Solana Labs has published version 1.18.26 of its core software, marking a stable release intended for use on the Mainnet Beta network. The update focuses on improving the reliability of validator nodes by ensuring that the ContactInfo.outset data is refreshed before the validator component is initialized.
The change was introduced by contributor @behzadnouri in pull request #3135. By refreshing ContactInfo.outset early, the software reduces the risk of stale or incomplete contact information affecting node connectivity during startup. This adjustment is expected to enhance the overall robustness of the network, especially for operators running long‑running validator instances.
While the release is labeled stable, it is still recommended that operators test the update in a staging environment before deploying to production. Solana Labs encourages community members to review the release notes and the underlying pull request for detailed technical context.
The v1.18.26 update is part of Solana’s ongoing effort to maintain a secure and efficient mainnet. By addressing subtle initialization issues, the team aims to provide a smoother experience for validators and reduce potential downtime.
Operators can download the new release from the Solana GitHub repository and follow the standard upgrade procedures. The release is available under the Apache 2.0 license, consistent with Solana’s open‑source policy.
