## Migration Information
2019-11-13 09:17:52 +00:00
2020-03-29 22:28:41 +01:00
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:
2018-08-28 16:34:51 +01:00
1. Migrate to **Sonoff-Tasmota 3.9.x**
2. Migrate to **Sonoff-Tasmota 4.x**
3. Migrate to **Sonoff-Tasmota 5.14**
2019-11-17 14:38:22 +00:00
4. Migrate to **Sonoff-Tasmota 6.x**
2019-10-27 11:18:47 +00:00
5. Migrate to **Tasmota 7.x**
2019-12-23 16:41:36 +00:00

--- Major change in parameter storage layout ---
2019-12-23 16:41:36 +00:00
2019-12-23 13:05:26 +00:00
6. Migrate to **Tasmota 8.1**
7. Migrate to **Tasmota 8.x**

While fallback or downgrading is common practice it was never supported due to Settings additions or changes in newer releases. Starting with release **v8.1.0 Doris** the Settings are re-allocated in such a way that fallback is only allowed and possible to release **v7.2.0 Constance**. Once at v7.2.0 you're on your own when downgrading even further.

## Supported Core versions
2020-03-23 14:19:08 +00:00
This release will be supported from ESP8266/Arduino library Core version **2.6.3 + e64cb61** due to reported security and stability issues on previous Core version. This will also support gzipped binaries.
2019-11-13 09:17:52 +00:00
Although it might still compile on previous Core versions all support will be removed in the near future.
2019-09-25 14:44:41 +01:00
2019-10-17 17:09:23 +01:00
## Support of TLS
2019-11-13 09:17:52 +00:00
2020-03-29 22:28:41 +01:00
To save resources when TLS is enabled mDNS needs to be disabled. 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)
2019-03-19 14:37:21 +00:00
## Initial configuration tools
2019-11-13 09:17:52 +00:00
For initial configuration this release supports Webserver based **WifiManager** or **Serial** based command interface only. Support for **WPS** and **SmartConfig** has been removed.

- **tasmota-sensors.bin** = The Sensors version adds more useful sensors.
- **tasmota-ir** = The InfraRed Receiver and transmitter version allowing all available protocols provided by library IRremoteESP8266 but without most other features.
- **tasmota-display.bin** = The Display version without Energy Monitoring but adds display support.
- **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**.
