miniflare@4.20260507.0

Minor Changes

• #13836 039bada Thanks @Skye-31! - Support named recipients in the Email Sending API MessageBuilder

  The send_email binding's MessageBuilder now accepts EmailAddress objects for to, cc, and bcc in addition to plain strings. You can mix named and plain addresses in the same array:

  await env.SEND_EMAIL.send({
    from: "sender@example.com",
    to: [
      "plain@example.com",
      '"Name" <address@example.com>',
      { name: "Jane Doe", email: "jane@example.com" },
    ],
    cc: [{ name: "CC Person", email: "cc@example.com" }],
    subject: "Hello",
    text: "...",
  });

  Additionally, addresses in "Name" <address> format are now correctly parsed when checking allowed_destination_addresses and allowed_sender_addresses restrictions.

• #13776 1a54ac5 Thanks @petebacondarwin! - Default the workerd runtime subprocess to TZ=UTC to match the production Cloudflare runtime

  Previously, Miniflare inherited the host machine's timezone, so Date and Intl APIs inside a Worker observed the developer's local timezone during local development but UTC in production. This caused dev/prod drift that was hard to debug.

  Miniflare now sets TZ=UTC on the spawned workerd subprocess by default. A new unsafeRuntimeEnv option (a Record<string, string>) is available on the Miniflare constructor for advanced cases that need to override the default — for example, to test timezone-dependent behaviour:

  new Miniflare({
    modules: true,
    script: "...",
    unsafeRuntimeEnv: { TZ: "Europe/London" },
  });

Minor Changes

• #13055 f3fed88 Thanks @GregBrimble! - Introducing the cache configuration option for Workers.

  You can now set { cache: { enabled: true } } in your Wrangler configuration file to enable a HTTP cache in front of your Worker's fetch handler. This is also supported in [previews] configuration — previews.cache overrides the top-level cache setting for preview deployments, and falls back to the top-level value when absent. More information can be found in our documentation.

• #13776 1a54ac5 Thanks @petebacondarwin! - wrangler dev and other Miniflare-backed commands now run the local workerd runtime with TZ=UTC to match production

  Previously, wrangler dev (and other commands that spin up Miniflare, such as wrangler kv, wrangler d1, wrangler r2, wrangler check) inherited the host machine's timezone, so Date and Intl APIs inside a Worker observed the developer's local timezone during local development but UTC in production. This caused subtle, hard-to-debug differences between local and deployed behaviour.

  Local development now matches production. Code that previously relied on the host timezone during wrangler dev will need to either accept UTC (the production behaviour) or explicitly construct dates/formatters with the desired timezone.

• #13777 18e833d Thanks @matingathani! - fix: throw a clear error when _routes.json contains invalid JSON instead of silently skipping it

• #13751 b6cea17 Thanks @matingathani! - fix: ensure wrangler types --check --env-file does not falsely report stale types when .dev.vars exists

• #13775 53e846a Thanks @maxwellpeterson! - Fix wrangler preview not propagating the assets binding to preview deployments

  Previously, wrangler preview would upload the asset manifest correctly but the resulting preview deployment had no ASSETS binding (or whatever name was configured under assets.binding). Workers reading from the binding would see undefined and fail at runtime.

  The fix emits the assets binding into the deployment's env map alongside other bindings, mirroring wrangler deploy.

• #13770 beff19c Thanks @petebacondarwin! - Only show accounts available for the current login auth in wrangler whoami and the interactive account picker

  Wrangler now lists the intersection of /accounts and /memberships instead of either endpoint alone, dropping accounts the active OAuth token or API token has no membership in. The accounts field of wrangler whoami --json is filtered the same way. When /memberships is inaccessible to the current auth (e.g. Account API Tokens) Wrangler falls back to /accounts so those tokens continue to work as before.

• #13832 af42fed Thanks @gpanders! - Show containers ssh in wrangler containers --help and in wrangler containers ssh --help

  The containers ssh command was previously hidden, so it did not appear in the list of subcommands shown by wrangler containers --help, and its description was omitted from wrangler containers ssh --help. The command is now listed with its description in both places.

@cloudflare/vite-plugin@1.36.1

Patch Changes

• #13802 a7fd465 Thanks @deodad! - Fix .dev.vars written for vite preview to round-trip values containing quotes

  When the plugin emits dist/<env>/.dev.vars for vite preview, it previously wrote each value as a double-quoted dotenv string with " escaped to \". dotenv (the parser wrangler uses) does not unescape \" inside double-quoted values, so values containing " arrived at the worker with literal backslashes still in them.

  The plugin now quotes strings using the first quote character that does not appear in the value (with the priority order: single → backtick → double), all of which dotenv strips correctly. If a value contains every supported quote character it throws instead of silently corrupting the value.
