-## [Unreleased]
+## [0.2.0] - 2023-07-14
+
+### Changed
+
+* SHT4X regularly polls temperature and humidity at 5 second intervals
+  (configurable). Regular polling is required for temperature compensation
+  algorithms.
+* The `SHT4X.measure/1` function is now `SHT4X.get_sample/1` to reflect that it
+  returns the latest sample rather than polling the sensor. The `SHT4X.Measurement`
+  struct contains a timestamp and quality information to indicate how stale it
+  is. Staleness could be due to communication issues with the sensor or just
+  waiting for the next poll time.
+* The sensor's serial number is not polled on init. This means that I2C failures
+  or retry delays won't delay or fail startup. They likely will affect the
+  regular polling if they don't resolve themselves.
+
+### Added
+
+* `SHT4X.serial_number/1` to get the sensor's unique serial number
+* The sensor is immediately polled for a temperature. Previously the first
+  temperature measurement was delayed until the interval timer expired (default 5
+  seconds).
