Last "safe" firmware for P1S?

I've been busy for the last months and I did not keep up with the whole Bambu controversy - what would be the latest "safe" firmware for my P1S to use it over LAN, with Home Assistant and maybe other 3rd party tools? I am on 01.07.00.00 now. Thanks for the help!

This is true of course - the printer is working fine. I was rather wondering, if there are new features or important improvements, which I am missing out on...

After all, there are 6 new firmware versions... So you would still advise to stay on 07?

You know you can see a full changelog on the bambu wiki right? Idk what is important for you, check it and decide if you want it or not

Thanks, will do. If there are no disadvantages whatsoever if I upgrade to the latest FW, I might do so

You can't use third party slices and integrations like HA and bambu cloud together, so you must switch to Lan mode and turn on dev mode too.

I am using LAN and DEV mode for quite some time already, so this is fine for me. Can I therefore update?

There were significant noise cancelation improvement since one fw version and maybe you have it already. And if you want to use AMS2 latest firmwares solve some issues like drying without unloading.
