  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

  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

  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 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.

  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.

  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.

  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.

2.1.5 - May 17, 2023
Download

• Fixed hang when copying from the Broker UI log

  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.
