## Preparing for Solana's agave v2.0

Solana is planning a [major release to mainnet-beta](https://github.com/anza-xyz/agave/wiki/Agave-v2.0-Transition-Guide), known as Agave v2.0, in Q4 2024. This release will introduce a number of changes to the Solana network, including modifications to the [Solana RPC](https://www.alchemy.com/dapps/list-of/rpc-node-providers-on-solana) APIs and SDK elements. These changes have already gone live on Devnet and Testnet.

To avoid any issues with your application, we recommend updating your codebase to use the replacement calls listed below as soon as possible.

In this guide, we will summarize methods that will no longer be supported after the latest release and how to prepare for the changes.

**Backwards Compatibility**

All changes are backward compatible and available on previous versions of Solana's mainnet, allowing you to upgrade your applications seamlessly.

## Changes to RPC endpoints and SDK elements
A number of RPC endpoints are being deprecated and no longer supported in Agave v2.0. Please use the replacement calls listed below.
