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:

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

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

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

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

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, AWS IoT and Azure 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.

Provided Binary Downloads

ESP8266 or ESP8285 based

The following binary downloads have been compiled with ESP8266/Arduino library core version 2.7.4.9.

tasmota.bin = The Tasmota version with most drivers for 1M+ flash. RECOMMENDED RELEASE BINARY
tasmota-AF.bin to tasmota-VN.bin = The Tasmota version in different languages for 1M+ flash.
tasmota-lite.bin = The Lite version without most drivers and sensors for 1M+ flash.
tasmota-knx.bin = The Knx version without some features but adds KNX support for 1M+ flash.
tasmota-sensors.bin = The Sensors version adds more useful sensors for 1M+ flash.
tasmota-ir.bin = The InfraRed Receiver and transmitter version allowing all available protocols provided by library IRremoteESP8266 but without most other features for 1M+ flash.
tasmota-display.bin = The Display version without Energy Monitoring but adds display support for 1M+ flash.
tasmota-zbbridge.bin = The dedicated Sonoff Zigbee Bridge version for 2M+ flash.
tasmota-zigbee.bin = The dedicated cc25xx Zigbee Bridge version for 4M+ flash.
tasmota-minimal.bin = The Minimal version allows intermediate OTA uploads to support larger versions and does NOT change any persistent parameter for 1M+ flash. This version should NOT be used for initial installation.

Above binaries are also available as gzipped version allowing faster uploads.
