Changelog

• Separate controller accounts in staking are deprecated. Existing controller accounts will keep working as usual, but new users who join staking will be forced to use a single account for staking (in other words - their stash and controller accounts will be the same account)
• New version of contracts pallet. Smart contracts written in ink! should be compiled with cargo contract version 3.2.0
• Separate port for RPC requests is removed. Now both WebSocket and RPC traffic is handled on the same port
• All Substrate dependencies (including all pallets!) upgraded from version polkadot-v0.9.38 to version polkadot-v1.0.0 (significant API changes! See below)
• Native execution of runtime removed - all execution is handled by the on-chain WASM runtime now
• Changes to internal block sync request mechanism
• (added in 12.1) fixed a bug where the node would sometimes not finalize blocks during a major sync
• (added in 12.1) made it possible to start a node with a DB that contains a lot of non-finalized blocks
• (added in 12.2) To match the previous behavior the seal_balance call in pallet_contracts has been changed to output the balance free to spend instead of just free balance. In particular calling env().balance() on a freshly-instantiated ink! contract returns 0 instead of the existential deposit.

Node upgrade instructions

aleph-node-runner

To accommodate for changes in the aleph-node, the Aleph Node Runner was also significantly changed and improved. To get the newest changes you will need to EITHER:

• do a git pull
• delete the whole repo and git clone it again

In either case, please make sure to back up any configuration changes you made to your setup.

The new node runner will automatically detect the aleph-node version to run, so every time you restart it from now on, it will be on the correct version for the network you're targeting (Testnet or Mainnet).

Building from source

In most cases, the only difference from the usual procedure will be that you will need to modify the environment variables:

• remove WS_PORT and WS_MAX_CONNECTIONS
• set RPC_PORT=9944 and RPC_MAX_CONNECTIONS=100
  See the changelog above if you're running any non-standard config: you might need to change some more variables accordingly.
