New features:

3 new image formats: You can store snaphots as GIF, Photoshop file and TIFF (beside JPEG, PDF and PNG).
3 new text formats: You can store web pages as original HTML, resoloved HTML and as human readable text file.
A snapshot can directly be copied to the clipboard, to use it in other programs without storing it first.
The new parameters "Minimum Width", "Fixed Width" and "Maximum Height" are giving more control to the snap process.
The Browser menu now supports Firefox (beside Safari). You can directly access the actual page, the history and the bookmarks of the browsers.
SnapWeb now writes the URL of the web page into the comment field of the snapshot. This is very useful for archiving and searching snapshots in the Finder.
You can use SnapWeb as a tool from your Unix shell. (Professional license needed!)
12 new AppleScript commands. All SnapWeb features are now scriptable! (Professional license needed!)
A new command to clear the SnapWeb history on demand.
A new Help menu to directly access the manual and the BTS web site.

Improvements:

The natural web page size is now calculated much more exact (e.g. web pages with frame sets).
SnapWeb is now faster when you snap more than one file format at once.
Safari isn't starting anymore if you choose "Safari Actual Page" by mistake, without having it open.
SnapWeb prompts the user when no output format is selected.
SnapWeb has now a time-out value of 4 minutes, if very big web pages are overwhelming slow computers.
The "mouse flickering" during a snapshot is reduced.

Fixed bugs:

SnapWeb can now load https-URLs, which are directly typed into the URL field of the browser window.
During a snapshot SnapWeb was activating the left top active screen corner by mistake. Now it temporarily disables the active screen corner during runtime.
The Browser menu was crashing SnapWeb when the Preferences window was open.
SnapWeb sometimes crashed when you snapped more than one file format at once in evaluation mode.
Fixed a bug which occured on slower Macs (timeout during process).
SnapWeb crashed when the natural height of a web page was greater than 22767 pixels. Now SnapWeb supports heights of 32767. Taller web pages are truncated.
