Heap Space
Has this build changed? when I run the basic example after a period of time there is a stack overflow and the ESP crashes. I have added to the example to return free heap, when I run this from telegram client on my phone I can see the heap keeps reducing until the ESP crashes. The following hardware is a Nodemcu V3 Any fixes for this?
Cheers

// Code added to return heap free size from bot.
if (text == "/tech") { int StrHeap = (ESP.getFreeHeap()); String msg = "Dans Node IOT Statistics.\n"; msg += String(ssid) +" : " + String(WiFi.RSSI()) + " dBm\n"; msg += "IP address : " + WiFi.localIP().toString() + "\n"; //msg += "Vcc : " + String(ESP.getVcc()) + " mV\n"; msg += "Bell Counter : " + String(kCounter) + "\n"; msg += "uptime : " + String(millis()/(10006060)) + " h\n\n"; msg += "You are Registered!\n"; msg += "This Chat ID is : " + chat_id + "\n"; msg += "Free Heap Space : " + String(StrHeap) + "\n"; bot.sendMessage(chat_id, msg, "");
}
Debug console output when crash occurs.

damn it .. I've got the same issue but one year later. And even on this post no one ever replied.. I was logging free heap bytes when I recognized it shrinks everytime I use bot.getUpdates . Interestingly even on bot.sendMessage it shrinks for a short time and then after a minute it frees some bytes again.
Honestly, the library is inefficient from a heap perspective.
If I was doing the library again now I would not use String anywhere, but I didn't really know what I was doing back then (and I still don't). I do not have time for a major re write at the moment.
Something like this is implemented much more efficiently from a heap perspective

Also the above sample of code is also very inefficient from a heap perspective, concatenating strings is the devil , reducing the amount of that in the sketch will improve your heaps chances.
Reserving space up front might also help
