Major changes:

• Deallocation backtraces are now gathered by default; you can use the MEMORY_PROFILER_GRAB_BACKTRACES_ON_FREE environment variable to turn this off
• Deallocation backtraces are now shown in the GUI for each allocation
• Allocations can now be filtered according to where exactly they were deallocated
• Allocations can now be filtered according to whether the last allocation in their realloc chain was leaked or not
• Profiling of executables larger than 4GB is now supported
• Profiling of executables using unprefixed jemalloc is now supported
• New scripting APIs:
  • AllocationList::only_matching_deallocation_backtraces
  • AllocationList::only_not_matching_deallocation_backtraces
  • AllocationList::only_position_in_chain_at_least
  • AllocationList::only_position_in_chain_at_most
  • AllocationList::only_chain_leaked
• The server subcommand of the CLI should now use less memory when loading large data files
• The behavior of malloc_usable_size when called with a NULL argument now matches glibc
• At minimum Rust 1.62 is now required to build the crates; older versions might still work, but will not be supported
• The way the profiler is initialized was reworked; this should increase compatibility and might fix some of the crashes seen when trying to profile certain programs
