⚠️ Dear validators! Please update your nodes!

Node: (https://github.com/tonlabs/ton-labs-node) 0.50.4 - 837a68e9e866b74302ab01179f75ae4e4b372e58
Tools: (https://github.com/tonlabs/ton-labs-node-tools) 0.1.261 - d4e804d6e2d540e7d6059218d57e9d26dedb03b0

Dear Validators!

📢 We would like to inform you that additional stakes in DePools made in March will be withdrawn in the next few cycles. They have served their purpose and are no longer needed.

✌️ A substantial decrease in the total stake in elections will have a positive effect on the profitability of validation.

Great news for all Staking addicted! The annual staking yield increased twice and went as high as 12%. That also means that participants of the first Boosted Staking program now earn up to 27% APR in EVER!

🏄‍♂️

📢 Dear Developers and Partners!

We are ready to enable new TVM instructions in Everscale Main Net.

‼️This update will lead to a BREAKING CHANGE in account format which may cause your nodes to stop working. ‼️

To avoid such problems - you need to UPDATE your DApp Servers and Validator Nodes to the latest version:

✅ DApp server ≥0.1.5 version - https://github.com/tonlabs/evernode-ds/releases
✅ Validator Node - latest master commit https://github.com/tonlabs/ton-labs-node

At the moment we support both Account format versions in Public API and in DApp Server API so that applications can smoothly migrate to the new account version. To do it just update SDK to the latest version (≥1.31.0). If you work with API directly, enable the new http header. We encourage you to do it ASAP because we will support both account formats temporarily.

📢 Attention to all Everscale developers!

‼️This is a scheduled friendly reminder that net*.ton.dev and main*.ton.dev endpoints will be switched off on 16th of May. Please migrate your application to the new endpoints. ‼️

Deprecation schedule:
https://tonlabs.gitbook.io/evernode-platform/reference/breaking-changes/deprecation-schedule

You can find the actual list of public endpoints in the documentation
https://tonlabs.gitbook.io/evernode-platform/products/cloud/public-api

🔥ATTENTION, ATTENTION, ATTENTION ALL VALIDATORS‼️

Details:

We are continuing to improve the Everscale Node. Mostly all efforts were focused on creating better performance and stability of the node.

In terms of stability, a couple of security fixes were made to prevent accidental node reboot and a blockhain freeze. Additionally, node DB stability was improved.

In terms of performance, advanced approaches were implemented to speed up node calculations over accounts with huge sizes of data. New features are mostly related to the support of new VM assembly commands in smart contracts. Additionally, a traffic compression feature was implemented to allow optimization of network bandwidth utilization.

What do I need to do?

Please update your nodes to the special version ASAP. In order to do this please write to @Custler NOW and he will give you special instructions. Thank you.

Please hurry!

🚀 Subscriptions backend redesigned 🚀

Many of you reported us feedback about poor websocket subscriptions quality: frequent websocket reconnections, missed data, stalling and so on.

We invested significant amount of time in the complete redesign of the subscriptions backend and deployed it to production 2 weeks ago. Some of our clients have already made tests on their side and confirmed that no reconnects and no data loses occur any more.

You don't need to migrate to the new subscriptions. If you are using subscriptions now, they already work on the new backend!

If you used 'pull' approach because of subscriptions unreliability,
now you can switch to websockets and become more real-time and responsive to your users.

Thank you for your feedback and we are happy to hear more of it to improve and give you better service. ❤️

Deleted accounts available in Evernode Public API

Many of you requested us to see the deleted accounts in Cloud public API.

We added this feature and also processed all the transaction history to recover old deleted accounts.

All the deleted accounts are now available in API and [https://ever.live/](https://ever.live/landing)

Thank you for your feedback and if you have any please leave it in channels or Everscale telegram channel

​​Maintenance underway on Everscale mainnet

The mainnet is experiencing some difficulties due to transition to one shard. Maintenance is currently ongoing, and the problem should be fixed in a couple of hours.

#Maintenance

Dear Evernode Cloud users!
Mainnet Cloud is fixed.

We have fixed the bug with empty cell parsing that returned incorrect value for { shard_hashes { shard }} in case of p12.min_split = 0. Now API is fully functional.

Community-driven development 💬

Dear Everscale developers and Evernode Platform users,
we have a big announcement for you today!

For over two years the Evernode Platform team has been developing its products based on the requirements of the ecosystem and the wishes of the the community.

Up until now the community feedback was collected in Telegram channels and personal conversations with developers. The Evernode Platform roadmap was published on our website in January 2022.

Now we want to bring our communication with the community to the next level.

We changed the structure of our website to better reflect community-driven approach and turned the roadmap into a more convenient kanban board.

We also added a way to submit your ideas, vote for and comment on the ideas of others.

Links to the roadmap and the ideas page are now in the header of the website.

Our website: https://docs.everos.dev/evernode-platform/

Thank you for choosing Evernode Platform.
