## Highlights

### Jito Bundle Support

Submit up to 5 transactions atomically via Jito's block engine. New RPC methods:

- [`signBundle`](/docs/tools/kora/beta/bundle-methods#signbundle) — Sign a
  bundle without broadcasting
- [`signAndSendBundle`](/docs/tools/kora/beta/bundle-methods#signandsendbundle)
  — Sign and submit to Jito
- [`estimateBundleFee`](/docs/tools/kora/beta/bundle-methods#estimatebundlefee)
  — Estimate total bundle fees

See the [Jito Bundle Guide](/docs/tools/kora/beta/jito-guide) for a full
walkthrough.

### Docker Images

Official multi-platform images (amd64/arm64) published to GitHub Container
Registry. See [Installation](/docs/tools/kora/beta/installation).

### Transaction Plugins

A new plugin system allows Kora to validate transaction shapes during signing
flows. The first built-in plugin, `gas_swap`, enforces strict rules for gasless
token-for-SOL swap transactions. Plugins are configured in `kora.toml` and run
automatically during `signTransaction`, `signAndSendTransaction`, `signBundle`,
and `signAndSendBundle`.

See
[Configuration — Transaction Plugins](/docs/tools/kora/beta/configuration#transaction-plugins).

### New Configuration Options

- **Transaction Plugins** for transaction shape validation (`gas_swap`)
- **reCAPTCHA v3** bot protection for signing endpoints
- **Lighthouse** fee payer drainage protection
- **Usage Limits** per-wallet transaction limiting
- **Bundle configuration** for Jito integration

See [Configuration](/docs/tools/kora/beta/configuration).

### SDK Changes

- Bundle method support (`signBundle`, `signAndSendBundle`, `estimateBundleFee`)

See [SDK Changes](/docs/tools/kora/beta/sdk-changes).

### Additional RPC Methods

- [`getVersion`](/docs/tools/kora/beta/bundle-methods#getversion) — Retrieve
  server version information
