 # Changelog
 
+## [1.6.0](https://github.com/gavinying/modpoll/compare/v1.5.1...v1.6.0) (2025-12-06)
+
+
+### Features
+
+* add bit-level access for boolean registers ([cecf79d](https://github.com/gavinying/modpoll/commit/cecf79d24de79fdda7f524516fb163f35f392e3f))
+* add new argument 'serial' to support multiple framers, including rtu/ascii/binary. Keep the old 'rtu' argument as an alias to 'serial' argument for backward compatibility. ([d42ab78](https://github.com/gavinying/modpoll/commit/d42ab78801d16c96cde852686f77ec6694776cf9))
