+## [0.3.0] - 2024-07-31
+
+* Update `rand_core` dependency to exactly `0.6`, dropping support for `rand_core <= 0.5`. This
+  works around Cargo issues where unrelated updates can cause the `rand_core` dependency to "snap
+  back" to older versions.
+
 ## [0.2.3] - 2022-02-24
 Fix undefined behaviour caused by narrowing provenance of slice pointer to a
 single element then reading multiple elements (#8).
