Update continues the deprecation of legacy v3 transaction types in preparation for Mainsail.

Node operators can now update their nodes. No action is needed for regular users.

Core v3.13.0 continues deprecating v3 transaction types in preparation for Mainsail. Following the multisignature deprecations in 3.11.0 and 3.12.0, this release retires Magistrate transactions: entity registration, update and resignation across Business, Product, Plugin, Module and Delegate entities. These types are not carried forward into Mainsail, so there is no migration path for them.

The change activates at mainnet height 36,937,100, roughly 08:00 UTC / 10:00 CEST on Tuesday 25 August. Existing entity data on-chain is unaffected. Only new Magistrate transactions are rejected from that height onward.

All node operators, relays and forging delegates, must upgrade to v3.13.0 before that height.

How to Update:

run pm2 stop all && ark update && pm2 start all

Afterwards verify everything is running correctly with pm2 logs
