###### Release mega-20260720


This is a massive release, where quite a lot of ESPEasy has been changed.
The main changes are in the way how networking is handled and support for lots of new Espressif MCU's is added like the ESP32-P4, -C5, C61.

In the start post of [this long 'test build' issue](https://github.com/letscontrolit/ESPEasy/issues/5534) is a lengthy summary of most of the changes.

I would also like to thank all testers for the extremely valuable feedback during the quite lengthy testing process!

###### Backup settings before updating!

**It is strongly adviced to make a backup of the settings of an older ESPEasy node and make sure to have access to the ESPEasy node when updating to this version** as the network settings conversion may not cover 100% of all possible configurations in the field.
Some ESPEasy nodes getting updated to this version may need a power cycle after updating.

### mega-20250430

- Date: 2025-04-30
- Version: mega-20250430

###### Release mega-20250430

**Last ESP32-xx SPIFFS release**

This will be the last release build with SPIFFS for ESP32-xx.  (SPIFFS will remain for ESP8266)
Next official build will be only LittleFS for ESP32-xx.

Only exception may be when some serious bug will be found in this release which forces a new build to be made in the next few days.

This means there needs to be some conversion to be done from SPIFFS to LittleFS on the next release.
We will make sure there is a proper step-by-step process how to convert SPIFFS to LittleFS.


**Workaround for poor WiFi connection after update**


ESP32-xx LittleFS builds in this release are now using ESP-IDF 5.4.1
Espressif made some significant changes in the WiFi code.
This means the existing WiFi RF calibration data may not be compatible with new RF calibration data in ESP-IDF >= 5.4.

If your ESP board shows poor WiFi connection quality, please run the following command either via serial console or the command line field on the Tools page:

```
EraseSDKwifi
```

This will disconnect WiFi and some boards may need a power cycle to get online again.
Please wait at least 10 seconds after entering this command before turning off the device if it doesn't get back online.

Some boards seem to need >1 of such attempts to erase the RF calibration data, due to a bug which may stall the ESP while erasing this data.

N.B. _Not all boards need this, as it only seems to make a really noticable difference on some boards._
