Upgrade notes

No breaking changes to node.toml config for v0.15.2.
Page-encoded timeline supportv0.15.2 introduces dual-timeline storage. Every node will eventually activate and populate a secondary page-encoded timeline. This is a one-time procedure requiring approximately 8 minutes offline per node. See MIP-8 Activation and Page Storage Migration for details.PLEASE WAIT FOR OFFICIAL ANNOUNCEMENT BEFORE RUNNING THE PHASE-A MIGRATION
eth_call revert error code changed. eth_call execution revert error code changed from -32603 to 3. If your integration checks for -32603 on reverts, update to expect 3.
Optional: If you previously used --prometheus-addr or related CLI flags on monad-bft, these are now configured in the [prometheus] section of node.toml. Remove the CLI flag and add:
Note: If you have a custom full_node_raptorcast.round_span value in node.toml, verify it is ≤ 960. Values above this cap are now rejected at startup.
monad-sign-name-record flag change. The --address ip:port flag has been replaced with separate --ip, --tcp-port, and --udp-port flags. Update any scripts that call monad-sign-name-record.

​
1. SSH into the node as root user

​
2. Stop services

​
3. Upgrade monad package

If you encounter issues with the GPG signature (e.g. signatures were invalid), please renew the keys with the command below.
The apt-mark hold monad command prevents the monad package from being upgraded automatically by apt-get upgrade. Without it, unattended system upgrades can install a newer version of monad that has not been approved for your network, causing version mismatch issues.

​
4. Start services and verify

All services should show Active: active (running). Confirm the node rejoins and advances blocks.

​
5. Verify the correct version is running

Expected output:
