• Added signature modes: you can now load the game with only a specific set of plugins; all signed and unsigned plugins, all signed plugins, all TMGL-approved plugins, and all official plugins. (Previously TMGL-approved plugins were available as a separate Openplanet build, but is now released publicly!)
• Added "enable window docking with shift" option to new "overlay" settings menu
• Added ability to create custom overlay styles
• Added experimental JIT compiler to speed up script execution with about 30% (must be enabled in the settings)
• Added slight script execution performance improvements
• Added a full Openplanet profiler to the debugger menu that can profile all plugins as well as Openplanet itself
• Added option to warn on hung plugin frames (recommended to enable when developing plugins)
• Performance should be a bit better overall
• Fixed sometimes not being able to close nod explorer tabs
• Updated Angelscript and Curl

For developers:

• Added SQLite API
• Added ability to show custom icons on scripted settings tabs
• Added more support for Markdown in UI::Markdown
• Added UI::IsDockingEnabled
• Added UI::BeginListBox and UI::EndListBox
• Added UI::SliderDouble
• Added IO::FileModifiedTime
• Added format parameters to UI slider functions
• Added Math::IsNaN, Math::IsInf, Math::SwapBytes, Math::Slerp
• Added more functions to the quat class to make it much more useful
• Added Net::HttpRequest::Error
• Added Net::SecureSocket::Write with MemoryBuffer
• Added MemoryBuffer::WriteFromBuffer and MemoryBuffer::ReadBuffer
• Added CMwStack::CurrentBufferX functions
• Added Meta API to get required and optional plugin dependencies
• Added common vector swizzles: vec3::xy, vec4::xyz, int3::xy, nat3::xy
• Added support for double setting types
• Added experimental CGameNetwork::GetManialinkPages
• Added more profiling options to the debugger menu
• Json::Value is now a reference type instead of a value type, allowing more efficiently passing around objects
• Added void RenderEarly() callback to handle early rendering. This is useful for dependency plugins such as Camera that need to execute some logic during rendering, but don't necessarily have to render something.
• Added sanity check warnings for get_Property() method calls instead of .Property
• Added sanity check warnings for class methods that are missing override keywords
• Added sanity check warnings for string parameters in functions that are unnecessarily copied
• Fixed multi threaded plugin execution to be a little bit safer (but not completely safe)
• Fixed crash when calling Discord::GetUser before Discord is actually ready
• The Compatibility.as script is now only added to packaged .op plugins (to make sure developers don't use deprecated functionality during development)
• Upgraded some script imports to built-in API's: Permissions, Time, Formatting (importing them manually is now deprecated)
• Deprecated script imports are now skipped and throw warnings instead of importing an empty script
• Deprecated void RenderSettings() without [SettingsTab]

• Fixed crash when enabling developer mode

• Added "Developer Mode" - without this mode enabled, only signed plugins can be used
• Added await functions
• Added Meta::PluginIndex
• Added UI::HoveredFlags to IsItemHovered
• Added UI::CalcItemSize
• Added IO::FromStorageFolder
• Added the ability to pass around MemoryBuffer handles
• Updated Angelscript
• Fixed missing constness on a couple of class methods
• Fixed issues when reloading plugins with dependents from plugin manager
• Fixed some game binding problems
• Fixed wrong parameters on some IO::File::Write methods
• Fixed crash when passing null to UI::Image or AddImage
