• Bug fix for "automatically add to PDB search path". Paths are reset to match the file settings dialog/wizard prior to launching/injecting/waiting on an application. Paths are then rediscovered. This means that for situations where you have multiple versions of the same DLL in your development environment, the correct paths to your PDBs are used, rather than paths to PDBs in potentially other directories on your system than the particular DLL in use at the time.
• Bug fix for SAFEARRAYs of BSTRs, these were not correctly accounted for when the SAFEARRAY was passed to ::VariantClear(). This resulted in BSTRs incorrectly being marked as leaked when they were not leaked. Typically this manifests when using COleSafeArray to hold BSTRs.
• New hook for SafeArrayGetElement(), so that BSTRs returned from a SAFEARRAY are tracked.
• Default for hooking delay loaded functions is now TRUE.
• Default for hooking delay loaded DLLs is now TRUE.

Memory Validator has a high speed memory allocator that is used for managing interprocess communications work packages. If an allocation request for more than 128KB is made under specific conditions a crash may occur when using the memory allocated. This has been fixed.
• The launch wizard for Novice and Intermediate modes sometimes would not enable the Next >> button. This has been fixed.

Version 2.11
Version 2.11 includes the following new functionality:

• Add support for PDB files in any directory.
• Bug fix for a very rare crash during program shutdown after MSVCRT.DLL has unloaded. Most customers will not have seen this bug.
• Bug fix for a incorrectly truncated DLL name sent from stub to user interface. This bug resulted in corrupt DLL names being displayed in the dll hook status dialog.
