The Celo Blockchain team is pleased to announce the release of [celo-blockchain v1.2.5](https://github.com/celo-org/celo-blockchain/releases/tag/v1.2.5).

v1.2.5 contains a single feature that substantially improves performance around transaction pool management. This will facilitate, subject to on-chain governance, an increase in the network’s transaction throughput by raising the block gas limit.

We strongly recommend all validator operators upgrade as soon as possible – primarily on validator instances – first on baklava, then on mainnet.

Validator proxies and full nodes may be upgraded, but it is not essential that they are.

cLabs plans to ask validators to [support a governance proposal](https://forum.celo.org/t/a-surge-in-users-calling-all-validators-to-accelerate-blockchain-throughput/883) as early as Tuesday 6th April to increase the block gas limit, which will depend on most validators running this version.

Please reach out here or on [Discord](https://chat.celo.org/) if you have any questions, suggestions, or need support.

Best,

cLabs Team
