See [migration path](https://tasmota.github.io/docs/Upgrading#migration-path) for instructions how to migrate to a major version. Pay attention to the following version breaks due to dynamic settings updates:
While fallback or downgrading is common practice it was never supported due to Settings additions or changes in newer releases. Starting with release **v9.1.0 Imogen** the internal GPIO function representation has changed in such a way that fallback is only possible to the latest GPIO configuration before installing **v9.1.0**.
This release will be supported from ESP8266/Arduino library Core version **2.7.4.9** due to reported security and stability issues on previous Core version. This will also support gzipped binaries.
In addition to TLS using fingerprints now also user supplied CA certs, AWS IoT and Azure IoT is supported. Read [full documentation](https://tasmota.github.io/docs/AWS-IoT)
For initial configuration this release supports Webserver based **WifiManager** or **Serial** based command interface only. Support for **WPS** and **SmartConfig** has been removed.
