Wrong returned error
This binary is 100% compatible, the only thing that changed is the returning of a user error message whenever a wrong username is invoked on a transaction. The behavior of the returning sent funds (because the transaction failed) was unaltered in this release.
Mainnet config: https://github.com/multiversx/mx-chain-mainnet-config/releases/tag/v184.108.40.206

We'd like to invite you joining us on Discord, where you can connect with other builders and developers, stay up-to-date on all things happening behind the scenes, and receive support from the community.
PS: Altair is already on testnet. We will publish the documentation altogether with the terms of the "The Great Heist" campaign.
