**Do not upgrade from minimal to minimal version. It will most likely fail at some point and will require flashing via serial.** If you do have to use minimal versions, always OTA to a full version of the same release before applying next minimal version.
4. Migrate to **Sonoff-Tasmota 6.7.1** (http://ota.tasmota.com/tasmota/release_6.7.1/sonoff.bin) - NOTICE underscore as a dash is not supported in older versions
5. Migrate to **Tasmota 7.2.0** (http://ota.tasmota.com/tasmota/release-7.2.0/tasmota.bin)
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)

- Command ``SetOption135 1`` to disable LVGL splash screen
- Command ``SetOption136 1`` to disable single sensor reports from Tuya devices while keeping teleperiod reports [#15216](https://github.com/arendst/Tasmota/issues/15216)
- HX711 command ``Sensor34 10 0|1|<weightingram>`` to set HX711 fixed tare (0 = use auto tare, 1 = use calibrated tare, Any other value is user selected tare)
- HX711 commands ``Sensor34 11 <valueA>`` and ``Sensor34 12 <valueB>`` to use HX711 absolute weight conversion [#15292](https://github.com/arendst/Tasmota/issues/15292)
- ESP32 TasmotaSerial uart mapping to support multiple ``begin()`` and implement ``getUart()`` [#14981](https://github.com/arendst/Tasmota/issues/14981)
- Remove support for Internet Explorer by allowing ECMAScript6 syntax using less JavaScript code bytes [#15280](https://github.com/arendst/Tasmota/issues/15280)
- ESP32 update the internal Berry type system to sync with Skiars Berry repository. No expected impact on code, but .bec files need to be generated again [#14811](https://github.com/arendst/Tasmota/issues/14811)
- BL0939, BL0940 and BL0942 energy monitoring buffer miscompares resulting in wrong daily energy values regression from v9.5.0.8 [#14829](https://github.com/arendst/Tasmota/issues/14829)
