Hazel 2.1 Release Notes

Leopard (OS X 10.5) compatibility.
Added “Make alias” action.
Added “Reveal in Finder” action.
Expanded support for different file “Kinds”. Using the “Other…” option, you can choose from a list of every file type on the system.
For certain attributes, you can match against whether it is blank or not.

Tweaked general layout of the folder pane.
Re-arranged items in the action pop-up. Also, removed prepositions from action names and moved them into their own label after the pop up. Should be more consistent now.
Re-arranged and added items to the pop-up of “Kind” values.
Re-arranged a couple items in the attribute pop up.
Fixed rule preview erroneously indicating that Hazel would descend into non-folders (aliases and symbolic links, for example).
Fixed sporadic crash when canceling out of the rule sheet.
Should now be able to find iTunes playlists/iPhoto albums in cases where the user moved the whole library by launching iTunes/iPhoto while holding down the option key.
The rule preview should handle the case of missing metadata better now.

Support for “Folder” and “Alias” Kinds even on filesystems where metadata is unavailable.
Improved performance when calculating the size of folders. Should hopefully address performance issues when using rules that filter on size and also descend into subfolders.
Changed how the Kind attribute prints out in filenames. Prints the actual Kind and not the more general categories that appear in the pop-up.
Fixed sizing calculations following symbolic links. Should no longer do that.
Fixed the hours attribute, when set to 24 hour clock, printing out values between 1-24 instead of 0-23.
Fixed Spotlight attributes that are lists (like the Authors field) printing out with parentheses or extra quotes when used in file renaming or subfolder creation.
You can now edit the casing (lowercase, uppercase, etc.) of Spotlight file attributes that are lists (like the “Authors” field). Just click on the token for the different options.
Fixed cases of file attributes with colons being used in filenames.
Fixed asterisks being used in conditions making the rules uneditable later.
Fixed case when having multiple App Sweep panels, the second one would become unresponsive after throwing away files in the first one.
