Wrong information on README? (It *is* working with EVO 7.50+)
## Alarm system
**EVO 192 256K (DIGIPLEX)**
Firmware 7.52.001
Bootloader 1.00.015

**IP150**
Firmware 1.34.000
Bootloader 2.12.001

**BabyWare 5.4.26**
_Information from In-Field Paradox Upgrade Software._

## Describe the bug
The README of project warns:

**Do not upgrade EVO firmware versions to 7.50.000+. Process is irreversible! Paradox introduces serial communication encryption which most probably will break our PAI ability to talk to the panel.**

However, I got myself a new EVO 192 panel which came with 7.52.001. **And PAI is working fine with it.** (I'm using via home assistant).

Has anybody more information about this? It seems clearly misleading or incomplete. 

What I discovered, so far:

The [firmware changelog](https://www.paradox.com/DotNetApp/FirmwareUpdate/FirmwareUpdate.aspx?SUBCATID=68&group_id=5) available on paradox site indeed says:

```
V7.50.011(released on April 21, 2021)
Firmware Download
V7.50.011

What's new
- Added serial port encryption - the serial output will be operational only with Paradox devices (IP150/+, PCS250/260/265/265LTE, USB307)
- Added serial port unlock license key for 3rd party communication devices ( license can be purchased from Insite Gold Installer Menu)
- The unlock license key needs to be entered in keypad programming only, section 3000 – (Only TM50/TM70 keypads can be used - A-Z characters needed)
- Panel programming is compatible with BabyWare 5.4.26 version and up
- This firmware version cannot be downgraded
```

But, as I said, it is working. 

Maybe it is working because my IP150 is running a VERY old firmware version? (pre-2016)

Sadly, the [IP150 firmware changelog](https://www.paradox.com/DotNetApp/FirmwareUpdate/FirmwareUpdate.aspx?SUBCATID=38&group_id=64) doesn't mention anything about cryptographic communications. So, I don't know what would be a "safe" version to upgrade it.

I'm using it on a test panel (not in production) with almost all default values (did a hard reset) except for users/zones/areas.
