Releases

2.9.3

July 8, 2025

All platforms

• Breaking change: "-fstandalone-debug" is no longer a required compiler option, since it can significantly increase debug information size.

  Instead, Live++ internally takes care of it.

  Thank you to Simon Coenen from Guerrilla Games for reporting this.

• Fixed a bug where the Broker would crash when unregistering an incomplete module that was loaded from different paths into different processes.

  Thanks to Tristan Bell and Neil Stewart from Electronic Arts for bringing this to our attention.

• Greatly reduced contention when loading several modules in parallel.

  This vastly improves Broker loading times for applications that load hundreds of dynamic libraries, such as modular Unreal Engine builds.

  Thank you to Henrik Karlsson from Epic Games for reporting this and helping with performance improvements.

Windows, Xbox One® and Xbox Series X|S®

• Fixed a potentially endless loop in case the PDB path stored in the linker environment points to a path which is no longer available.

  Thanks to Tudor Fratean from Remedy Entertainment for bringing this to our attention.

• Fixed a bug where symbols from PCHs being pulled in would not be reconstructed before attempting to strip existing symbols.

  Thank you to Davi Farhi from Asobo Studio for reporting this.

• Fixed a bug where a non-matching candidate symbol would not be ignored correctly during symbol reconstruction, leading to ambiguities, causing existing symbols to not be recognized.

PlayStation®4 and PlayStation®5

• Implemented support for R_X86_64_GOTPCREL relocations in case they are explicitly requested from the assembler through -Wa,-mrelax-relocations=no.
• Implemented support for symbols that are named differently depending on optimization settings, which would break Hot-Deoptimize.
• .lwd files are now considered first before attempting to reconstruct the linker working directory from ELF paths.
• Updated documentation regarding .lwd file.
• Updated documentation regarding .d files.
• Updated documentation with optional linker options that need to be set.
• Improved robustness of producer string parsing.

  Thanks to Resmi Hasankolli from Electronic Arts for reporting this and helping with debugging this.

• Implemented handling of -MF option which must be removed for having .d files in the proper place for patches.
• Fixed identification of PCH compilands for unity splitting.
• Fixed a bug when parsing the compiland producer string for filenames with an uppercase extension.

  Thank you to Jean Farines from Asobo Studio for reporting this.

• Fixed a bug where some --redacted-- load events would be missed because the debug event handler wasn't created in time.

PlayStation®4

• Breaking API change: Implemented workaround for --redacted-- bug in the SDK.

  This requires users to call a new Live++ Agent API, see the documentation for details.

• The Live++ Agent is now fixed to build against SDK 12.000, which is a minimum requirement.

  Otherwise the Agent cannot be loaded on SDKs older than the one the Agent was built against.

PlayStation®5

• Breaking API change: Implemented workaround for --redacted-- bug in the SDK.

  This requires users to call a new Live++ Agent API, see the documentation for details.

• The Live++ Agent is now fixed to build against SDK 9.000, which is a minimum requirement.

  Otherwise the Agent cannot be loaded on SDKs older than the one the Agent was built against.

• Updated documentation with notice regarding SDK version checks.

2.9.2

June 2, 2025

Windows

• Added safety net against corrupted IPI build info records in the PDB.
• When a source file cannot be found when deoptimizing a file, do not attempt to recompile it on future hot-reloads, unless its state is changed again.
• Fixed a bug where the Agent would abandon its receiver thread, but the Broker would not realize that the connection had broken down, possibly waiting for a message to arrive indefinitely.
• Fixed a bug where the toast notification would not always show the correct icon based on status.
• Fixed _IMAGE_DOS_HEADER typedef to exactly match the definition in the Windows headers.

  Thanks to Resmi Hasankolli from Electronic Arts for reporting this.

PlayStation®4 and PlayStation®5

• Breaking change: "-fstandalone-debug" and "-Xclang -mno-constructor-aliases" are now required compiler options.
• Fixed a bug when using PCH paths that contain spaces, which would make the compiler choke on the resulting "-include-pch" with a quoted filename.

  Thank you to Jean Farines from Asobo Studio for reporting this.

• Fixed a bug that caused identification of main .cpp files in unity files to fail, leading to duplicate symbols being defined when trying to hot-reload.

  Thanks to Daan Niphuis and Simon Coenen from Guerrilla Games for bringing this to our attention.

• Fixed a bug where patches would fail to link in cases where the typeinfo of a vtable would be stored in an external translation unit.
• Fixed patching of relaxed relocations using RIP-relative GOT entries.

  Thank you to Daan Niphuis and Simon Coenen from Guerrilla Games for reporting this.

• Fixed thunk code inserted for certain relocations so that it no longer clobbers locals in the red zone in leaf functions.

  Thank you to Simon Coenen from Guerrilla Games for reporting this and helping with debugging.

2.9.1

April 22, 2025

Windows

• Implemented reconstruction of dynamic initializers whose mangled names contain an anonymous namespace identifier due to an MSVC compiler bug.

  Thanks to J-S Guay from Bethesda Game Studios for reporting this.

• Fixed a regression where a patch failed to load in the +-2GB range because reserved pages of one module could overlap reserved pages of another registered module.

  Thank you to Morten Hilker-Skaaning from Remedy Entertainment for bringing this to our attention.

• Fixed a Broker crash when trying to deoptimize a compiland for which the source file doesn't exist.

  Thank you to Raphaël Saint-Pierre from Ubisoft for reporting this.

• Fixed a bug where object file data would be evicted from the cache while an internal data structure still had a reference to it, leading to unexpected behavior or crashes.

  Thanks to Benj Carson from Critical Path Games for reporting this and helping with debugging.

2.9.0

April 8, 2025

Windows

• Initial release of support for PlayStation 4.
• Initial release of support for Xbox One.
• Added localization for Japanese, Chinese, and Korean.
• Added timestamp, process command line, thread ID and thread name to exception handler dialog.

  Thanks to Sebastian Schöner from kerntief for suggesting this.

• Completely reworked documentation to only use plain HTML & CSS, no Javascript or 3rd-party dependencies.
• Updated documentation to include -fstandalone-debug as required compiler option for Clang-cl and Clang++.

  Thank you to Daniel Castonguay from Ubisoft Montreal for bringing this to our attention.

• Implemented handling of Clang's "EH CatchRet" symbol.

  Thanks to Jonathan Allard for reporting this issue.

• Improved symbolication of callstacks in the exception handler, with improved error handling.
• Vastly improved handling of function static variables, especially in conjunction with the __LINE__ preprocessor macro.

  Due to how the compiler internally handles initialization of static block variables, function static variables would not get initialized properly when being renamed.

  Thanks to Alexander Torstling from Mojang for bringing this to our attention.

• Fixed a bug where relocations to functions would not be redirected to the thunk inserted by the linker when linking with /INCREMENTAL, making function pointer equality tests fail after a hot-reload.

  Thank you to Tobias Sicheritz and Sergey Hakobyan from Mi'pu'mi Games, as well as Alexander Torstling from Mojang for reporting this.

• Fixed a bug where reserved page regions would not be cleared correctly when a module was registered and then unregistered, without the Broker getting a chance to update its data structures in between.

  Thank you to Alexander Torstling from Mojang for reporting this issue.

• Fixed a bug where multiple compiler processes spawned by the Broker would inherit the same stdout handle, leading to increased compile times during unity splitting.

  Thanks to Daniel Lobo from Mojang for bringing this to our attention, and special thanks to Ritesh Oedayrajsingh Varma from Superluminal for helping with debugging this issue.

• Fixed a bug where internal data structures would store duplicates in case a unity file includes several translation units with the same filename, but from different directories.
• Fixed a bug where internal data structures would store duplicated compilands in case a translation unit appears more than once in the list of modules in a PDB.

  This can happen when several static libraries are linked into an executable using /WHOLEARCHIVE.

• Fixed a bug where the Agent would hang while waiting for an action in the exception handler, in case the Broker was being terminated in the meantime.

  Thank you to Sebastian Schöner from kerntief for reporting this issue.

• Fixed a bug where the change notification handles would not get closed after the last module gets unloaded by the Broker.

  Thanks to Daniel Lobo from Mojang for bringing this to our attention.

• Fixed a rare race condition when two threads in the Bridge would try to send network blobs to the Broker at the same time.
• Fixed a rare deadlock when trying to load modules while compilation is in progress.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for reporting this.

Xbox One® and Xbox Series X|S®

• Upgraded to latest GDK (October 2024).
• Added progress bar dialog when publishing the Broker IP address to targets.

  When Xbox targets are turned off, this operation can take a long time, potentially making users believe that the Broker has crashed.

• Improved logs when publishing the Broker IP address to default targets.
• Improved spawning of deferred process during Hot-Restart by waiting until all processes have terminated.
• Fixed a silent crash while trying to load Xtf* DLLs from the "GameDK\bin" directory, when the call to AddDllDirectory was unsuccessful.

  Thanks to Resmi Hasankolli and Tristan Bell from Electronic Arts for bringing this to our attention.

PlayStation®4 and PlayStation®5

• Implemented support for spawning the Broker on the host from within the Agent, respecting the corresponding project preferences.

  Thank you to Simon Coenen from Guerrilla Games for suggesting this.

• When attaching the VS debugger to the process, the Broker now also uses the --redacted-- IP address.

  This will make Hot-Restart work in cases where the target does not use --redacted-- mode.

• Improved stability when resuming a hot-restarted process in the VS debugger.
• Fixed a bug where ELF paths would not be canonicalized when registering a process.

  This improves readability of the produced logs.

• Fixed a bug where linking of patches would fail in case the linker working directory points to a directory that is not writable.

  When linking a patch, the stubs generated for the patch will now always be put into the same directory as the patch itself by using --redacted--.

2.8.1

January 15, 2025

Windows

• Fixed a rare bug that could lead to duplicate symbols being pulled into a patch from static libraries when linking against the static runtime.

  This could happen when defining operator delete with an explicit size argument in a static library.

  Thanks to Dan Ogles and Marcin Undak from Blizzard Entertainment for reporting this.

• Fixed a rare bug where a data symbol could move between .bss and .data sections depending on optimization settings, potentially leading to a crash after deoptimization.

  Thanks to Sebastian Schöner from kerntief for bringing this to our attention.

• Fixed a rare bug where a data symbol without a dynamic initializer could end up in a different data section after deoptimization, which could lead to reinitialization of the original symbol.
• Fixed a bug which would populate the Broker Exception Handler dialog twice in case the module base of the topmost stack frame is zero.

  Thanks to Sebastian Schöner from kerntief for reporting this.

• Improved Dark style UI for better visibility of certain elements.
• Improved color accents for drag/drop markers.

  Thanks to Sebastian Schöner from kerntief for suggesting this.

• Improved documentation regarding examples.

  Thanks to Sebastian Schöner from kerntief for suggesting this.

• Added thread ID to log files.

PlayStation®5

• Fixed a bug where a file handle would not be closed in case the file size could not be retrieved.

2.8.0

December 2, 2024

Windows

• The exception handler in the Broker will no longer write a crash dump for EXCEPTION_IN_PAGE_ERROR errors, but will output a warning instead.

  This was done because running Live++ from portable USB drives or network drives could generate a lot of crash dumps otherwise, filling up disk space.

  Thank you to Simon Moos from Hello Games for reporting this behaviour.

• Implemented check whether IPI stream is contained in the PDB file.

  Thanks to Sebastian Schöner from kerntief for reporting this bug and providing an implementation in the RawPDB library.

• Fixed a bug where Live++ would try to recompile a file that has been removed.

  Thanks to Sergey Hakobyan from Mi'pu'mi Games for reporting this.

• Fixed a bug where modules could appear twice in the array of modules to be enabled when using the LPP_MODULES_OPTION_ALL_IMPORT_MODULES option.

  This was caused by deduplication not working correctly when DLLs would appear in a certain order.

  Thanks to Alexandre Ganea from Haven Studios for reporting this.

• Fixed a bug where after failing to link, split compilands would not be compiled again even if required.

  Thank you to Sebastian Schöner from kerntief for bringing this to our attention.

• Fixed a bug where Hot-Restart would time out when the process was not being debugged in Visual Studio or Rider.
• Fixed a bug where cleared shortcuts could spontaneously trigger Hot-Reload or Hot-Restart operations.

  Thanks to Alexandre Ganea from Haven Studios and Mark Christoforetti from Blizzard Entertainment for reporting this.

• Implemented tooltip for command-line when hovering over the command-line column in the processes view.

  This helps when working with processes that use very long command-line options.

  Thanks to Sebastian Schöner from kerntief for suggesting this.

• Implemented tooltips for Module and Process views.
• Implemented workaround for breaking behaviour introduced in the VS2022 (17.11) debugger.

  Thanks to Sebastian Schöner from kerntief and Neil Wallace from Hello Games for reporting this.

• Improved documentation regarding default Hot-Restart shortcut.
• Improved documentation regarding global variables in the debugger.
• Improved documentation regarding using FASTBuild with Clang.

  Thanks to Olly Ginger from Electronic Arts for bringing this to our attention.

• Improved documentation regarding a recent Visual Studio Hot Reload option that will bring up a potentially confusing dialog.
• Added message box when changing any of the global preferences that require processes to be restarted for the changes to take effect.

  Thanks to Sebastian Schöner from kerntief for suggesting this.

• Added logging of errors for all VirtualAlloc* APIs used internally.
• Added logging of PDB filenames whenever an error occurs when trying to read DBI and IPI streams.
• Removed zero-sized custom.js from documentation.

  Thanks to Alexandre Ganea from Haven Studios for bringing this to our attention.

PlayStation®5

• Improved compatibility with more recent versions of the SDK (10.00+).
• Fixed a bug where not all contributions would be stored in case the DWARF .debug_aranges table started with tuples at address zero.

  This could lead to wrong behaviour or possibly crashes during a hot-reload.

• Fixed a bug where after registering a process with Live++, it was no longer possible to attach the debugger to the process.

  Thanks to David Ramos de la Fuente from Guerrilla Games for reporting this.

2.7.2

September 20, 2024

Windows

• Re-deployment of 2.7.1 release, which unfortunately had a mix of 2.7.0 and 2.7.1 in its build.

2.7.1

September 20, 2024

Windows

• Implemented dedicated support for JetBrains Rider IDE.

2.7.0

September 10, 2024

Windows

• Breaking API change: The Agent::Restart() API now takes an optional argument for command-line options being passed to the hot-restarted process.
• Optimized usage of buffers in thread-local storage.

  While primarily leading to faster loading of plugin DLLs and Agents using fewer TLS slots, this also has the benefit of fixing potential crashes in situations where thread-local storage in the Agent DLL hasn't been initialized yet, such as when calling DbgUiRemoteBreakin.

• Implemented detection of cases where DLLMainCRTStartup is not being linked correctly into patches.

  Thank you to Ales Mlakar for the repro project.

• Implemented blacklist for certain applications like CrowdStrike Falcon and ESET which have been reported to cause problems and crashes several times.
• Implemented debug menu to aid with troubleshooting and bug reporting.

  Thanks to Leonardo Santagada from Guerrilla Games for the idea.

• Implemented verbose compiling and verbose linking modes in debug menu.
• Implemented dumping of used project preferences in debug menu.

  Thanks to Sylvain Audi from Ubisoft Montreal for helping with this.

• Fixed module details not showing correctly in certain cases.

  Thanks to Marc Aubert from Eugen System for reporting this.

• Fixed Broker exception handler message box not being shown in case the main thread crashes.
• Fixed a bug where after changing any project preferences that could potentially alter the outcome of a database loading operation, loaded data would erroneously still be fetched from the database cache.

  Thanks to Leonardo Santagada from Guerrilla Games for reporting this.

• Fixed a bug where a temporary data structure was not large enough in case almost all files needed to be recompiled, leading to a crash in the Broker.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for reporting this.

• Added Troubleshooting section to documentation.
• Reworked docking system.
• Updated examples to latest version of Clang and LLD.

PlayStation®5

• Added support for reading an optional linker working directory file.
• Fixed a bug where unescaping the DWARF producer string would misinterpret trailing slashes.

  Thank you to Grayson Clark from Blizzard Entertainment for reporting this.

• Fixed patching of R_X86_64_(REX)_GOTPCRELX relocations which are not MOVs or LEAs.

  Thank you to Simon Coenen from Guerrilla Games for reporting and helping with this.

2.6.1

July 22, 2024

Windows

• Added support for using all available physical cores during compilation.
• Fixed unnecessary delay caused by retrying to open locked executable files before rebasing when installing patches into multiple processes.
• Fixed a bug where reconstruction of COMDAT-relative symbols could generate wrong symbol addresses.

  Thank you to Jim Kjellin from MachineGames for reporting this.

2.6.0

July 9, 2024

Windows

• Added support for specifying OPT:NOREF and OPT:NOICF options later in the command-line for overriding defaults or previous options.

  Thanks to Florian Schmiderer from Mi'pu'mi Games for reporting this.

• Fixed a bug that could lead to an overflow and subsequent crash if a module does not contain any dynamic initializers, and CRT sections are larger than 8 bytes.

  Thanks to Dan Printzell from dagg.ai for reporting this.

• Fixed a bug where reserved page regions would not be freed for processes that stay open, continually load and unload modules, creating and destroying agents in between.

  This required users of non-Live++ aware applications like Unity to restart the application, even though their Live++-enabled modules were correctly loaded and unloaded.

  Thank you to Edward Lambert from Sports Interactive for reporting and helping with this.

• Fixed a bug where waiting for the Agent to exit before deleting patch files in the Bridge could lead to a subsequent hang during the next hot-reload for a reloaded DLL.

  Thank you to Edward Lambert from Sports Interactive for reporting this.

• Fixed a bug where a temporary data structure had too little space during symbol reconstruction from object files, leading to a potential crash due to an out-of-bounds access.

  Thank you to Daniel Jennings from Valve for bringing this to our attention.

• Fixed a bug where after deleting PDB files with FILE_FLAG_DELETE_ON_CLOSE, subsequent hot-reloads on the same process would fail because the PDB file could not be written to.

  Thank you to Julien Charbonneau from Quantic Dream for reporting this.

• Fixed a bug where symbol reconstruction would not check for false positives, leading to wrongly reconstructed symbols in some cases, potentially patching unrelated code in a bad and unpredictable way.

  Thank you to Raphaël Saint-Pierre and Daniel Castonguay from Ubisoft for reporting this.

• Fixed a bug that would cause the exception handler to hang while symbolicating the callstack.

  Thank you to Edward Lambert from Sports Interactive and Leonardo Santagada from Guerrilla Games for reporting this.

• Fixed a race condition where a synchronized socket would try to abandon its operations, but had already been deleted behind the scenes because the patch process relinquished its ownership already.

2.5.2

May 22, 2024

Windows

• Implemented support for PDBs with nil stream indices.

  This makes the PDB reader more robust against (partially) corrupted PDBs.

  Thanks to Alexandre Ganea from Haven Studios for bringing this to our attention.

• Implemented source path filters for compilands.

  This is useful for ignoring automatically generated code files, such as Unreal Engine's .gen.cpp.

• Fixed a bug where hot-deoptimize would remove parts of user-defined preprocessor definitions that contain "/O".

  Thanks to Hamza Sood from Criterion Games for reporting this.

2.5.1

May 6, 2024

Windows

• Fixed potential crash when calling patch entry point.

  Thank you to Billy Khan from id Software for reporting this.

PlayStation®5

• Improved documentation and error messages regarding required .d dependency files.

  Thank you to Matt Stafford from mod.io for bringing this to our attention.

2.5.0

April 29, 2024

Windows

• Initial release of support for PlayStation®5.
• Fixed Broker not being spawned from Agent/Bridge.

  Spawning the Broker no longer uses the CREATE_BREAKAWAY_FROM_JOB flag.

• Fixed a bug where unnamed blocks could be considered valid candidates during symbol reconstruction.

  In the worst case, this could lead to false positives, resulting in relocations being patched at wrong offsets.

  Thank you to Raphaël Saint-Pierre and Daniel Castonguay from Ubisoft for reporting this.

• Optimized behaviour for processes consisting of several modules when using LPP_RELOAD_OPTION_SYNCHRONIZE_WITH_RELOAD.

  Thank you to Daniel Jennings from Valve for the feedback and discussions regarding this change.

• Implemented timeout when waiting for signals from the Broker.

  In some cases, packets could be blocked by firewall rules, making the Agent hang in LppEnableModule while waiting for a signal.

  Thank you to Luis Angel Mex and Chris Cooper from Turn 10 Studios for bringing this to our attention.

• Implemented reconstruction of symbols relative to COMDAT sections.

  This is much faster and more robust than trying to determine the symbol RVAs by binary section matching.

• Improved messaging and flow when a license has expired.

  Thank you to Hans Sjunnesson for suggesting this.

Xbox Series X|S®

• Added option to toggle UDP broadcasts for identifying the Broker IP address.

  This can be configured in the UI tab in the global preferences for Xbox Series X|S.

  Thank you to Chris Cooper from Turn 10 Studios for suggesting this.

2.4.1

March 18, 2024

Windows

• Optimized loading times.

  Since most build systems output all object files into the same directory, Live++ uses this as an opportunity to fetch several file attributes at once.

• Optimized patching performance.
• Improved documentation.
• Added showing progress in the task bar.

  This can be configured in the UI tab in the global preferences.

  Thank you to Tom Read Cutting from Hello Games for suggesting this.

• Added showing a message box when versions don't match between the Agent and the Broker.

  This can be configured in the UI tab in the global preferences.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for suggesting this.

• Fixed a crash in the 64-bit version of the Bridge when trying to read project preferences published from a 32-bit Agent process.

  Thank you to Tom Bui from Valve for reporting this.

• Fixed a race condition between the pre-patch hook and Update() function in the examples.

Xbox Series X|S®

• Added a dialog to publish the Broker IP address to several targets at once.

  Thank you to Jack Lair from Turn 10 Studios for suggesting this.

• Fixed wrong links in FAQ.
• Fixed wrong size of default heap.

  The default heap tried to use 128MiB, which was a remnant from the Windows version.

  Thank you to Michael Bartnett from Activision Blizzard for reporting this.

2.4.0

January 26, 2024

Windows

• Resurrected support for x86/Win32 applications.
• Breaking API change: The WantsReload() API now offers options to either synchronize with compilation and hot-reload, or just hot-reload.

  Consequently, the CompileAndReloadChanges() API has been renamed into Reload() as well.

  Thank you to Daniel Jennings from Valve for the feedback and discussions regarding this change.

• Added global hot-restart shortcut CTRL+ALT+R.

  This can be configured in the Hot-Restart tab in the global preferences.

• Added shortcuts to all action buttons in the exception handler dialog.

  Additionally, the dialog now focuses on "Leave function" by default and will also remember the last selected action.

• The Broker version is now shown in the window title.
• Fixed patching of section-relative relocations with non-zero destination offset.
• Fixed horizontal scrolling in Module view.
• Fixed determining whether a SEH state is available in exception handler.
• Fixed serialization of licensing options.

  Changing any of these options never had an effect, because they weren't serialized correctly into the global preferences file.

  Thank you to Sylvain Audi from Ubisoft Montreal for reporting this.

2.3.3

November 30, 2023

Windows

• Fixed a bug where the Bridge would try to access named shared memory that the Agent had already freed.

  Thank you to Kyle Rocha from Jetpack Interactive for reporting this.

• Fixed possible LNK2011 in native toolchain after having recompiled a PCH during a Live++ session.

  The PCH is now recompiled so that it can be used by the native toolchain (e.g. Visual Studio) after the Live++ session has ended.

  Thank you to Rick van Miltenburg from Triumph Studios for reporting this.

• Fixed rare bug where stripping internal functions from a patch would lead to a crash in the hot-reloaded code.

  Thank you to Billy Khan from id Software for reporting this.

• Fixed rendering artefact in examples.

Xbox Series X|S®

• Fixed project preferences being loaded from the wrong directory on the target.

2.3.2

October 12, 2023

Windows

• Improved handling of dynamic initializers when compiling with Clang.
• Improved handling of RTTI Complete Object Locators when compiling with Clang.
• Fixed "unknown warning group '-Wreserved-identifier'" warning on older versions of Clang.

  Thank you to Jim Kjellin from MachineGames for reporting this.

• Fixed reading of large PDBs that contain nil pages.

  Thank you to Sebastian Schöner from Epic Games for reporting this.

• Implemented resetting the notification tray icon to its default state as soon as the last registered target exits.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for suggesting this.

Xbox Series X|S®

• Agent and Bridge no longer have any dependencies on the Xbox runtime.
• The published Broker IP file is now stored in a human-readable format that can be opened with any text editor.

  Thank you to Maxime Thibeault from WB Games Montreal for suggesting this.

• Fixed an issue that would cause XUserFindForDevice() and other APIs to fail.

  Because of a limitation of XGameRuntimeInitialize() and the Xbox Gaming Runtime Services APIs, message boxes are no longer shown by the Bridge process, but in the Agent process instead.

  Thank you to Billy Khan from id Software for reporting this.

2.3.1

September 7, 2023

Windows

• Improved interoperability with anti-virus software that scans produced patch executables.

  In certain situations, patch executables could sometimes not be opened for READ/WRITE access because of anti-virus software locking the file during scanning. Live++ now employs a simple backoff and retry logic, and reports any process that might be holding a lock onto a patch executable.

  Thank you to the teams at Ubisoft for reporting this.

• Fixed Broker not staying open when being spawned from parent processes using a Win32 job object.

  Spawning the Broker from the Live++ Agent breaks away from any job object the parent process might be associated with.

  Thank you to Julien Charbonneau from Quantic Dream for reporting this.

• Fixed header in documentation not being responsive on mobile devices.

  Thank you to Jon Stevens for reporting this.

• Fixed reading of PDBs larger than 4GB.

  When trying to read PDB stream data starting at offsets >4GB, an internal calculation would overflow, resulting in the wrong offset(s) being used for subsequent reads. This bug would only manifest itself if the data to be read would actually start at an offset >4GB in the file, so it was subject to how the linker laid out the data in the PDB. (See GitHub commit)

  Thank you to Ritesh Oedayrajsingh Varma and Jelle van der Beek from Superluminal for reporting this, and Sebastian Schöner from Epic Games for helping with debugging this issue.

• Fixed reading of PDBs with symbols other than S_PUB32 in their public symbol stream.

  Thank you to Sebastian Schöner from Epic Games for reporting this.

• Added colorized icons in the notification area showing whether the last operation was successful or not.

  This can be configured in the UI tab in the global preferences.

  Thank you to Jonas Tärnström from MachineGames for suggesting this.

• Added detection of relative jumps when modules are disabled and enabled without unloading in between, which would otherwise lead to confusing "Not enough space" warnings.

  Thank you to Sloan Phillippi from Grinnelli Designs LLC for bringing this to our attention.

• Added support for storing Studio and Enterprise licenses in the %LocalAppData% folder.

  Thank you to Jack Knobel from Electronic Arts for suggesting this.

• Added support for providing a global_preferences_default.json file.

  Thank you to Sylvain Audi from Ubisoft Montreal for the discussions and feedback on this.

• Added project preferences for setting the directory to the Broker.

  This can be used for having the Live++ runtime (Agent and Bridge) reside in a different directory or even different drive than the Live++ Broker.

  Thank you to Jack Knobel from Electronic Arts for suggesting this.

• Added "What's New?" entry to main menu.
• Removed loading of global preferences from the legacy %LocalAppData%\Live++ 2 folder.
• Moved preferences spawnBrokerForLocalConnection and showErrorOnFailedBrokerConnection from global to project preferences.

  Thank you to Jack Knobel from Electronic Arts for the discussions about this.

Xbox Series X|S®

• Updated documentation regarding "GameDK" and "GameDKLatest" environment variables.
• Added an error message when "GameDK" environment variable is not available.

  Thank you to Billy Khan from id Software for reporting this.

• Connections to the default target no longer need to rely on UDP broadcasts alone.

  You can now use "Tools -> Xbox Series X|S -> Publish Broker IP address on default target", which will create a file storing your Broker's IP address on the System Scratch drive of the default target that will be picked up by the Live++ Agent when connecting to the Broker. In this case, no UDP broadcast will be performed.

  Thank you to Billy Khan from id Software for suggesting different methods of connecting hosts with targets.

• The "Agent/XSX" subdirectory for Agent and Bridge on the Xbox target is no longer required.

  The Live++ Agent and Bridge can be stored anywhere on the Xbox target now.

  Thank you to Billy Khan from id Software for suggesting this.

2.3.0

August 8, 2023

Windows

• Initial release of support for Xbox Series X|S®.
• Line numbers which encode debugger metadata are now supported by the exception handler.
• Optional global_preferences_override.json file allows clients to override global preferences.

  This allows teams to set up certain preferences for the whole team, while still allowing individual people to configure the remaining preferences as they see fit.

  Thank you to Sylvain Audi from Ubisoft Montreal for the discussions and feedback on this.

• Very large reduction in Broker startup times, all licensing has been moved into separate DLLs.
• Exception handler now shows correct symbolicated callstacks for modules for which DbgHelp cannot locate the PDBs.

  Thank you to Timo Suikat from Brickadia for reporting this.

• Unreal Engine 5 support has been improved by adding preferences for removing the "-sourceDependencies" compiler option.

  Thank you to Timo Suikat from Brickadia for bringing this to our attention.

• Support for CLR/C# DLLs that contain regions with page protection zero has been added.

  Thank you to Jack Knobel from Electronic Arts for reporting this.

• Queue used by the task system no longer causes extremely rare random crashes caused by a stale read.
• Unified API: API files and documentation files have been moved into platform-specific subfolders.

  This was a requirement to ensure that plugins for different platforms don't overwrite files of other existing platforms.

• Emitting -object-file-name compiler option when recompiling for Clang-based compilers.

  Thank you to Sylvain Audi from Ubisoft Montreal for the discussions and feedback on this.

• API change: APIs for creating agents now accept local preferences.

  Clients that don't require to change local preferences can simply pass nullptr as argument.

• Key message boxes for connection errors and crash dumps now always stay on top.

  Thank you to Sylvain Audi from Ubisoft Montreal for reporting this.

2.2.1

July 12, 2023

• Fixed a bug where unity splitting would consider compiling the PCH file again, leading to multiple defined symbols.

  Thank you to Martin Matouš from Warhorse Studios for reporting this.

• Fixed a bug where /EXPORT directives would not be stripped from PCHs after those have been recompiled at least once, leading to unresolved linker errors.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for reporting this.

• Fixed a bug where compilands that failed to spawn the compiler would not be recompiled without modifying the corresponding source file again.

  Thank you to Sylvain Audi from Ubisoft Montreal for bringing this to our attention.

• Added protection against LNK4099 and possible subsequent crash.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for reporting this.

• Added protection against Clang/LLD toolchains producing patch PDBs without any translation units.

  Thank you to Sylvain Audi from Ubisoft Montreal for bringing this to our attention.

• Added support for global hot-reload start and end hooks.

  Thank you to Bobby Anguelov and Daniel Jennings from Valve for suggesting this.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for suggesting this.

2.2.0

June 19, 2023

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for reporting this.

• Fixed log output when loading modules built with LTCG.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for bringing this to our attention.

• Fixed notification area icon not showing tooltip on hover.
• Fixed plugins not loading when using a different Broker working directory.

  We also added an error message in case no platform plugin can be loaded to make diagnosing this easier in the future.

  Thank you to Jorel Ali and Richie Hindle from Cyberscience for reporting this.

• Breaking API change: Make all Enable*() and Disable*() API calls accept a filter callback and context.

  Filtering of modules was previously only available for the EnableAutomaticHandlingOfDynamicallyLoadedModules() API, but that only allowed one filter pattern and only had support for built-in Windows wildcards. In order to support more patterns like e.g. regular expressions and allow filtering non-dynamically loaded modules as well, this change was introduced.
  Clients that don't require any filtering can simply pass nullptr for both callback and context.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for suggesting this.

• Breaking API change: Removed LPP_STRING_PREF_NETWORK_HOST_OR_IP.

  Since the Agent and Broker must already be connected in order to call the corresponding API, it does not make sense to alter this preference - it would not have any effect.

• Amended required Clang compiler options with -Xclang -mno-constructor-aliases.

  This compiler option is required to disable some internal compiler optimizations that behave similar to ICF, folding/aliasing constructors and destructors.

  Thank you to Sylvain Audi from Ubisoft Montreal for investigating this.

• Significantly improved Broker start times.

  Some people were having problems with the default connection timeout, because the Broker took to long to start when being spawned by the Bridge.

  Thank you to Neil Wallace from Hello Games for bringing this to our attention.

• Attaching the debugger to a hot-restarted process now makes the Visual Studio debugger behave as if it had spawned the process itself.

  The restarted process will automatically be terminated once debugging stops.

  Thank you to Jeremy Laumon from Guerrilla Games for suggesting this.

• Attaching the debugger after a Hot-Restart now happens on a suspended process.

  Breakpoints set early in the restarted process will no longer be missed.

  Thank you to Jean Farines from Asobo Studio for reporting this.

• Added hex addresses to exception handler callstack.
• All patch-related errors in the Agent are now also reported in the Broker UI log

  Thank you to Jean Farines from Asobo Studio for suggesting this.

• Added information about available SEH data to exception handler.

  Thank you to Jean Farines from Asobo Studio for suggesting this.

• Added animated icon in notification area during Hot-Reload and Hot-Restart.

  This can be toggled in the "UI" tab of the global preferences and is on by default.

  Thank you to folks at Asobo Studio for requesting this to be brought back.

• Added linker command-line options to Module details dialog.

  Thank you to Tobias Sicheritz from Mi'pu'mi Games for suggesting this.

• Changed Bridge UI style to be Dark instead of Light by default.

  This matches the default Broker settings.

• Updated documentation with 30-day trial workflow.

  Thank you to Ryan Juckett for suggesting this.

• Added log output when saving preferences.
• Added platform identifier to the Broker UI log.
• Added target and process ID to Process view.
• Added target and process ID to Compilands view.
• Added platform and language to all dialog window titles.

  These changes were done in anticipation of upcoming releases of Live++ for consoles.

2.1.5

May 17, 2023

• Fixed hang when copying from the Broker UI log.

  This was caused by 3rd-party copy protection corrupting Qt's internal messaging system.

  Thank you to Zsolt Molnar from Creative Assembly for reporting this.

• Fixed hang during Hot-Reload when breaking into the Visual Studio debugger using either __debugbreak() or an INT3 instruction.

  Thank you to Neil Wallace from Hello Games for reporting this.

• Fixed Hot-Restart not reattaching the Visual Studio debugger to the hot-restarted process.

  Due to a race between two code paths trying to exit the Bridge, the code for reattaching the Visual Studio debugger would sometimes not be able to run.

  Thank you to Felix Erksell from Massive Entertainment for bringing this to our attention.

• Fixed Broker instances being spawned for applications running as Windows Services.

  The global mutex that is used for detecting whether a Broker is already running was not global across Windows Services, leading to situations where multiple Brokers would be listening for incoming connections on the same port.

  Thank you to Richie Hindle from Cyberscience for reporting this.

• Fixed Agent exception handler not getting unregistered correctly in case "Leave function" has been used at least once.

  When an exception handler is called by the operating system, its internal reference count gets incremented internally to make sure that it isn't removed while being called (see ReactOS source). However, when using the "Leave function" option, the reference count is never decremented again because unwinding the stack does not continue execution at the original call site.

  Thank you to Edward Lambert from Sports Interactive for reporting this.
