iOSBreaking
PerformanceTestRunInfo.json and PerformanceTestRunSettings.json are no longer generated during player builds that do not include test assemblies, as they are only read by performance tests running inside the player.

Performance Test FrameworkBreaking
Remove deprecated BIRP support for PhysicsCore2D renderer.
Physics 2DBreaking
Removed the upgrade path for prefab data saved by Unity 3.3 or earlier, so prefab instances and per-object overrides in projects that old no longer survive being opened. Unity 6.7 warns when it loads an asset in that format.
PrefabsBreaking
DEVELOPMENT_BUILD preprocessor symbol no longer gets defined when building for any platform. Preprocessor symbols DEBUG, ENABLE_ASSERTIONS and ENABLE_PROFILER now only get defined in appropriate managed code variants (debug, checked and instrumented, respectively). BuildOptions.ForceEnableAssertions, CodeAnalysisFlags.DevelopmentBuild, ScriptCompilationOptions.DevelopmentBuild, ScriptCompilationOptions.Assertions and AssemblyBuilderFlags.DevelopmentBuild have been removed: script compilation is now only affected by the managed code variant.
ScriptingBreaking
