Version 3.6.4
Fixed d8's broken readline history.
Removed the need for code delete events in CPU profiler (Issue 1466).
Fixed debugger stepping next with trycatch recursion (Issue 1639).
Fixing parallel execution in d8 (with -p) and some memory leaks.
Support for precise stepping in functions compiled before debugging was started (step 1).
