This is a maintenance update which reacts to recent developments in Mac OS X Leopard and fixes minor problems.

- Added a feature to detect a common damage of Leopard installations where users have intentionally destroyed the system's speech synthesizer to save storage space.
- The readings of non-working GPU-load sensors provided by some of Apple's graphics drivers for Leopard are now correctly suppressed by the application. Instead of displaying a constant zero value, the sensor will be removed entirely.
- Support for monitoring the frequency of Intel processors based on 45 nm technology ("Penryn") has been withdrawn. The sensor might not reflect the true performance mode under all operating conditions.
- The mechanism to detect ambiguities in machine production dates has been optimized. Computers built in 2008 are now always displayed with their correct dates of production.

- Added support for new Macintosh systems equipped with Intel Xeon 5400 processors.
- Added support for the MacBook Air.
- Added full support for load sensors of Intel GMA X 3100 and ATI Radeon X 2000 graphics chips (Hardware Monitor only).
- Added new feature for drives equipped with activity LEDs. To help users in identifying drives, it is now possible to let drives light up their activity indicators via the Drive Overview window.
- It is now possible to directly connect to remote computers by double-clicking entries in the connect panel.
- Sensor labels can now be reset to their initial default designations.
- The FAQ chapter in the reference manual has been revised.
- Many small optimizations in user guidance.
