Fixed Issues:

- Changing VT_BYREF Variants in managed code could lead to a memory leak.

- Inappropriate caching of current UI culture even after CultureInfo.ClearCachedData is called.

- For the HttpWebRequest method, an uncatchable ObjectDisposedException could occur when exiting an application with asynchronous requests.

- Visual Studio hangs on setting a Breakpoint in a function with an infinite loop when it is called from the Immediate Window.

- Breakpoints do not work if the cached, managed dlls in the bcl directory differ from the ones on the device.

- Environment.GetFolderPath returns an InvalidOperationException.

- An access violation occurs when accessing .theControls or .Controls.Count property of a control once it has begun the disposing process.

- The WebBrowser.DocumentCompleted event is fired in a loop when the DocumentText property contains an image inside of a table.

- Files should be extracted to the main storage as a workaround to avoid hardware issues on some storage cards.

- For the HttpWebRequest method, an ArgumentOutOfRangeException occurs when accessing some https:// URLs.

- Timer breaks after GetTickCount wraps around (49.7 days).

- Error occurs when loading the .NET Compact Framework version 2.0 on a device using an ActiveSync push.

- Memory leaks occur when using Com marshaling.

- Installer should check for ActiveSync version and disable deployment if version is older than ActiveSync 4.0 build 4343.

- For the SerialPort class, an IOException is thrown when opening a serial port on the IPAQ 4150.

- A call to HttpWebRequest over SSL with a payload greater than 32 KB hangs on the client when SendChunked returns false.

- For the SerialPort class,an uncatchable exception occurs when Bluetooth is turned off.

- A finalizer for the FileStream class will cause the application to crash if a previous IO operation failed.

- Installation of the .NET Compact Framework fails on low memory devices.

- PInvoke return types of UIntPtr throw a NotSupportedException.

- The Debug.WriteLine method in the .NET Compact framework version 2.0 is not working.

- For the SerialPort class, virtual serial ports are not reported by the SerialPort.GetPortNames method.

- When using COM Interop, a VARIANT_BOOL type is passed incorrectly on ARMV4I.

- The .NET Compact Framework incorrectly performs version comparison when loading assemblies.

- ARMV4I runtime should be removed from ARMV4 Pocket PC CAB to reduce the size of the CAB.

- Corrections needed for Http Abort semantics.

- The DateTime.Now method throws an ArgumentOutOfRangeException.

- Crash caused by using CurrentTimeZone.GetDaylightTime and CurrentTimeZone.GetStandardTime in certain rare stress conditions.

Strange, I still get "Out of memory" problems when installing on my SD Card

Wow an extra 5Mb of free storage. Thank you Uncle Bill and your little wizards.
