Release 4.51 (Build 080623)

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 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.

Release 4.5 (Build 080312)

* Added support for new portable Mac systems with Intel T8000 processors.
* Added temperature sensor support for the standard PATA hard drive of the MacBook Air.
* Support for on-core temperature sensors of Intel processors based on 45 nm technology ("Penryn") has been modified: As confirmed by Intel, the core sensors behave no longer linear enough for the display of absolute readings in low temperature ranges. For this reason, support for core temperature sensors in 45 nm technology has been removed in Temperature Monitor.
* The application will now detect first generation Intel Core processors which are affected by a hardware problem that can cause the core temperature sensors to stop working after the system wakes from sleep mode.
* Corrected a problem with the display of Intel processor model codes when the model code was greater than 15.

Release 4.4 (Build 080211)

* Added support for new Macintosh systems equipped with Intel Xeon 5400 processors.
* Added support for the MacBook Air.
* 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.

Release 4.3 (Build 071024)

* Added official support for the iMac models published in August 2007.
* Removed support for Mac OS X 10.2 Jaguar and other operating systems releases prior to version 10.3.8.
* Added support for Mac OS X 10.5 Leopard.
* The status of the extreme value drawer, ruler mode, and the display of curve labels for history windows is now saved to preferences. Each history window will individually restore these settings when the application is relaunched.
* The markers for showing extreme values in history windows can now also be selected via keyboard while the history drawer is open.
* The panel for connecting to remotely monitored computers now uses better support for multi-homed systems.
* The application no longer locks its history features when it detects a corrupt file for storing long-term history values. In this case the damaged data will be ignored and be removed automatically.

• Added support for the new MacBook Pro series introduced in June 2007.
• Added support for a variety of internal temperature sensors of new hard drive models. This affects old Macintosh computers not supporting the AHCI standard.
• Alert panels now display the exact time when the alert situation was detected.
• Selected display preferences for the Dock icon can now be set directly via the context menu of the Dock icon.
• By user request, the Lite version has a new menu item to immediately refresh the display of readings independent of the regular update interval.
• By user request, the Lite version has now support for sensor alerts. The actions to display alert panels, to play the warning sound, and to run external applications are supported.
• The handling of repaired or refurbished Macintosh systems which don't have a valid serial number has been enhanced.
• Modified preference values are now committed to stable storage immediately when the preferences window is closed. This can reduce the likelihood that changes are lost when the application is used to diagnose problems on a computer with defective hardware.

This is a small maintenance update which only enhances minor issues in the user interface:

• The menu-bar display will now be highlighted when the menu is open.
• It is now possible to delete the full sensor preferences set of a remotely monitored computer by a single mouse click when that machine has been taken offline and is no longer connected to the local computer.
• Corrects a scaling issue affecting the display of history curves when a long term history display had been zoomed out and the window width resulted in a horizontal time sampling resolution between 1 and 2 minutes per pixel.
• The resize behavior of the remote connection window was optimized.
• Enhanced compatibility of the disk saver feature with Mac OS X Jaguar.
• The internal hard drive sensor of Maxtor MaXLine Pro 500 (7H500F0) drives is now also detected by PPC-based Macintosh systems.

• Added support for a large number of new temperature sensors of Intel-based Macintosh systems. This includes thermal diodes monitoring the processors externally, GPU sensors, drive bay sensors and FB-DIMM sensors of the Mac Pro, etc.
• Added new feature to combine multiple history windows, making it possible to put sensors with different quantities into direct relation with each other. The user can define overlays for any selection of graphs.
• Readings of sensors which have raised an alarm are now displayed with warning markers in the sensor window, the screen display, and the menu-bar.
• The display of sensor readings in some output channels has been optimized further. No additional space is added in front of the readings which consumes less screen real-estate and enhances the appearance in windows where left-aligned layouts were selected.
• Corrected a problem where the curves of history graphs could show a flicker effect under very special circumstances.

NOTE: Some specific sensor location labels for Intel-based systems are subject to change and may not be final. Compatibility Reports for the new Core 2-based Mac series created via the Help menu of Hardware Monitor are welcome. Intel Xserve models are not fully supported yet. Support will be added when these systems become available.

-Added support for the 4 new iMac series introduced in September 2006.

-Added support for temperature sensors in some old hard drives which are not fully compliant with today's implementation of the S.M.A.R.T. industry standard.

-If rulers are enabled for history windows, the application will now always try to keep the position of the crosshairs, no matter how the window or the selected time interval are resized.

-By user request, the old feature to display history curves in a scaled down fashion has been reinstated. Clicking on a new zoom button now allows to switch between a scaled down time axis, and display in full time resolution.

-Output of readings has been optimized to avoid leading blanks whenever possible. This produces better output, especially in the Dock and menu-bar channels, and in cases where the user has selected a combined Celsius/Fahrenheit display.

-The panel to display processor details will now better differentiate between logical processors, number of cores per processing unit, and physical number of processing units. It will also correctly reflect the number of currently deactivated processors.

-Corrected a problem where the marketing name of Xeon 5100 processors was not displayed in the processor detail panel.

-Corrected a problem where the application could raise a low sensor reading alert when the sensor was temporarily in a disconnected status.

• Added full support for the new Apple Xserve Quad Xeon.
• Added support for S.M.A.R.T. temperature sensors in SATA drives connected via an SAS bus.
• Added new "disk saver" preference which allows users to stop monitoring of internal hard drive sensors when the system is idle. Idle drives can now enter sleep mode and be held in sleep mode, independently of S.M.A.R.T. monitor time interval settings.
• The user interface for drawers in the history windows has been consolidated. There is now a single drawer for colors and extreme values.
• The color preferences for the visualization of sensors can now also be set via the color drawers of history windows.
• Added feature to add small labels to history curves. The labels use the sensors' short names configured in preferences.
• Added feature to automatically recover from situations where one sensor stopped responding and the application was about to be halted by the operating system. (These situations can typically occur in machines where hard drives need more than 12 seconds to wake up from sleep mode, or where third-party applications are blocking the ATA busses for extended periods of time.) When such a situation is detected, the application will automatically stop all its activities, allowing the operating system to resolve the problem. After a certain amount of time, the application will reactivate itself and resume operation.
• Access to sensors where the user preference "Don't acquire readings" was switched on is now prevented completely at the hardware level.
• Corrected a problem where the installation of the driver for extended x86 sensor support could fail if the application had been put in a folder which had a name with non-ASCII characters.
• Corrected a problem where a memory sensor in portable Core 2 Duo systems was misidentified as being a memory riser-card sensor.
• Corrected a problem where the internal temperature sensor of Hitachi Deskstar 7K500 drives was no longer seen as functioning sensor.
• Corrected a problem in the preference panel where some settings in the user interface were not updated correctly when the configuration tables for history windows and alerts were only controlled by keyboard, not by mouse.
