+Adds a new variant `sync` for the `astro:config:setup` hook's `command` property. This value is set when calling the command `astro sync`.
+
+If your integration previously relied on knowing how many variants existed for the `command` property, you must update your logic to account for this new option.

+Fixes a bug in the logic of `Astro.rewrite()` which led to the value for `base`, if configured, being automatically prepended to the rewrite URL passed. This was unintended behavior and has been corrected, and Astro now processes the URLs exactly as passed.
+
+If you use the `rewrite()` function on a project that has `base` configured, you must now prepend the base to your existing rewrite URL:
+
+```js
+// astro.config.mjs
+export default defineConfig({
+  base: '/blog'
+})
+```
+
+```diff
+// src/middleware.js
+export function onRequest(ctx, next) {
+-  return ctx.rewrite("/about")
++  return ctx.rewrite("/blog/about")
+}
+```

+Adds a new, optional property `timeout` for the `client:idle` directive. 
+
+This value allows you to specify a maximum time to wait, in milliseconds, before hydrating a UI framework component, even if the page is not yet done with its initial load. This means you can delay hydration for lower-priority UI elements with more control to ensure your element is interactive within a specified time frame.
+
+```astro
+<ShowHideButton client:idle={{timeout: 500}} />

+Adds support for connecting Astro DB to any remote LibSQL server. This allows Astro DB to be used with self-hosting and air-gapped deployments.
+
+To connect Astro DB to a remote LibSQL server instead of Studio, set the following environment variables:
+
+- `ASTRO_DB_REMOTE_URL`: the connection URL to your LibSQL server
+- `ASTRO_DB_APP_TOKEN`: the auth token to your LibSQL server
+
+Details of the LibSQL connection can be configured using the connection URL. For example, `memory:?syncUrl=libsql%3A%2F%2Fdb-server.example.com` would create an in-memory embedded replica for the LibSQL DB on `libsql://db-server.example.com`.
+
+For more details, please visit [the Astro DB documentation](https://docs.astro.build/en/guides/astro-db/#libsql)

+
+Adds a new option `fallbackType` to `i18n.routing` configuration that allows you to control how fallback pages are handled.
+
+When `i18n.fallback` is configured, this new routing option controls whether to [redirect](https://docs.astro.build/en/guides/routing/#redirects) to the fallback page, or to [rewrite](https://docs.astro.build/en/guides/routing/#rewrites) the fallback page's content in place.
+
+The `"redirect"` option is the default value and matches the current behavior of the existing fallback system.
+
+The option `"rewrite"` uses the new [rewriting system](https://docs.astro.build/en/guides/routing/#rewrites) to create fallback pages that render content on the original, requested URL without a browser refresh.
+
+For example, the following configuration will generate a page `/fr/index.html` that will contain the same HTML rendered by the page `/en/index.html` when `src/pages/fr/index.astro` does not exist.
+
+```js
+// astro.config.mjs
+export default defineConfig({
+  i18n: {
+    locals: ["en", "fr"],
+    defaultLocale: "en",
+    routing: {
+      prefixDefaultLocale: true,
+      fallbackType: "rewrite"
+    },
+    fallback: {
+      fr: "en"
+    },
+  }
+})
+```

+
+Adds a new object `swapFunctions` to expose the necessary utility functions on `astro:transitions/client` that allow you to build custom swap functions to be used with view transitions. 
+
+The example below uses these functions to replace Astro's built-in default `swap` function with one that only swaps the `<main>` part of the page:
+
+```astro
+<script>
+import { swapFunctions } from 'astro:transitions/client';
+
+document.addEventListener('astro:before-swap', (e) => { e.swap = () => swapMainOnly(e.newDocument) });
+
+function swapMainOnly(doc: Document) {
+  swapFunctions.deselectScripts(doc);
+  swapFunctions.swapRootAttributes(doc);
+  swapFunctions.swapHeadElements(doc);
+  const restoreFocusFunction = swapFunctions.saveFocus();
+  const newMain = doc.querySelector('main');
+  const oldMain = document.querySelector('main');
+  if (newMain && oldMain) {
+    swapFunctions.swapBodyElement(newMain, oldMain);
+  } else {
+    swapFunctions.swapBodyElement(doc.body, document.body);
+  }
+  restoreFocusFunction();
+};
+<script>
+```
+
+See the [view transitions guide](https://docs.astro.build/en/guides/view-transitions/#astrobefore-swap) for more information about hooking into the `astro:before-swap` lifecycle event and adding a custom swap implementation.
