  10  * Changes in data versions:
  11  * version 2: added offsets in heap walk
  12  * version 3: added GC roots
  13  * version 4: added sample/statistical profiling
  14  * version 5: added counters sampling
  15  * version 6: added optional backtrace in sampling info
  16  * version 8: added TYPE_RUNTIME and JIT helpers/trampolines
  17  * version 9: added MONO_PROFILER_CODE_BUFFER_EXCEPTION_HANDLING
  18  * version 10: added TYPE_COVERAGE
  19  * version 11: added thread ID to TYPE_SAMPLE_HIT
  20                added more load/unload events

  26                removed TYPE_LOAD_ERR flag (profiler never generated it, now removed from the format itself)
  27                added TYPE_GC_HANDLE_{CREATED,DESTROYED}_BT
  28                TYPE_JIT events are no longer guaranteed to have code start/size info (can be zero)

  32                removed il and native offset in TYPE_SAMPLE_HIT
  33                methods in backtraces are now encoded as proper method pointers
  34                removed flags in backtrace format
  35                removed flags in metadata events
  36                changed the following fields to a single byte rather than leb128
  37                    TYPE_GC_EVENT: event_type, generation
  38                    TYPE_HEAP_ROOT: root_type
  39                    TYPE_JITHELPER: type
  40                    TYPE_SAMPLE_HIT: sample_type
  41                    TYPE_CLAUSE: clause_type
  42                    TYPE_SAMPLE_COUNTERS_DESC: type, unit, variance
  43                    TYPE_SAMPLE_COUNTERS: type
  44                added time fields to all events that were missing one
  45                    TYPE_HEAP_OBJECT
  46                    TYPE_HEAP_ROOT
  47                    TYPE_SAMPLE_USYM
  48                    TYPE_SAMPLE_COUNTERS_DESC
  49                    TYPE_COVERAGE_METHOD
  50                    TYPE_COVERAGE_STATEMENT
  51                    TYPE_COVERAGE_CLASS
  52                    TYPE_COVERAGE_ASSEMBLY
  53                moved the time field in TYPE_SAMPLE_HIT to right after the event byte, now encoded as a regular time field
  54                changed the time field in TYPE_SAMPLE_COUNTERS to be encoded as a regular time field (in nanoseconds)
  55                added TYPE_GC_FINALIZE_{START,END,OBJECT_START,OBJECT_END}
