Sync beta support

This release is only for use with the open beta VRCSDK, if you are using live, use 0.19.5. If you are updating from UdonSharp <v0.19.2, you need to delete the Assets/UdonSharp/Plugins folder before installing this

• Add UI for manual sync vs continuous sync selection to UdonSharpBehaviour inspector
• Add warning and conversion for objects using the now-deprecated position sync option, in favor of using the new VRC Object Sync component instead
• Add UdonBehaviourSyncMode attribute to optionally enforce a chosen sync mode and preform additional validation on synced variables
• Switch to use new Udon methods to check sync type compatibility (which allows use of the array sync)
• Add handling for calling RequestSerialization() on UdonSharpBehaviours
• Add handling for the OnOwnershipTransferRequest and OnPostSerialization events
• Add handling for the previous owner being passed to OnOwnershipTransferred
• Update sync utility scripts to use reliable sync
• Add build validation for sync mode conflicts

Midi & Input event support

Make sure you have the most recent VRCSDK3. If you are updating from UdonSharp <v0.19.2, you need to delete the Assets/UdonSharp/Plugins folder before installing this

• Add support for events added in the open beta: MidiNoteOn, MidiNoteOff, MidiControlChange, OnPlayerRespawn, InputJump, InputUse, InputGrab, InputDrop, InputMoveHorizontal, InputMoveVertical, InputLookHorizontal, and InputLookVertical
• 14ddda4: Fix case where recursive stack size reservations could be stomped on recursive methods, reported by @NGenesis

Udon open beta fixes

This release requires the open beta VRCSDK3 to work. Do not use this if you are not using the open beta SDK. If you are updating from an older version UdonSharp, you need to delete the Assets/UdonSharp/Plugins folder before installing this

• f1953ac: Fix conflicts with the latest VRCSDK due System.Collections.Immutable being required
• 316e41d: Add support for specifying execution order using the DefaultExecutionOrder attribute

Recursion support

As always, make sure you have the latest VRCSDK3 installed before upgrading U# or you may run into errors

Features

• aa79a63: Recursion support has been added to U#, you must mark any methods that will be called recursively with the [RecursiveMethod] attribute. This has an overhead so only use it when you need recursion, and consider converting your algorithms to be iterative if you are looking for performance.
• 17eb24f: Add handling for bitwise not operator ~
• 2af6f57: Add support for using foreach to iterate children of Transforms
• fda52e9: Add support for using Odin Inspector on UdonSharpBehaviours, you need to enable the Odin inspector handling in the UdonSharp settings in your project settings to use it by changing the Default Behaviour Editor option
• #65: Add support for overriding RequiresConstantRepaint in custom inspectors, contributed by @NGenesis
• a20391f b52c40c: Minor compile performance improvements

Fixes

• a99841a: Allow the binder to error about using nullable field declarations, reported by Narry
• 7c0f1a1: Fix regression preventing assigning VRC Video player components of non-base types, reported by @owlboy
• ed8a472: Handle when field initializers throw exceptions better
• 4dd037b: Fix exceptions piling up in the error field in some cases
• c923fdb: Sanitize script names more stringently when creating new scripts to prevent issues with Unity failing to recognize the class
• 96068ca: Better handle a case where array serialization while using custom inspectors could get broken more than it should.
• bf59eb2: Make custom inspector serialization a bit more lenient with types that are aliased internally by U#
• 0cb722a: Make Harmony unpatch methods before an assembly reload, this may help with one mode of failure that Mono likes to die on sometimes.
• 5b760c1: Make Exposure tree text white when highlighted so it's actually readable, requested by Mochie
• 5736673: Add more VRC log types that were added in recent patches to the log filter
• 991078a: Disable collision transfer by default when using AddUdonSharpComponent
• f4125e7: Add warning for when a script's file name does not match its class name since this causes many issues with Unity for some reason
• 1cf6156: Add warning when UdonSharpProgramAssets do not have a script assigned as people have gotten confused when they have a program asset setup without a reference
• b2eea00: Add warning dialog when changing the source script on an UdonSharpProgramAsset since it can cause things to break if it's in use
• a7a88db: Add warning for when multiple UdonSharpProgramAssets reference the same source script since this can cause the compiler to act in unexpected ways

Bug fixes

• c9c0ba5: Fix for Udon GetComponent bug that was causing GetComponent to throw errors depending on where the source object for the GetComponent came from.
• 980409f: Fix arrays of VRC components more
