# RELEASE NOTES
2018-08-28 16:34:51 +01:00
## Migration Information
See [wiki migration path ](https://github.com/arendst/Sonoff-Tasmota/wiki/Upgrade#migration-path ) for instructions how to migrate to a major 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**
4. Migrate to **Sonoff-Tasmota 6.x**

## Core version 2.3.0 vs 2.4.2
2019-03-19 14:37:21 +00:00
This release is based on ESP8266/Arduino library core 2.3.0 (again) as some people encountered wifi related issues on core 2.4.2. For others core 2.4.2 is working just fine. Both version are available from http://thehackbox.org/tasmota/release/
2019-05-22 13:56:47 +01:00
## Change in default initial configuration tool
2018-08-29 15:05:27 +01:00
Firmware binary **sonoff-classic.bin** supports **WifiManager, Wps and SmartConfig** for initial configuration. The default tool is **Wps** .
2018-08-28 16:34:51 +01:00
To save memory space all other binaries support **WifiManager only** .
