 * New feature: Access interim results from counters without stopping the counter using [live counters](docs/recording-live-events.md).
 * New feature: Sampling the user stack (see [documentation](docs/sampling.md#user-stack)).
 
+## v0.8.2
+* Fixed compatibility for older Linux versions that don't provide `PERF_MEM_BLK`, `PERF_MEM_LVLNUM`, and `PERF_MEM_REMOTE`.
+
+## v0.8.1
+* Fixed error using decltype instead of typeof (by [@toge](https://github.com/toge))

   * Examples are no longer included into default build and must be activated with `-DBUILD_EXAMPLES=1` (see [documentation](docs/build.md#build-examples)). 
   * New feature: Added option to install the library using `-DCMAKE_INSTALL_PREFIX=/path/to/libperf-cpp` (see [documentation](docs/build.md#install-the-library)).
 * New feature: Define period or frequency along with trigger events when sampling (see [documentation](docs/sampling.md#period--frequency)).
