**Runtime release notification**

Hello,

This is to advise you that the Polkadot community is currently voting to upgrade the [_Polkadot system_](https://polkadot.subsquare.io/referenda/1828) to the [v2.0.5 release](https://github.com/polkadot-fellows/runtimes/releases/tag/v2.0.5).

This is a major runtime upgrade that enables [_Revive_](https://docs.polkadot.com/develop/smart-contracts/), a smart contract platform that can execute PVM and EVM contracts which are fully interoperable.

🚧 **Important note for Ecosystem builders:** 🚧  
We have made some necessary changes to the EVM gas model to account for the faster instruction processing that will be enabled by PolkaVM Just In Time compile (aka PolkaVM JIT) in the future. This means that a small fraction of existing Solidity contracts cannot be deployed unchanged, but developers can keep using familiar Ethereum tooling, such as Foundry and Hardhat.

**Additional notes for Ecosystem builders:**  
This release enables Elastic Scaling on Polkadot Hub to allow higher throughput and prepare the chain to switch from a 6-second to a 2-second block time shortly after enactment.  
You can find more details about this change [here](https://github.com/polkadot-fellows/runtimes/pull/1048).

This release also introduces the “Hard Pressure” issuance model which caps the total supply of DOT at 2.1 billion by 2061. This is a new model for inflation that will take effect on 14th March 2026.  
You can find more details about this change [here](https://github.com/polkadot-fellows/runtimes/pull/898).

The projected enactment date for this runtime upgrade is 27th January 2026.

Many thanks.
