Minor Changes

• #12826 de65c58 Thanks @gabivlj! - Enable container egress interception in local dev without the experimental compatibility flag

  Container local development now always prepares the egress interceptor sidecar image needed for interceptOutboundHttp(). This makes container-to-Worker interception available by default in Wrangler, Miniflare, and the Cloudflare Vite plugin.

• #12754 e4d9510 Thanks @emily-shen! - Add cross-process support to the local explorer

  When running multiple miniflare processes, the local explorer will now be able to view and edit resources that are bound to workers in other miniflare instances.

Patch Changes

• #12790 5451a7f Thanks @petebacondarwin! - Bump hono to ^4.12.5 and devalue to ^5.6.3 to address security vulnerabilities

  Hono had multiple advisories including arbitrary file access via serveStatic, JWT algorithm confusion, and XSS through ErrorBoundary. Devalue had denial of service vulnerabilities in devalue.parse. These are bundled dependencies so the fix is delivered via this patch.
