These additions aim to reduce dependencies and surface vulnerabilities before install.

PostMessage 500x Gains Come With Conditions
Bun achieved a 500x postMessage speedup by avoiding serialization in certain cases.
The dramatic win applies only under specific conditions where payloads don't require serialization.

Use OS Native Secret Storage
Store CLI secrets using the OS native credential manager to avoid plaintext files.
Let Bun use Keychain or Windows credential storage for safer local secret handling.

Last episode, we lamented Claude’s lack of checkpoints to roll back code when it goes off the rails. Other devs feel the same, and this week Checkpoints for Claude Code debuted. It’s an MCP server that follows Claude Code, creating checkpoints when tasks are completed, allowing for easy reverts when needed.
The Bun team quietly pushed some nice new features in Bun v1.2. Highlights include: a unified SQL client with zero dependencies, native YAML file support, OS native credential storage for secrets, and a security scanner API that scans packages for vulnerabilities before installation.
And MCP-UI, a toolkit of interactive UI components for MCP has new features to support resources beyond text like embedded iframes and even raw HTML. Not all agents with MCP support can handle these new resources, but if they can, users can see product photos, data visualizations, and other mini sites right in their AI chat.
In the Lightning News section for this week, the folks at Deno leading the charge to get Oracle to relinquish its trademark for JavaScript need our help. Those legal bills aren’t going to pay themselves and Deno’s pockets aren’t nearly as deep as Oracle’s, so if you care about making JavaScript public domain (which it absolutely should be), please consider donating so they can keep fighting the good fight to free JS. Every little bit helps.
