Sonoff-Tasmota v6.6.0

RELEASE NOTES

Migration Information

See wiki 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

Support of TLS

TLS support for core 2.3.0 is removed.

TLS is supported on core 2.4.2 and up. 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. See full documentation on https://github.com/arendst/Sonoff-Tasmota/wiki/AWS-IoT

Core version 2.3.0 vs 2.4.2 vs 2.5.2

This release is based on ESP8266/Arduino library core 2.3.0 as some people encountered wifi related issues on core 2.4.2 and 2.5.2. For others core 2.4.2 or 2.5.2 is working just fine. All version are available from http://thehackbox.org/tasmota/release/

Change in default initial configuration tool

Firmware binary sonoff-classic.bin supports WifiManager, Wps and SmartConfig for initial configuration. The default tool is Wps.

To save memory space all other binaries support WifiManager only.
