Hex Fiend 2.1 is here. Hex Fiend is a fast and clever open source hex editor for Mac OS X.

Notable new features include:

• A binary diff viewer
• Support for reading raw devices (after authentication, natch)
• Selectable string encoding for the text view
• Bookmarks
• Transient untitled documents (aka "reuse that empty Untitled window")
• Undo preserved across saves, if it can be done efficiently
• Fresh new paint

Hex Fiend is now hosted on GitHub, which should make contributing patches easier for everyone.
