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 and AWS 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.
- **tasmota-ir.bin** = The InfraRed Receiver and transmitter version allowing all available protocols provided by library IRremoteESP8266 but without most other features.
- **tasmota-minimal.bin** = The Minimal version allows intermediate OTA uploads to support larger versions and does NOT change any persistent parameter. This version **should NOT be used for initial installation**.
Above binaries are also available as gzipped version allowing faster uploads.
The attached binaries can also be downloaded from http://ota.tasmota.com/tasmota/release. The links can be used for OTA upgrades too like ``OtaUrl http://ota.tasmota.com/tasmota/release/tasmota.bin.gz``
- **tasmota32-BG.bin** to **tasmota32-TW.bin** = The Tasmota version in different languages.
- **tasmota32-ir.bin** = The InfraRed Receiver and transmitter version allowing all available protocols provided by library IRremoteESP8266 but without most other features.
- **tasmota32-display.bin** = The Display version without Energy Monitoring but adds display support.
- **tasmota32-webcam.bin** = The Webcam version adds webcam support.
- **tasmota32-bluetooth.bin** = The Bluetooth version adds BLE support.
- **tasmota32-odroidgo.bin** = The Odroid-Go version is specifically tailored to Odroid_go hardware.
- **tasmota32-core2.bin** = The Core2 version is specifically tailored to M5Stack Core2 hardware.
The attached binaries can also be downloaded from http://ota.tasmota.com/tasmota32/release. The links can be used for OTA upgrades too like ``OtaUrl http://ota.tasmota.com/tasmota32/release/tasmota32.bin``
