You can choose to use the original symbol collection method, the new method, and to use caching or not.
    • New "IIS Tools" menu, which is enabled on NT Server systems. This menu provides useful helper actions for controlling IIS, SMTP, NNTP, FTP services when working with IIS. This means a software developer will not need to keep using the command prompt to type "net start ...." etc.

    Version 3.02 includes the following new functionality:

    • Bug fix for Pages tab when displaying from an archived session.

    • New Show GDI Objects... option on context menu for Memory tab. This option allows you to view the GDI object in your application. This is a customer requested feature.
    • New implementation for Uninitialised data hooking. New implementation creates less FALSE positives, and also hooks more constructors and destructors.
    • Addition of "COM Objects..." query on the Analysis tab.
    • Improved settings dialog.
    • Removal of superfluous user interface controls for COM and uninitalised data hooking.
    • Removal of speculative leak detect feature. The feature works correctly, but is unrealistically slow with large datasets, rendering the feature unusable. A modified form of this feature will be reintroduced when we have identified how to improve the speed of this feature.
    • Resource fix for message dialog for in-place-leak detect dialog.

    Version 2.96
    Version 2.96 includes the following new functionality:

    • Bug fix for COM Reference hooking. New implementation using DbgHelp.dll rather than relying on class vtable structure. New implementation is more robust and has the added bonus that you only track interfaces/classes for which you have debug information, which means you don't track interfaces/classes that you don't control.

    Version 2.95 includes the following new functionality:

    • Minor improvement to global hook interceptor.

    Version 2.94
    Version 2.94 includes the following new functionality:

This feature was added after we spent 2 weeks looking for a problem in Memory Validator, only to find the root of the problem was a 3rd party global hook.

      Memory Validator will now detect global hooks trying to load and ask the user for permission to load the global hook.

    • Various minor bug fixes.

    • Improvements to function hooking algorithms for Memory Corruption Detection, Uninitialised data, COM Reference counting.
    • Potential deadlock during advanced hooking algorithms, prevented.
    • Improved detection of functions in code sections. Previous algorithm had the potential to incorrectly identify data in code blocks as code. New algorithm use new PDB API to correctly identify functions.
    • Bug fix for broken handle leak detection for MSVCRT(D).DLL.

    Version 2.81
    Version 2.81 includes the following new functionality:

    • We have reorganised how certain allocations are handled so that the heaps underlying CRT allocations and the virtual allocations underlying heap allocations cannot interact with each other. The previous design should have prevented any interaction, we have no knowledge of any adverse interaction with the previous design. The new design improves performance and guarantees no interaction between the allocation tracking for different allocators.
    • Data processing for HeapAlloc() family of allocators modified to improve performance and prevent potential address collision with addresses from VirtualAlloc().
    • Data processing for User Defined family of allocators modified to improve performance and prevent potential address collision with addresses from VirtualAlloc().

    Version 2.77
    Version 2.77 includes the following new functionality:

    • Bug fix for off-by-one error on Objects tab. Symptoms of this are random crashes or Memory Validator simply disappearing with no warning whilst updating the display on the objects tab. This appear to be quite a rare to see and is data specific.
    • Performance improvement for processing SysAllocHook, BSTR and Variant family of allocations.

    • 2 Bug fixes for shutdown code for console apps.
    • Improved map file handling.
    • Improved symbol handling for MFC DLLs - some users were not getting symbols for MFC DLLs. This was dependent on many factors including the O.S. and dll version. MFC symbols are now always sourced from the application under test, resulting in accurate symbols all the time.
    • For the case where MFC DLLs generate OrdinalNNN symbols, these symbols are automatically mapped via the .def files installed with Dev Studio, to generate symbol names even when the PDB files cannot supply them.
    • Various internal bug fixes

    Version 2.72
    Version 2.72 includes the following new functionality:

    • Implementation change for SafeArrayGetElement() hook .

    Version 2.66 includes the following new functionality:

    • Bug fix for move filter dialog when no session.

    Version 2.65
    Version 2.65 includes the following new functionality:

    • Bug fix for the global hook rejection filter on LoadLibrary(Ex). For the cases where the filter prevented the loading of a DLL, it was possible for some registers to be corrupted, resulting in unpredictable application behaviour.
    • Bug fix for hooking CRT operator delete [].

    Version 2.64
    Version 2.64 includes the following new functionality:

    • Bug fix for SAFEARRAYs inside VARIANTs. Prior to this bug fix, a SAFEARRAY inside a variant (COleSafeArray) may have shown up (incorrectly) as a memory leak.
    • Bug fix for PDB error message handling.

    Version 2.63
    Version 2.63 includes the following new functionality:

    • Speed up for virtual tree control deleting rows.
    • Extra error reporting relating to symbol tracking on diagnostic tab.
    • Internal minor bug fixes.
    • 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.
    • New messages on diagnostic tab when delay loaded functions are not hooked due to user settings.

    Version 2.60 includes the following new functionality:

    • Bug fix for calling GetFileVersionInfoSizeW() on Windows 2K and Windows XP. Windows NT systems do not suffer from this bug. Symptoms of the bug are applications failing to start properly (long pause then disappear or crash) on Windows 2000 and Windows XP.

    Version 2.59
    Version 2.59 includes the following new functionality:

    • Addition of various CRT hooks for the global namespace. In MFC applications these functions would not normally be called, as the MFC equivalent would be called. For applications not using MFC, memory allocated via these functions would not be tracked. Version 2.59 fixes this.
      • Visual C++ 4.2: global namespace ::operator new(unsigned int size, int blockType, char const *filename, int line); (debug only)
      • Visual C++ 6.0: global namespace ::operator new(unsigned int size, int blockType, char const *filename, int line); (debug only)
