DataThis list makes no claim of completeness, accuracy, or anything else. Its available merely as an aid.

2.62

• Fix.GUI: Fixed broken baloon tips in previous couple versions.
• Fix.GUI: Fixed possible issues in default process affinity dialog box on boxes with more than 4 virtual processors.
• Fix.GUI: Fixed default CPU affinity change behavior on a process that doesn't already have a default CPU affinity set (it gets befuddled, but subsequent changes seemed correctly implemented).
• Fix.GUI: Fixed inability to rollup Process Lasso application window when using WindowBlinds.
• Fix.Core: Some minor logic fixes and optimizations.
• Fix.Core: Adjusted use of mutex object to log accesses to prevent any possible problems.
• Change.Core: Changed default OOC total CPU usage before restraint to 75% (from 95%).
• Addition.GUI: Added German translation provided by ixnay.
• Addition.GUI: Added Dutch translation provided by sanderg.
• Addition.GUI: Some facilitating localization code.
• Addition.GUI: Added current resource language module to about box info.
• Addition.GUI: Added 'encouraged development' button to about box.
• Addition.GUI: Added warning text notification over graph area when processgovernor.exe isn't running.
• Installer.Fix: Fixed wrong build of TweakScheduler.exe sometimes being included causing invocations of TweakScheduler to fail.
• Installer.Addition: Added updatechecker resource strings to optional localization section (for translators to use).
• Installer.Change. Added new start menu subfolder 'repair' and moved 'reset saved window positions' to it.
• Installer.Change: Added new 'reset language' start menu option to new repair group.
• Installer.Change: Changed add/remote programs display name to 'Process Lasso' instead of 'ProcessLasso'.
• Installer.Change: Some cleanup.
• LangPicker.Change: Double-click can select language from listview now. (will propogate to all Bitsum product thats use this module)
• Change.GUI: Changed title to 'Process Lasso'.

2.60

• Addition.GUI: By popular request, added retention of process listview settings (column ordering and widths).

2.58

• Addition.GUI: Added page fault delta (page faults per interval) column to process listview. This is an important metric so I figured it should be there. Note that represents the number of times a page of memory needs to be loaded into the process space (i.e. read from the page file), otherwise known as a page-in. Some page faults in the counter may be 'soft' faults though in that the page need not be loaded from the page file.
• Addition.GUI: Added ability to choose new configuration store folder.
• Addition.GUI: Added ability to export configuration file.
• Addition.GUI: Added ability to import configuration file.
• Fix.GUI.Perf: Fixed performance issues with the log file that could have caused brief spikes in CPU usage by processsupervisor.exe, especially as the log file grew in size. The log listview code is now much more optimal.
• Fix.GUI: Fixed listview not resorting when sorting by some dynamic columns (note that it still resorts only when necessary to conserve CPU cycles).
• Change.GUI.Perf: Rewrote log subsystem completely. Its now much more optimal.
• Change.GUI: Removed an old, now unused, toolbar bitmap from the resources, there-by decreasing executable size.
• Change.GUI: Added additional information to about box.
• Core.Change: Changed default config and log file location to user's application data directory store. This allows per-user configuration and the ability for 'limited' users to write to their personal configuration and the log file. NOTE: Automatic migration of your INI config and log files should occur for the current user installing the product. Other users may need to reinstall Process Lasso under their accounts to invoke the migration.
• Core.Change: If we don't have write access to the log file, default it back to the user application data directory, with the assumption of a limited user stuck with an old log file pathname into the program files directory.
• Installer.Change: General cleanup.
• Installer.Addition: Added revision history (HTML).
• Installer.Addition: Added new version migration section that copies INI and LOG files to new default locations.

2.56

• GUI.Fix: System tray icon can is now restored if explorer crashes/restarts.
• Updater.Change: Now defaults to not including beta versions in the update query.
• TestLasso.Change: Added timeout of 7.5 seconds in case of failure.

2.54

• Fix.GUI: Fixed 'only lower priority of normal priority processes' OOC option not persisting.
• Change.GUI: Optimized loading of config file (doesn't reload if file modification time hasn't changed). This may reduce unnecessary configuration file refreshes for events like opening menu items.

2.52

• Addition.GUI: Added 'match pathnames' option to disallowed processes. This allows for optional additional matching on the process pathname.
• Addition.GUI: Added hint about most active process to system tray tooltip.
• Addition.Core: Added new match pathnames code.
• Change.Core: Considerably optimized primary loop.
• Fix.Installer: Now properly rembers last install dir.

• Change.Installer: Removed GUI hotkey for now.

2.50

• Addition.GUI: Position of window and child windows is now saved at exit and restored at re-launch.
• Addition.GUI: Added 'View' menu item and 'Show Legend' option to toggle display of graph legend.
• Optimization.GUI: Reduced main window procedure CPU cycles per message.
• Change.GUI: Changed 'File' menu item back to 'Actions'.
• Fix.GUI: Removed some incidental debug output left in final builds (minor).
• Change.UpdateChecker: Cosmetic changes.
• Installer.Fix: Remembers last installed path during an upgrade/reinstall. [TESTING NEEDED]
• Installer.Fix: Added code to run gdiplus.exe or gdiplus-installer.exe, if present in the CWD, to install gdiplus.dll. This is opposed to downloading gdiplus.
• Installer.Addition: Added hotkey to invoke Process Lasso GUI (or show its window)- ALT|CTRL|SHIFT|F12. Can be edited, post-install, in properties of start menu shortcut. {EXPERIMENTAL, MAY UNDO THIS}
• Installer.Change: Moved advanced menu items to a new subfolder of process lasso's start menu folder.
• Installer.Change: Re-enabled advanced menu item section by default.
• Installer.Fix: Now forcibly terminates running copies of processsupervisor.exe and processgovernor.exe even if they are running in other user sessions to avoid 'in-use' errors when trying to update.
• Installer.Change: Made 'localization files' section disabled by default. Note this isn't actual translations, just the kit necessary to translate PL.


• Fix.Updater: Fix 'auto check' mode so it doesn't keep checking in an infinite loop when the update check dialog is opened.
• Fix.Updater: Fixed 'never check' setting - it wasn't getting saved/restored correctly.
• Fix.GUI.Updater: Fixed up updater invocation. Defaults to checking every three days. Turn 'automatically check' on and it'll just notify you if an update is available without bothering you with the dialog box otherwise.

2.48

• Change.GUI: No longer lists processes a user has no access to (i.e. a 'limited' user).

2.46

• Addition.GUI: Added 'Donate Now' button to free build.
• Change.GUI: Removed some unused bitmaps from the executable's resources.
• Installer.Change/Fix: Switched to inetc plug-in instead of nsisdl to hopefully resolve proxy server issues when downloading gdiplus.dll in cases when its necessary.

2.42

• Addition.Core: Added optional exclusion of non-normal priority processes from OOC restraint (defaults off).
• Addition.Core: Added optional exclusion of foreground processes from OOC restraint (defaults on).
• Addition.GUI: Added 'Do not lower priority of foreground process' to OOC (out-of-control) config dialog.
• Addition.GUI: Added 'Lower priority only of processes of normal priority' to OOC (out-of-control) config dialog.
• Change.GUI: Improved look of OOC config dialog slightly.
• Fix.TestLasso: Fixed for Vista (and elsewhere if there was a problem).
• Change.Defaults: Changed default OOC config to 2 seconds before restraint, from 1.5 seconds. This will reduce sensitivity just a bit. Remember, for upgrades defaults are not reset now; you must check the applicable section in the installer or use the GUI.
• Change.Defaults: Changed default show balloon tips back to off.

2.40

• Installer.Change: Changed so reset default config is optional.
• Fix.Core: Fixed applicaton of default CPU affinities even when unnecessary (affinity already set right).

2.38

• Fix.Core: Propogated previous Vista fix to the GUI to the core engine, which should save a few CPU cycles, though probably not noticable since consumption was so low to start with.
