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. 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** (http://ota.tasmota.com/tasmota/release_5.14.0/sonoff.bin) - NOTICE underscore as a dash is not supported in older versions 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) --- Major change in parameter storage layout --- 6. Migrate to **Tasmota 8.5.1** (http://ota.tasmota.com/tasmota/release-8.5.1/tasmota.bin) --- Major change in internal GPIO function representation --- 7. Migrate to **Tasmota 9.1** (http://ota.tasmota.com/tasmota/release-9.1.0/tasmota.bin.gz) 8. Upgrade to **latest release** (http://ota.tasmota.com/tasmota/release/tasmota.bin.gz) 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 **2.7.8** due to reported security and stability issues on previous Core version. This will also support gzipped binaries. This release will be supported from ESP32/Arduino library Core version **v3.3.8**. Support of ESP8266 Core versions before 2.7.8 and ESP32 Core versions before v3.3.8 have been removed. ##### Initial configuration tools For initial configuration this release supports Webserver based **WifiManager** or **Serial** based command interface. ##### Initial installation Easy initial installation of Tasmota can be performed using the [Tasmota WebInstaller](https://tasmota.github.io/install/). ##### Provided Binary Downloads ###### ESP8266 or ESP8285 based The following binary downloads have been compiled with ESP8266/Arduino library core version **2.7.8**. - **tasmota.bin** = The Tasmota version with most drivers for 1M+ flash. **RECOMMENDED RELEASE BINARY** - **tasmota-4M.bin** = The Tasmota version with most drivers and filesystem for 4M+ flash. - **tasmota-AD.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 _[Truncated at 4000 characters — full notes: https://github.com/arendst/Tasmota/releases/tag/v15.5.0]_ ### v15.4.0 — Tasmota v15.4.0 Sybil - Date: 2026-04-22 - Version: v15.4.0 - Original notes: https://github.com/arendst/Tasmota/releases/tag/v15.4.0 - Permalink: https://whatsnew.fyi/product/tasmota/releases/v15.4.0 - **removed** — Remove support for direct migration from versions before v8.1.0 (Doris) - **changed** — Require ESP8266/Arduino library Core version 2.7.8 or later due to reported security and stability issues - **changed** — Require ESP32/Arduino library Core version v3.1.11 or later - **removed** — Remove support for ESP8266 Core versions before 2.7.8 - **removed** — Remove support for ESP32 Core versions before v3.1.11 Logo #### RELEASE NOTES ##### Migration Information **This version removes support for direct migration from versions before v8.1.0 (Doris)** See [migration path](https://tasmota.github.io/docs/Upgrading#migration-path) for instructions how to migrate to a major version. **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. 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** (http://ota.tasmota.com/tasmota/release_5.14.0/sonoff.bin) - NOTICE underscore as a dash is not supported in older versions 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) --- Major change in parameter storage layout --- 6. Migrate to **Tasmota 8.5.1** (http://ota.tasmota.com/tasmota/release-8.5.1/tasmota.bin) --- Major change in internal GPIO function representation --- 7. Migrate to **Tasmota 9.1** (http://ota.tasmota.com/tasmota/release-9.1.0/tasmota.bin.gz) 8. Upgrade to **latest release** (http://ota.tasmota.com/tasmota/release/tasmota.bin.gz) 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 **2.7.8** due to reported security and stability issues on previous Core version. This will also support gzipped binaries. This release will be supported from ESP32/Arduino library Core version **v3.1.1.250203**.
