+## [1.2.1] - 2021-02-18
+### Added
+- New constants RELATIONSHIP_CHILD, RELATIONSHIP_ROOT, and RELATIONSHIP_STANDALONE added to .const (and returned from the relationship property of HomeSeerStatusDevice).
+
+## [1.2.0] - 2021-02-16
+### Changed
+- The get_devices method in .devices has been refactored (along with the device classes) to provide "support" for all HomeSeer devices, regardless of device_type_string. The get_devices method no longer returns device objects based on device_type_string, but instead based on the Control Pairs detected for the device. This change makes libhomeseer completely agnostic as to the technology or plug-in that provides the device. All HomeSeer devices are now supported and libhomeseer will return at least a status-only object for every device. Devices with Control Pairs that fall into certain categories (initially On/Off, On/Off/Dim, and Lock/Unlock) will have an object returned with appropriate methods (e.g. on(), off(), dim(), lock(), unlock()) that match the device's detected Control Pairs.
+- The release.sh script now builds a wheel for the library in addition to the source distribution.
+
+## [1.1.0] - 2021-02-15
+### Added
+- New units Amperes, kW, Volts, and Watts to the get_uom_from_status helper function.
+
 ## [1.0.0] - 2021-02-08
 ### Added
 - First release of libhomeseer after deprecation of pyhs3.
