 ### Breaking
 - In [#1387](https://github.com/entropyxyz/entropy-core/pull/1387/) the substrate version was updated, this could cause changes to the chainspec file as well requires a strategy for command line argument ```--public-addr``` and for handling ```node-key-generation```
+- In [1436](https://github.com/entropyxyz/entropy-core/pull/1436) rust is downgraded to version 1.86
