Release v1.18.25

This is a stable release suitable for use on Mainnet Beta.

Note: solana-install no longer supports channel names (edge, beta, stable). It still works with explicit version numbers like this: solana-install init v1.18.25. agave-install is the maintained fork; it supports channel names and explicit version numbers.

All v1.18 releases will be available from both this repo and Agave. After v1.18 this repo will be archived. More information about migrating to Agave is available here:
