@solana/web3.js 3.2.1 on Node.js NPM

pnpm add @solana/web3.js@3.2.1 @solana/wallet-adapter@3.2.1

Highlights

stackHeight on inner instructions: CompiledInnerInstruction.instructions elements now declare stackHeight?: number. The RPC already returned the field, so callers no longer need a cast to read it. (#4049)
```
const tx = await connection.getTransaction(sig, {maxSupportedTransactionVersion: 0});
tx?.meta?.innerInstructions?.[0].instructions[0].stackHeight; // number | undefined
```

Breaking change in a patch release

getTransactionsForAddress no longer accepts encoding: 'base58'. We are shipping it as a patch because:

The method and the option both arrived in 3.2.0 four days ago, so very few projects are using this already.
Agave already rejects base58 when maxSupportedTransactionVersion is 1 or higher. base64 carries the same bytes at a lower cost.

Removing it now keeps new code on base64 and makes a later move to v1 transactions easier.

 await connection.getTransactionsForAddress(address, {
   transactionDetails: 'full',
-  encoding: 'base58',
+  encoding: 'base64',
 });

Maintenance (dependencies, CI, docs)

Security and dependency updates

Bump the minor-and-patch dev dependency group: oxfmt, oxlint, playwright, rollup, next, mocha, @types/* (#4043)
Bump the minor-and-patch dev dependency group: oxfmt, oxlint, playwright, vite, rolldown, rollup; dedupe @babel/runtime (#4047)

CI and tooling

Preview release notes before publish approval (#4042)
- Type declarations are now bundled with Rolldown instead of Rollup. lib/index.d.ts has the same 402 exports, with the same names and targets, as before. The only differences are formatting and three dropped file-header comments. (#4051)
