Version 0.18
Version 0.18 includes the following new functionality:

Addition code for pvLicense.exe and Performance Validator to cope with Windows File Protection preventing the upgrade of DBGHELP.DLL to a more recent version than the default installed for Windows 2000.

Version 0.17
Version 0.17 includes the following new functionality:

Addition of reset statistics button on toolbar (and menu). This buttons resets all times and visit counts to zero. Added due to beta test feedback.
Potential deadlock during 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.

Version 0.16
Version 0.16 includes the following new functionality:

Version V0.15 included an overzealous check for function jmps which prevented many functions from being hooked. V0.16 fixes this check.
Improved disassembly of functions.
Improved reporting of functions with no code, just return instructions.

Version 0.15
Version 0.15 includes the following new functionality:

Improved Line Timing display - shortest time of not visited lines now displayed as zero.
Improved Line Timing - line times now assigned to correct line (previously line was assigned the time for the previously executed line - which could be very misleading).
Class and Function filter for line timing now works correctly. You can now provide line timings on a per function, per class method or per class basis.
Hooked Source Files tab on setting dialog allows you to specify source files that should not be hooked or that should be hooked, allowing you to exclude parts of your application or to concentrate on parts of your application. This allows you to provide function and line timing on a per file basis. Be aware that if the class and function filter is setup at the same time you may end up filtering out all files/functions and no data will be collected at all - it is up to you to choose the appropriate settings for your application.
Misc deadlock avoidance improvements.
Display of data limited by threshold on Hotspots tab improved.
Improved editing of columns on all displays.

Version 0.14
Version 0.14 includes the following new functionality:

Bug fix for function re-writing hooks.
Bug fix for function hooking and line hooking. Both options can be enabled simultaneously without crashing the target application.

Version 0.13
Version 0.13 includes the following new functionality:

More Robustness improvement for function and line hooking.

Version 0.12
Version 0.12 includes the following new functionality:

Robustness improvement for function and line hooking.

Version 0.11

Version 0.11 has the following improvements and changes.

New Relations tab, displaying time consuming (or most visited) functions, their child functions and their parent functions.
New Line Timing tab, displaying times for individual lines.
New settings tabs to control line timing hooks.
New dialogs for launch, inject, wait (for both wizard and dialog modes)

Version 0.10

Version 0.10 has the following improvements and changes.

wWinMainCRTStartup or equivalent is now correctly hooked when attaching via CreateProcess(). This results in the majority of hotspots beign grouped under the main worker thread. All other hotspots are grouped per thread. DLL loads appear as separate hotspots at present.
Cursor right, cursor left and return key can now be used to expand, collapse and toggle the expand state on the hotspots and analysis tree controls.

Version 0.09

Version 0.09 has the following improvements and changes.

Statistics tab renamed Raw Statistics.
New Statistics tab that displays collated statistics from the raw statistics.
Changed default colours for hotspot graphs to improve readability.
New column, Class::Method.
Can sort columns by clicking on column headers.
Columns can be autosized by clicking close to the right hand edge of the column.
Column widths are stored between session.

Version 0.08

Version 0.08 has the following improvements and changes.

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 multiple hooking methods with the same name in different DLLs ("operator new" is an example).
The hooking method for all functions for performance monitoring has been improved, and now handles exceptions correctly.

Version 0.07
Version 0.07 includes the following new functionality:

Extra error reporting relating to symbol tracking on diagnostic tab.
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.
Internal minor bug fixes.

Version 0.06

Version 0.06 has the following improvements and changes.

Robustness improvement for boundary condition on memory mapped file.

Version 0.05

Version 0.05 has the following improvements and changes.

Performance improvement for virtual scrolled tree when deleting all rows.
C++ names now demangled.
Directory of files found using file open dialog are added to the source code locations searched for source files.
Crash profiling apps when exceed the number of performance graph nodes fixed.

Version 0.04

Version 0.04 has the following improvements and changes.

Fixed editing component bug.
Misc. internal improvements.

Version 0.03

Version 0.03 has the following improvements and changes.

Fixed function hooker bug which meant that for some apps/modules no functions would be hooked.
Fixed structured exception handling bug which meant that if your application threw an exception, the profiling hooks would prevent the exception from being handled correctly.
Fixed various statistics display bugs.

Version 0.02

Version 0.02 has the following improvements and changes.

Improved handling of version.dll.
Internal bug fixes for tracking data.

Version 0.01

Initial beta version of Performance Validator made available to selected beta testers. We would like your feedback on any bugs you may find, on the features and benefits of the software, and also feedback on features that you think are missing from the software but which you would find useful.

NT Service support is still under development. You can link to the NT Services Performance Validator support DLLs but don't expect Performance information to be displayed for services.
