Mainnet Validator Software Update [v2026.04-1]

Please update your node software:

Update with mytonctrl:
update master
upgrade master

Target versions:
— mytonctrl: 62bbe8f
— node 591b34d

If you are not using mytonctrl or using ubuntu older than 22.04, check this instruction (https://telegra.ph/TON-Node-Upgrade-202511-11-05).

If you have several validators, please update them one by one:
update a validator => wait for synchronization => move to the next one validator


Update is mandatory for validators and contains measures to improve stability and security of validators.

It is not required, but highly recommended for liteservers and archive liteservers especially those that experienced synchronization instability.


This release does not include breaking API changes and is fully compatible with recent versions of ton-http-api (acceptable versions: v2.0.64 and higher) and TON Indexer (acceptable versions: v1.2.6 and higher).
