 * **v0.8.2:** add ability to run Memory Trimming on demand
 * **v0.9:** New experimental feature: auto-threshold.  Designed to automatically adjust your thresholds to the target frequency.  If you try it out, please provide feedback at <https://github.com/henderea/MemoryTamer/issues/4>
 * **v0.9.1:** Make some changes to auto-threshold to hopefully improve it.  If you try it out, please provide feedback at <https://github.com/henderea/MemoryTamer/issues/4>
+* **v0.9.2:** fix a bug introduced in v0.9.1 where memory threshold would be set to 0 if trim threshold was 0
