CMS_BREAK -->

## Highlights

### Segment plugin update: Typescript support and Subscribers API

Landed in #5904.

### SendGrid plugin update: Custom templates support

Landed in #5833.

### Axios adapter support in `@medusajs/medusa-js`

### API Routes for Medusa v2

Core API Routes (located in `packages/medusa/src/api`) are not registered when Medusa v2 feature flag is enabled.

And to repeat, all changes behind Medusa v2 are very unstable, highly experimental, and a work in progress at this point, so we do not encourage the use of the feature flag yet.

Follow our development toward Medusa v2 in [our roadmap](https://github.com/orgs/medusajs/projects/7).
