This update is mandatory for validators and liteservers. Node changelog. Mytonctrl changelog.

If you have several validator nodes, please update them one by one (update, wait for synchronization, move to the next one).

Upgrade rate in mainnet reached 95%, with 67% weight achieved during the first day of upgrade!

Dear validators, thank you for quick update and careful maintenance of your nodes!

Self hosted ton indexer owners and operators
Please note that you must update your node and indexer latest by the end of day 12th of February.

Target versions:
* TON Node v2025.02, github commit 2a68c86
* Mytonctrl v2.4.0, github commit ee82cb6.
* TON indexer v1.1.5, github commit c4510da5

Make sure that you update indexer submodules by issuing: git submodule update --init --recursive,
To check your submodule versions please issue git submodule status --recursive
Taget submodule versions are:

57b0f804cbcf5173f175ac6643256fd768b686dc ton-index-cpp (heads/fix_sharded_block_data)
e1c31967f1b566c87cddb83a6e679cc0df9b719a ton-index-cpp/external/ton (remotes/origin/ton-index-19-dec)
7b0a9b88f0ba5ef6e258b4a4e63cc54629546467 ton-index-go (heads/main)

API interfaces of indexer will retain backward compatibility.

This change is related to archive slices stored in shard-wise format.

Please note that the underlying database structure for ton indexer has undergone significant changes, migrations of your existing database will be performed by the updated index-worker on first start. However, your database will miss some historical information required for new API calls, if you want to load this historical data you can restore latest indexer database backup provided by us under the URL https://dump.ton.org/dumps/index/

Block creation has been suspended on the TON mainnet

The TON Core team is aware of the issue and is working to resolve it.

Block production has been restored

A quick fix was released, and updating only a few master chain validators was sufficient to resume block production.

The incident was related to an error in the processing of the masterchain dispatch queue.

We will release a technical report on the incident shortly.
