  14  * Changes in major/minor versions:
  15  * version 1.0: removed sysid field from header
  16  *              added args, arch, os fields to header
  17  *
  18  * Changes in data versions:
  19  * version 2: added offsets in heap walk
  20  * version 3: added GC roots
  21  * version 4: added sample/statistical profiling
  22  * version 5: added counters sampling
  23  * version 6: added optional backtrace in sampling info
  24  * version 8: added TYPE_RUNTIME and JIT helpers/trampolines
  25  * version 9: added MONO_PROFILER_CODE_BUFFER_EXCEPTION_HANDLING
  26  * version 10: added TYPE_COVERAGE
  27  * version 11: added thread ID to TYPE_SAMPLE_HIT
  28                added more load/unload events
  29                    unload for class
  30                    unload for image
  31                    load/unload for appdomain
  32                    load/unload for contexts
  33                    load/unload/name for assemblies
  34                removed TYPE_LOAD_ERR flag (profiler never generated it, now removed from the format itself)
  35                added TYPE_GC_HANDLE_{CREATED,DESTROYED}_BT
  36                TYPE_JIT events are no longer guaranteed to have code start/size info (can be zero)
  37  * version 12: added MONO_COUNTER_PROFILER
  38  * version 13: added MONO_GC_EVENT_{PRE_STOP_WORLD_LOCKED,POST_START_WORLD_UNLOCKED}
  39                added TYPE_META + TYPE_SYNC_POINT
  40                removed il and native offset in TYPE_SAMPLE_HIT
  41                methods in backtraces are now encoded as proper method pointers
  42                removed flags in backtrace format
  43                removed flags in metadata events
  44                changed the following fields to a single byte rather than leb128
  45                    TYPE_GC_EVENT: event_type, generation
  46                    TYPE_HEAP_ROOT: root_type
  47                    TYPE_JITHELPER: type

  50                    TYPE_SAMPLE_COUNTERS_DESC: type, unit, variance
  51                    TYPE_SAMPLE_COUNTERS: type
  52                added time fields to all events that were missing one
  53                    TYPE_HEAP_OBJECT
  54                    TYPE_HEAP_ROOT

  59                    TYPE_COVERAGE_CLASS
  60                    TYPE_COVERAGE_ASSEMBLY
  61                moved the time field in TYPE_SAMPLE_HIT to right after the event byte, now encoded as a regular time field
  62                changed the time field in TYPE_SAMPLE_COUNTERS to be encoded as a regular time field (in nanoseconds)
  63                added TYPE_GC_FINALIZE_{START,END,OBJECT_START,OBJECT_END}
