+## 0.2.26 [2021-03-16]

+### Fixed
+
+- #316, where the build script was wrongly unable to determine the correct compiler version
+- Dependencies have been bumped to the latest patch version, ensuring compatibility.
+
+## 0.2.25 [2021-01-24]
+
+### Fixed
+
+- Fix #309, which can cause panics in certain situations.
+
+## 0.2.24 [2021-01-08]
+
+### Fixed
+
+- The implementation of `OffsetDateTime::timestamp`, `OffsetDateTime::unix_timestamp`,
+  `PrimitiveDatetime::timestamp`, and `OffsetDateTime::unix_timestamp` have been corrected. This
+  affects all negative timestamps with a nonzero subsecond value.

+## 0.2.23 [2020-11-17]
+
+## Compatibility notes
+
+Due to #293, any method that requires knowledge of the local offset will now
+_fail_ on Linux. For `try_` methods, this means returning an error. For others,
+it means assuming UTC.
