Full Changelog: v0.17.1...v0.18.0

v0.17.1

Major updates

• Live heap mode is fixed (for leak investigations).
• Our Symbolization library has changed: we now rely on blazesym.
• We now have an option to retrieve inlining information -I,--inlined_functions
• Code locations are OFF by default. Instead they are triggered with the -I,--inlined_functions option. This is done due to the potential overhead of parsing debug information.
• PID mode is fixed (-p 1234).
• The performance of --global mode is improved which results better profiler accuracy (events are no longer missed). The RSS usage of full host is considerably improved by this release.

This is a pre-release. Please use this release in a non-critical environment.

v0.15.1

Major updates

• A major performance improvement on ddprof's RSS usage 📉
• Allocation profiling now follows child processes (even through execs)
  This means you can launch ddprof, before a bash script, before a python execution, before a ruby shim...
• Live heap performance improvement.
• Better startup instrumentation.
