 # *perf-cpp*: Changelog
 
-## v0.13.0 (WIP)
+## v0.13.0
 - **Header Restructuring**: Headers have been reorganized into `counter/`, `sample/`, `metric/`, `analyzer/`, and `util/` subdirectories and renamed from `.h` to `.hpp`. The previous `.h` headers remain as forwarding includes with deprecation notices and will be removed in v1.0.
 - **Breaking**: `EventCounter::add()` and `start()` (including `Sampler::start()` and all multi-thread/core variants) now return `void` instead of `bool`. Errors are communicated via exceptions; the return values were unused.
 - **Compile Flag for AUX Buffer Support**: Added `PERFCPP_NO_SAMPLE_AUX` compile flag to disable auxiliary buffer sampling on systems with Linux kernels older than 5.5 that lack `PERF_SAMPLE_AUX` support. Thanks to [@rconnorlawson](https://github.com/rconnorlawson).
