This is a huge release in terms of code redesign bringing in a lot of features for diagnostic/maintenance of devices together with state-of-the-art bug fixes and some new features/supported devices. Let's see what's new:

New features

• supported Meross multi-factor-authentication (for accounts so configured) (#372)
• supported the mts960 Smart Thermostat plug (#356)
• supported the map100 Smart Air Purifier (#388)
• supported the Child-Lock feature for devices exposing it
• added the ability to configure device MQTT binding (so to link it to the same HA MQTT broker and 'discard' Meross cloud MQTT) without the need of external utilities/app

Improvements

• device communication has been improved in order to reduce the number of exchanged messages thus improving latency and (hopefully) overall communication performance
• added device timezone check and configuration to ease solve some (mss310 or any metering plug) issues (#367)
• logging and tracing completely re-done to give better control (at the device configuration level)
• added 'diagnostic sensors' (configurable per device) to automatically extract and show in HA UI the data exposed by any device for (still) unsupported features

Fixes

• almost any pending issue has been fixed (check its state in the issues registry)

Full Changelog: v4.5.3...v5.0.0
