+## 0.1.5 - 2023-10-16
+
+- Added `links` key to Cargo.toml, to prevent multiple copies of this crate in the same binary.
+  Needed because different copies might get different tick rates, causing
+  wrong delays if the time driver is using one copy and user code is using another.
+  This is especially common when mixing crates from crates.io and git.
+
 ## 0.1.4 - 2023-10-12
 
 - Added more tick rates
