# Chainstack Self-Hosted v2.59.0: August 24, 2026

> Solana joins the deployment catalog on mainnet and devnet, alongside reliability fixes for OP-Stack and Ronin Saigon nodes.

## Solana support

Solana is now available in the new-node flow, on both mainnet and devnet, running on the agave client. See [Supported clients and protocols](/docs/self-hosted/supported-clients-and-protocols) for the full deployment catalog.

## Reliability fixes

* OP-Stack execution clients — transaction pool admission no longer depends on the sequencer HTTP endpoint being reachable
* Ronin Saigon — the execution client now gets a trusted peer, removing a source of sync stalls
