Upgrading

Upgrading from 0.2.0

There are no breaking changes from 0.2.0, only new functionality for Token-2022.

Upgrading from 0.1.x

When upgrading from spl-token 0.1.x, you may see the following error in your code:

import {TOKEN_PROGRAM_ID, Token, AccountLayout} from '@solana/spl-token';
                          ^^^^^
SyntaxError: The requested module '@solana/spl-token' does not provide an export named 'Token'

The @solana/spl-token library as of version 0.2.0 does not have the Token class. Instead the actions are split up and exported separately.

To use the old version, install it with:

npm install @solana/spl-token@0.1.8

Otherwise you can find documentation on how to use new versions on the SPL docs or Solana Cookbook.
