Added experimental support for the Nuvoton NCT6791D super I/O chip.

Updated the version.

Improved the code used to draw a line between the different OxyPlot subplots.

Changed the name of RAM hardware to be always "Generic Memory" because the information from the SMBIOS table is not reliable.

Added the NCT6771F and NCT6776F chips to the lm-sensors interface.

Added code to handle exceptions when creating the report for drives that are no longer available/ready.

Changed the HDD detection to list hard drives without SMART support as well (at least if they have any visible partitions on them).

Added additional exception handling to the http server.

Fixed an issue in the ram group implementation (sensor values did not get stored to the settings instance).

Added Fahrenheit support to the plot.

Changed OxyPlot to draw a line between the different subplots.

Small correction to the plot with multiple axes.

Added an option to disable stacked axes in the plot.

Added experimental support for Intel Haswell CPUs.

Added the new OxyPlot based plot implementation.

Added binaries for the OxyPlot library and updated the License.html file.

Some modifications to the OxyPlot library to simplify the use in the Open Hardware Monitor.

Some modifications to the OxyPlot library to back-port to .NET 2.0. Added the LINQBridge library for the LINQ based code in OxyPlot (the original .NET LINQ is not available in .NET 2.0).

Added the source code of OxyPlot as of commit d190d7748a73 (6.5.2013).

Changed the super I/O fan control: Fan controls are now always displayed, even if the value is null (as for example for ITE 87XX chips in automatic mode.

Added additional Fintek chips to the lm-sensors interface.

Fixed Issue 368. Fixed Issue 369. Fixed Issue 370.

Changed the source formatting of the HttpServer class to match the rest of the project.

Reduced the amount of dynamic memory allocation when reading from the T-Balancer or creating tray icons.

Enabled fan control on mainboards by default.

Added support for fan control on ITE 87XX chips and a mainboard specific configuration for the Gigabyte GA 970A UD3 (both based on a patch from Eric Hokanson).

Changed a few types to internal (instead of public) in the Open Hardware Monitor library.

Fixed Issue 387. The new implementation does not try to start a ring 0 driver that already exists, but could not be opened. It tries to delete the driver and install it new. The driver is now stored temporarily in the application folder. The driver is not correctly removed on system shutdown.

Added a few checks and delays to the driver loading code to increase the chance of loading the driver.

Changed a few context menu items to display a radio option style. Added additional information from the SMBIOS to the report.

Added a RAM sensor for used memory.

Fixed an error where loading config files from previous versions would crash the application.

Updated the version.

Added temperature offset parameters to all HDD temperature sensors. Fixed issue 271.

Added a wrapper for the NotifyIconAdv to use the normal NotifyIcon class on Linux systems and the (fixed) custom implementation on Windows systems.

Added a RAM hardware and sensor, fixed Issue 115.

Added used space load sensors for hard drives.

Added a missing default case in the mainboard specific configuration selection. The missing default case prevented sensor data from getting displayed on unknown Asus mainboards with NCT6779D super I/O.

Added more report output to the kernel driver loading code. Hopefully this helps to find the problems in Issue 253.

Changed the system tray icon font scaling to adapt to the size of the tray icon in pixels, because on Windows 7 the tray icon scales with the system font size, while on Windows XP the tray icons are always 16 pixels large.

Improved the data compression for storing the recorded sensor values in the config file.

Attempt at fixing Issue 253 without breaking Issue 159 once more.

Fixed Issue 274. Fixed Issue 107.

Added the remote web enhancement developed by Prince Samuel.

Added the source code of the WinRing0 device driver.

Added the small modifications to the Aga.Controls required by the Open Hardware Monitor.

Added the source code of Aga.Controls (TreeViewAdv for .Net) version 1.7.0.0.

Changed the license to the Mozilla Public License 2.0 and update the licensing information.

Fixed a division by zero in the Sandforce write amplification sensor.

Added a simple way to customize the sensor gadget background. If any of the files gadget_background.png, gadget_image.png, gadget_foreground.png, gadget_bar_background.png or gadget_bar_foreground.png is present in the working directory then these files are used instead of the built in files.

Added experimental support for ITE IT8771E super I/O chips.

Added a new sensor type "Factor" for dimensionless values (and similar) that are not to be shown as percent ("Level" type). Changed the write amplification sensor to use the new "Factor" sensor type. Added the temperature SMART attribute for Sandforce SSDs as hidden sensor (as it may show fake results on some hardware).

Added additional smart attribute identification and a write amplification sensor for Sandforce based SSDs.

Small correction to the Sandforce SSD detection to prevent Marvell controllers (M4, C300) from getting identified as Sandforce.

Added a mainboard specific configuration for the ASUS P8Z68-V PRO.

Added a mainboard specific configuration for the ASUS P6T.

Added a mainboard specific configuration for the ASUS P9X79 (detailed fan and control configuration still missing).

Updated year to 2012 in properties and about box.

Further restricted the identification for Indilinx SSDs to prevent Maxtor HDDs to be identified as Indilinx SSD.

Small corrections for AMD family 15h CPUs (based on documentation).

Added SMART support for Samsung SSDs.

Added code to save and restore the plot sensor selection.

Added a context menu to the plot which allows the user to configure the time window for plotting.

Added the hard drive firmware version to the report. This could be important if the SMART attribute layout changes with firmware versions on some drives.

Modified and extended version of the patch v4 by Roland Reinl (see Issue 256). Main differences to the original patch: DeviceIoControl refactorings removed, SmartAttribute is now descriptive only and does not hold any state, report is written as one 80 columns table, sensors are created only for meaningful values and without duplicates (remaining life, temperatures, host writes and reads). Also the current implementation should really preserve all the functionality of the old system. Additionally there is now a simple SMART devices emulation class (DebugSmart) that can be used in place of WindowsSmart for testing with reported data.

Added first experimental support for fan control on the NCT677X super I/O chips.

Added additional Intel Sandy Bridge CPU power sensors.

Added Added a mainboard specific configuration for the Shuttle SH67Hx barebones. Added the SMBIOS system information to the report.

Added initial support for the ITE IT8772E super I/O chip.

Fixed the power sensor display in the desktop gadget.

Added support for Intel CPU power sensors (package and cores).

Buffered the gadget background drawing in order to improve drawing performance.

Fixed the Intel CPU package temperature sensor MSR.

Replaced the more expensive calls to DateTime.Now with DateTime.UtcNow.

Improved the CPU load sensors. The values displayed for the load per core and the total load should now be more accurate.

Added a mainboard specific configuration for the ASUS P8P67 mainboard.

Added a mainboard specific configuration for the ASUS P8P67 EVO mainboard.

Improved the mainboard specific configuration for the ASUS P8P67 PRO mainboard.

Added fan control for Nvidia GPUs based on a patch by Christian Valli?res.

Small correction for the mainboard specific configuration of the Gigabyte Z68X-UD7-B3 mainboard.

Added support for package level temperature sensors on new Intel Sandy Bridge CPUs.

Added a mainboard specific configuration for the Gigabyte Z68X-UD7-B3 mainboard.

Changed the maximum buffer size for double buffering of controls that isn't disposed after each draw call to the size of the screen. This should reduce the memory allocation and disposing on each sensor update. Also page faults are no longer increasing with this change.

Add a text (Open Hardware Monitor) to the main system tray icon to simplify identification.

Removed the bitmap.GetHbitmap call for every redraw of the gadget. This should reduce dynamic memory allocation and freeing and removes some of the page faults increasing.

Added initial support for AMD family 12h and 15h CPUs.

Added support for saving and restoring the sensor history for the last 24h. The sensor history is now saved in a reduced format (duplicate values are removed, gaps are marked with a NAN sensor value.

Fixed a problem preventing the plot form getting closed correctly. This did prevent the application from terminating when asked to exit by the operating system (for example at shutdown).

Added support for the Fintek F71889AD super I/O chip. Extended the identification list of mainboard manufacturers.

Added an option to show the plot in a separate window or on the right of the tree-view.

Added a mainboard specific configuration for the Gigabyte H67A-UD3H-B3 mainboard and fixed a few issues in the about box.

Improved the selection dragging on the tree view. The selection moves now only when the dragging starts on the tree view. With the old implementation, double-clicking the gadget would change the selection, because the mouse is still pressed when the main window is shown.

Added some GUI improvements: Better handling of the row selection, minimal row spacing of 18 pixel (to get nice dotted lines) and 3 decimal digits for voltages. Also changed the tree view font rendering to get better quality without ClearType.

Fixed the ATI GPU fan control. The settings now restore correctly to default settings (previously the "manual mode" was kept on some systems).

Fixed the bus and core clock reading on AMD family 10h model Ah CPUs. The new "Core Performance Boost" feature of these CPUs resulted in very low accuracy of the bus speed (and as a consequence also an inaccurate TSC multiplier). This fixed Issue 205.

Added a mainboard specific configuration for the Gigabyte P67A-UD4-B3 mainboard.

Added first experimental support for the IT8728F super I/O chip.

Added a mainboard specific configuration for the ASUS P8P67-M Pro and fixed a few problems in the NCT677X implementation.

Updated version info.

A first correction for reading core and bus clocks on AMD family 14h CPUs.

A small correction for AMD K8 (family 0Fh) core temperature reading, and fan reading on older revision of IT8712F chips. This should fix Issue 42 and Issue 194.

Added initial support for AMD Fusion (family 14h) CPUs.

Fixed a few details for the Linux GUI.

Replaced the StreamReader based lm-sensors access with an implementation using the FileStream class in order to avoid buffering problems when seeking.

Fixed the tree view row height on Linux.

Added support for AMD 10h core temperature sensors and Asus ATK0110 devices on Linux.

Added code to delete any kernel driver service that can't be opened before reinstalling it.

Added some error reporting to the Ring0 driver loading code.

Fixed some dpi scaling bugs that occurred when changing "Control Panel\Appearance and Personalization\Display" to 125% text size or 150% text size.

Added support for AMD family 11h CPUs.

Fixed the Intel Sandy Bridge CPU core clock calculation.

Added initial support for Intel Sandy Bridge CPUs.

Improved the saving and restoring of default fan control settings for ATI GPUs.

Added a minimal control interface to allow manual fan control and implemented the interface for ATI GPUs.

Fixed the temperature reading and improved the report for the Nuvoton NCT6771F super I/O chip.

Added first experimental support for the Nuvoton NCT6771F super I/O chip.

Improved the moving and resizing of the gadget on multi-monitor systems. Fixed one problem where the underlying gadget window size would be reduced unrequested. Fine tuned the progress bar size in the gadget.

Fixed a problem, where the MainForm location and size was lost when the application is started minimized and exited without ever showing the form. This caused MainForm_Load to be never called (location and size was not loaded), but the default size and location were still saved. The new implementation only saves the location and size when one of the two is changed.

Added code to catch the "System.Exception: This schema for this assembly has not been registered with WMI." when the user has now administrator rights.

Replaced the direct reference to the Mono.Posix assembly with reflection.

Added CPUID support for Linux.

Restricted the access to the kernel driver to system and built-in administrators.

Replaced the non-kernel code of WinRing0 with a managed implementation. The new implementation should fix Issue 32 and simplify further work on Issue 46.

Fixed the NullReference Exception

Added a Parent property to the WMI exposed Hardware objects

Updated attribute maps for the 4 SSD controllers we figured out so far.
Also switched back to an array of DriveAttribute rather than a generic list.

Removed the WMI Provider menu entry and restricted WMI to the Windows platform.

Changed the SMART AttributeID type from an enum to a struct.

Renamed folder from Wmi to WMI also in the project file.

Renamed folder Wmi to WMI.

Added code to read the additional fans on the ASRock P55 Deluxe mainboard via special GPIO switching.

Small bits of refactoring.

AnkhSVN fails, TortoiseSVN to the rescue..

Added license to the WMI stuff and refactored a few things a little.

Added a WMI provider, documentation to follow.

Improved the invariant TSC frequency estimation code to ignore readings with a large error.

Added a mainboard specific configuration for the ASRock P55 Deluxe.

Added a mainboard specific configuration for the ASRock AOD790GX-128M

Reading the timeStampCounterMultiplier right at the beginning when the time stamp counter is estimated instead of reading it at each update. Refactored the IntelCPU code a bit.

Added initial SSD support for Intel, Indilinx, SandForce and Samsung drives. Experimental feature for now!

Added a new sensor type "Level" for wear or charge level (or any other percentage based sensors that don't fit into Load or Control).

Added more error checking to the T-Balancer enumeration code. This hopefully fixes an IndexOutOfRangeException in the TBalancerGroup constructor.

Changed the way window position is saved and handled. This should now work properly.

Cleaned the macros up a bit.

Fixed the context menu positioning as well, following the previous fix to multimonitor setups.

Fixed an issue where the gadget would not be movable on an extra monitor positioned to the left of the primary monitor.

Removed unused assemblies.

Replaced HttpUtility.UrlEncode with Uri.EscapeDataString and deleted the reference to the System.Web assembly. The System.Web assembly seems to be missing on some .NET 4.0 installations (and the overhead of using it is a bit large, just for the UrlEncode method).

Reverted the SMART temperature attribute search strategy to the one used previously. Fixed a few minor details in the HDDGroup class.

Added a S.M.A.R.T dump for all drives, regardless of temperature presence so that we can start debugging SSD's and such.

Fixed the initialization of the TSC estimating code.

Fixed some problems when compiling in Mono and running on Linux.

Improved the implementation for the AMD 10h family CPU clock speeds.

Fixed a problem where the ADL Main_Memory_Alloc callback delegate could be garbage collected while still in use.

Added support for more than one Heatmaster fan controller.

Added an option to minimize on close.

A first (experimental) implementation for the AMD 10h family CPU clock speeds.

Rewritten the PCI access for AMD CPUs.

Refactored some of the hardware monitoring code and fixed a few code inspection warnings.

Fixed some silly mistakes

Added thermal and voltage/frequency MSRs for K8 CPUs, fixed chars-per-line limit

Added core and bus clock readings for AMD's K8 (0F) family of CPUs

Refactored the CPU classes and added a GenericCPU class.

Changed the trimming in the treeView to StringTrimming.EllipsisCharacter.

Corrected the size of the DriveCommandParameter structure to match the documentation of SENDCMDINPARAMS http://msdn.microsoft.com/en-us/library/ff565401%28VS.85%29.aspx
