0.30.2

0.30.2 adds TypeScript client support for parsing Solana transaction version 1 (v1) transactions. This is a TypeScript-only patch release.

How to upgrade

1. Update anchor-cli:

   avm install 0.30.2

2. Update Anchor crate(s) to 0.30.2.

3. Replace the legacy @coral-xyz/anchor and related @coral-xyz/* packages with @anchor-lang/core:

   npm install @anchor-lang/core

   Update imports accordingly:

   // Before
   import * as anchor from "@coral-xyz/anchor";
    
   // After
   import * as anchor from "@anchor-lang/core";

Recommended Solana Version

This release supports any Solana version above 1.17.3, with 1.18.17 recommended. Upgrade Solana tools with:

solana-install init 1.18.17

TypeScript

Solana transaction version 1

AnchorProvider can now deserialize and process Solana v1 transactions. When a transaction fails, Anchor also retrieves the transaction with maxSupportedTransactionVersion set to 1, so the client can return the program logs instead of failing while parsing the response.

The client now uses @solana/web3.js 1.99.0 and requires Node.js 20.18.0 or later.

TypeScript package migration

Users must switch from the legacy @coral-xyz/anchor packages to @anchor-lang/core. Update both the package dependency and all imports; the legacy package line is not the supported path for this release.
