  • Profiler: Added missing memory labels sizes to the memory snapshot format, in order to give real value to the prexisting label list. Api for access this data will be found inside the memory profiler package

  • Profiler: Added profiler memory stats data, data is similar to the Profiler Module data found in the Profiler Window

  • Profiler: Added profiler target data to memory snapshot format, data consists of elements such as unity version, product name, total gfx memory, total physical memory etc.

  • Profiler: Encoded managed heap section type inside the snapshot format, for retrieval via the memory profiler package

  • Profiler: Reworked native connection reporting for the memory profiler in order to properly report connections between assets

  • Version Control: - Stability and performance improvements
