# RELEASE NOTES
2018-08-28 16:34:51 +01:00
## Migration Information
2019-11-13 09:17:52 +00:00
2021-02-12 14:02:55 +00:00
**This version removes support for direct migration from versions before v8.1.0 (Doris)**
2021-02-10 13:45:57 +00:00
2022-02-07 14:13:16 +00:00
See [migration path ](https://tasmota.github.io/docs/Upgrading#migration-path ) for instructions how to migrate to a major version.
2018-08-28 16:34:51 +01:00
2021-10-25 19:44:16 +01:00
**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.
2022-02-07 14:13:16 +00:00
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**
2022-08-31 14:51:21 +01:00
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
2022-02-12 17:27:01 +00:00
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)
2019-12-23 16:41:36 +00:00
2019-12-23 13:05:26 +00:00
--- Major change in parameter storage layout ---
2019-12-23 16:41:36 +00:00
2022-02-12 17:27:01 +00:00
6. Migrate to **Tasmota 8.5.1** (http://ota.tasmota.com/tasmota/release-8.5.1/tasmota.bin)
2019-12-20 15:22:49 +00:00
2020-10-03 11:08:43 +01:00
--- Major change in internal GPIO function representation ---
2020-09-30 14:44:37 +01:00
2022-02-12 17:27:01 +00:00
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)
2020-09-30 14:44:37 +01:00
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** .
