## [Unreleased]


## [0.3.0] - 2024-02-05

### Added

- Native stack consolidation
  - Pf2 now records native (C-level) stacks during sample capture.
    - This functionality is based on [libbacktrace](https://github.com/ianlancetaylor/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.
