RELEASE NOTES

Migration Information

This version removes support for direct migration from versions before v8.1.0 (Doris)

See migration path for instructions how to migrate to a major version. Pay attention to the following version breaks due to dynamic settings updates:

1. Migrate to Sonoff-Tasmota 3.9.x
2. Migrate to Sonoff-Tasmota 4.x
3. Migrate to Sonoff-Tasmota 5.14
4. Migrate to Sonoff-Tasmota 6.7.1 (http://ota.tasmota.com/tasmota/release-6.7.1/)
5. Migrate to Tasmota 7.2.0 (http://ota.tasmota.com/tasmota/release-7.2.0/)

--- Major change in parameter storage layout ---

6. Migrate to Tasmota 8.5.1 (http://ota.tasmota.com/tasmota/release-8.5.1/)

--- Major change in internal GPIO function representation ---

7. Migrate to Tasmota 9.1 (http://ota.tasmota.com/tasmota/release-9.1.0/)

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.

Supported Core versions

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.

Support of Core versions before 2.7.1 has been removed.

Support of TLS

In addition to TLS using fingerprints now also user supplied CA certs and AWS IoT is supported. Read full documentation

Initial configuration tools

For initial configuration this release supports Webserver based WifiManager or Serial based command interface only. Support for WPS and SmartConfig has been removed.
