Version 1.51 has been released and is available for download.
It's mainly a maintenance release providing several fixes.

Version 1.51 is fully backward compatible with 1.50.
If a previous version of the package is already installed it is not necessary to uninstall it, simply overwrite it.

Details of changes:

- Problem #0021 June 12, 2007
 Bug in SDK InsAutopilotControlState() API
 Turning unit 'x' (1<=x<=3) ON does not automatically turn other
 active units OFF.

- Problem #0022 June 15, 2007
 Fix in SDK external BatParallel state management.

- Problem #0023 June 10, 2007
 The SDK diagnostic gauge distributed in the package is still the same
 distributed with version 1.40 and, since the SDK is not compatible, it
 does no longer work with gauges version 1.5x. Now supplied gauge has
 been recompiled to be compatible with current SDK version.

- Problem #0024 August 30, 2007
 Serious bug found in the Data Save and Restore functionality. When INS
 State Data is saved, the gauge also saves the dynamically allocated list
 of ADEU files. When such data is reloaded, ADEU gauge can cause FS to
 crash. Now the list is deallocated before saving/restoring data to disk,
 and then reallocated.

- Problem #0025 September 15, 2007
 Wrong management of PI value and simulated drfting.
 Inertial platform drifting should not occur until the aircraft is moved,
 even if INS is already in NAV Mode.

The only new thing is the CDU Mouse Wheel support which has
been added to:
 - CDU Data selector knob
 - CDU Dim control knob
 - CDU Waypoint/DME selector
 - ADEU filename selectors
 Now they can be operated both with the left mouse button, as before,
 and with the mouse wheel.
