VS Code 1.129.1

I've been running VS Code 1.129 since it dropped earlier this week, and yeah — it's a banger with that new agent host. But you know what's even better? 1.129.1, the patch that landed hot on its heels, fixing rough edges from the big July release.

TL;DR: the agent host is still the star. This patch smooths out the DX considerably. Here's what changed.

What 1.129 Brought

The 1.129 update introduced a dedicated agent host — Copilot-level AI with its own editor panel inside the Agents window. You can now run shell commands directly with ! from the command palette, which is blazing fast. Plus there's a preview of the modern UI refresh that makes everything feel snappier.

1.129.1 Patch Fixes

This patch addresses several regressions reported after 1.129.0 rolled out to the stable channel:

• Agent host stability — No more random crashes during multi-step agent tasks
• UI rendering — The modern UI preview now renders correctly on non-English locales
• Extension compat — Resolved a conflict with popular themes and language packs
• Memory — Reduced memory pressure when the agent host is active and idle

Final Take

If you skipped 1.129.0 because of early-bird bugs, 1.129.1 is your signal to update. The agent host alone is worth the click. Period.
