Major Changes

• #11982 d84e444 Thanks @Princesseuh! - Adds a default exclude and include value to the tsconfig presets. {projectDir}/dist is now excluded by default, and {projectDir}/.astro/types.d.ts and {projectDir}/**/* are included by default.

  Both of these options can be overridden by setting your own values to the corresponding settings in your tsconfig.json file.

• #11987 bf90a53 Thanks @florian-lefebvre! - The locals object can no longer be overridden

  Middleware, API endpoints, and pages can no longer override the locals object in its entirety. You can still append values onto the object, but you can not replace the entire object and delete its existing values.

  If you were previously overwriting like so:

  ctx.locals = {
    one: 1,
    two: 2,
  };

  This can be changed to an assignment on the existing object instead:

  Object.assign(ctx.locals, {
    one: 1,
    two: 2,
  });

Minor Changes

• #11980 a604a0c Thanks @matthewp! - ViewTransitions component renamed to ClientRouter

  The <ViewTransitions /> component has been renamed to <ClientRouter />. There are no other changes than the name. The old name will continue to work in Astro 5.x, but will be removed in 6.0.

  This change was done to clarify the role of the component within Astro's View Transitions support. Astro supports View Transitions APIs in a few different ways, and renaming the component makes it more clear that the features you get from the ClientRouter component are slightly different from what you get using the native CSS-based MPA router.

  We still intend to maintain the ClientRouter as before, and it's still important for use-cases that the native support doesn't cover, such as persisting state between pages.

Patch Changes

• #11987 bf90a53 Thanks @florian-lefebvre! - render() signature now takes renderOptions as 2nd argument

  The signature for app.render() has changed, and the second argument is now an options object called renderOptions with more options for customizing rendering.

  The renderOptions are:

  • addCookieHeader: Determines whether Astro will set the Set-Cookie header, otherwise the adapter is expected to do so itself.
  • clientAddress: The client IP address used to set Astro.clientAddress.
  • locals: An object of locals that's set to Astro.locals.
  • routeData: An object specifying the route to use.

• #11991 d7a396c Thanks @matthewp! - Update error link to on-demand rendering guide
