Lemke Software GmbH has updated its popular Mac graphics utility GraphicConverter to version 5.2.3. GraphicConverter imports about 175 graphics formats, exports about 75, provides basic editing features, manages batch processing and more. The new release makes the customary dozens of changes, additions and bug fixes frequent users expect to see out of every maintenance release, along with a completely redesigned Rename dialog and the ability to replace now added to Rename as well. A complete list of changes is available online. GraphicConverter 5.2.3 is a free upgrade for registered users of version 4.5 or higher (excluding users of the version bundled with some Macs), and the full version costs US$35 to register.
