Leopard's benefit. (For more information, see Leopard's code signing release notes.)

Fixed a rare crash that could happen in drawing code while sizing or deleting files.
Fixed a bug where "Check for Updates" would sometimes hang when no updates were available. (Unfortunately, this change breaks the recently-integrated French localization of the software update window. We'll fix that again soon!)
When Software Update finds an update with the same major version as the currently licensed application (e.g. OmniDiskSweeper 1.x), it should now correctly indicate that its price is free.
The license window will no longer continue to display "No license available" after a license is added.
License files will no longer be created with the "execute" permission enabled. (The files were never actually executable.)

OmniDiskSweeper is now available in French, thanks to the efforts of Corentin Cras-Méneur and Joselyne Rochaud!
Setting the DebugPackageScanning default to true will log some diagnostic information to the Console when scanning package receipts.

Added this Message of the Day.
Hopefully worked around an issue on 10.5 Leopard which would sometimes cause our normally well-behaved "lsbom" child tasks to turn into zombie processes that would fill up the user's process table, leading to "No more processes" errors in other applications. (We weren't able to reproduce this here, so we can't prove that this fixes the issue. If you were seeing this, please let us know if this fix works!)
Rewrote the package scanner to find all the system packages on 10.5 Leopard.
If we can't find the factory-installed font "Helvetica-Oblique" (which we normally use for linked files), we now fall back on using the system font rather than crashing.
The built-in software update can now automatically download and install its updates.
