-## 0.3.19 [2022-02-016]
+## 0.3.20 [2023-02-24]
+
+### Changed
+
+- The minimum supported Rust version is now 1.63.0.
+- On Unix-based operating systems with known thread-safe environments, functions obtaining the local
+  offset no longer require a check that the program is single-threaded. This currently includes
+  MacOS, illumos, and NetBSD.
+
+### Added
+
+- `[ignore]` component in format descriptions. A `count` modifier is required, indicating the number
+  of bytes to ignore when parsing.
+- `[unix_timestamp]` component in format descriptions. This is currently only usable with
+  `OffsetDateTime`. Users can choose between seconds, milliseconds, microseconds, and nanoseconds, and whether the sign is mandatory or optional.
+
+### Fixed
+
+- The API for declaring soundness now uses stricter atomic orderings internally.
+
+## 0.3.19 [2023-02-16]
 
 ### Fixed
 
 This includes the update to the `format_description!` macro, which was supposed to be included in
 0.3.18.
