Releases

2.5.2 - May 22, 2024 DownloadDownload Examples

  • 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 DownloadDownload Examples

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

2.5.0 - April 29, 2024 DownloadDownload Examples

  • 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.

2.4.1 - March 18, 2024 DownloadDownload Examples

  • 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.

    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

2.4.0 - January 26, 2024 DownloadDownload Examples

  • 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 DownloadDownload Examples

  • 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

2.3.2 - October 12, 2023 DownloadDownload Examples

  • 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.

2.3.1 - September 7, 2023 DownloadDownload Examples

  • 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.

2.3.0 - August 8, 2023 DownloadDownload Examples

  • 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

  • Stack overflows handled by the exception handler no longer cause a misleading crash in the agent

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

2.2.1 - July 12, 2023
Download

  • 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.

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

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

  • Additional command-line options specified in the project preferences no longer require an extra whitespace

    This matches the behaviour from Live++ 1.x.

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

  • "Focus broker window upon" notifications now match the behaviour from Live++ 1.x

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

  • Improved log output to include the name of modules for successful and failed recompiles

    When several modules were registered in the Broker, the UI log was confusing in cases where some modules would be successfully recompiled, while others failed.

    Thank you to Martin Mais from Keen Games for reporting this.

  • Added release notes to deployment

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

2.2.0 - June 19, 2023
Download

    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.

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

2.1.5 - May 17, 2023
Download

  • 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.
