Oasis Core 22.2.7 Testnet announcement

From Discord, posted by @jernej
We have released Oasis Core 22.2.7 for TESTNET . This release moves the halt epoch configuration to be per-node (previously it was defined in the genesis file), defaulting to it being disabled. The upgrade is non-breaking and can be performed at any time by replacing the oasis-node binary and restarting your node. All node operators on TESTNET are encouraged to upgrade. For more information and links to releases see the updated TESTNET network parameters (https://docs.oais.io/node/testnet/). Thanks!
