v0.3.0

Added

• Native stack consolidation
  • Pf2 now records native (C-level) stacks during sample capture.
    • This functionality is based on libbacktrace.
• New configuration interface for Pf2.start, Pf2::SignalScheduler.start, Pf2::TimerThreadScheduler.start
  • They now accept keyword arguments (interval_ms, threads, time_mode, track_new_threads).
• New configuration options
  • interval_ms: The sampling interval.
  • time_mode (:wall or :cpu): The sampling timer's mode. :wall is wall-clock time (CLOCK_MONOTONIC to be specific), :cpu is per-thread CPU time (CLOCK_THREAD_CPUTIME_ID).

Removed

• Configuration through positional arguments is no longer supported.
