# Helix 0.115.0: Multi-region support

> Deploy to EU1, AP1, and AP2 regions alongside the existing US1 region, with updated CLI commands and configuration to match.

- Released: 17 Sept 2026 (2026-09-17)
- Packages: @trayai/helix-cli@0.115.0, @trayai/helix-sdk@0.115.0

## Headline changes

### Added: EU1, AP1, and AP2 regions

You can now deploy projects to three new regions - EU1, AP1, and AP2 - in addition to the existing US1 region. Use the `--region` flag or `helix region set <region>` to target a specific region. In `helix.config.ts`, the `env` field has been renamed to `region`, and the default value is now `"us1"` instead of `"production"`. If you previously used `helix env set`, switch to `helix region set`.
