Simple Versioned Transaction Support (#2407)

 - client: Add support for multithreading to the rust client: use flag `--multithreaded` ([#2321](https://github.com/coral-xyz/anchor/pull/2321)).
 - client: Add `async_rpc` a method which returns a nonblocking solana rpc client ([2322](https://github.com/coral-xyz/anchor/pull/2322)).
 - avm, cli: Use the `rustls-tls` feature of `reqwest` so that users don't need OpenSSL installed ([#2385](https://github.com/coral-xyz/anchor/pull/2385)).
+- ts: Add `VersionedTransaction` support. Methods in the `Provider` class and `Wallet` interface now use the argument `tx: Transaction | VersionedTransaction` ([2407](https://github.com/coral-xyz/anchor/pull/2407)).
 - cli: Add `--arch sbf` option to compile programs using `cargo build-sbf` ([#2398](https://github.com/coral-xyz/anchor/pull/2398)).
