+### Deprecated: exposed `astro:transitions` internals
+
+<SourcePR number="14989" title="feat!: deprecate transitions exports" />
+
+In Astro 5.x, some internals were exported from `astro:transitions` and `astro:transitions/client` that were not meant to be exposed for public use.
+
+Astro 6.0 removes the following functions and types as exports from the `astro:transitions` and `astro:transitions/client` virtual modules. These can no longer be imported in your project files:
+
+- `createAnimationScope()`
+- `isTransitionBeforePreparationEvent()`
+- `isTransitionBeforeSwapEvent()`
+- `TRANSITION_BEFORE_PREPARATION`
+- `TRANSITION_AFTER_PREPARATION`
+- `TRANSITION_BEFORE_SWAP`
+- `TRANSITION_AFTER_SWAP`
+- `TRANSITION_PAGE_LOAD`
+
+#### What should I do?
+
+Remove any occurrences of `createAnimationScope()`:
+
+```ts del={1}
+import { createAnimationScope } from 'astro:transitions';
+```
+
+Update any occurrences of the other deprecated exports:
+
+```ts del={1-4,6,9} ins={7,10}
+import {
+  isTransitionBeforePreparationEvent,
+  TRANSITION_AFTER_SWAP,
+} from 'astro:transitions/client';
+
+console.log(isTransitionBeforePreparationEvent(event));
+console.log(event.type === 'astro:before-preparation');
+
+console.log(TRANSITION_AFTER_SWAP);
+console.log('astro:after-swap');
+```

 ## Removed
 
 The following features have now been entirely removed from the code base and can no longer be used. Some of these features may have continued to work in your project even after deprecation. Others may have silently had no effect.
