Updating firmware to 3.2.3 -> 3.5, FW update process in general

[MEKadan]

I apologize, if this text goes to somewhat wrong place, but I could not find a better one, not least because of the fact that I'm quite unexperienced Github user and not a sw professional. Last time working with Heishamon installation was some time ago, and I cannot remember what was done then.

My question is about installing new firmware. The Readme does not contain very detailed instructions on updating FW

First of all, I got the following message in Home Assistant:

After exploring a while, I ended up in https://github.com/Egyras/HeishaMon/tree/master/binaries

If I am not mistaken, I should pick up a suitable binary file, which I suspect is the HeishaMon.ino.d1-v3.5.bin and install it via Heishamon WebUI.

The file (3.5) is in the mode-type-small folder, however, I cannot find the corresponding md5?

The Readme in binaries -folder talks about "The LittleFS versions" Is this the same than mode-type-small?

Then, the Readme syas: "The LittleFS versions will, after updating to this version, reset your HeishaMon to factory default due to change to a new filesystem for the configuration."

Is it enough to restore my original configuration just by copying all the parameters from the Settings -page of the WebUI?
