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.

What's Changed

• Add logging to the library by @nsavoire in #359
