---

Nutrient Web SDK 1.24 is a maintenance release. It narrows `isEditableComment` to the comments that already exist, so marking comments read-only no longer removes the reply editor. Document operations now save pending changes before they run, which keeps unsaved annotations when `autoSaveMode` is `DISABLED`. The note editor and the note and comment indicators get accessible names for screen readers. It also fixes custom fonts with multiword names, several text annotation editing issues, and undo and preset regressions. It fixes worker startup under a Trusted Types Content Security Policy as well. See the [changelog](https://www.nutrient.io/guides/web/changelog.md#1.24.0) for full details.

### isEditableComment no longer governs replies

`isEditableComment` used to receive a temporary draft comment for every thread, and returning `false` for that draft removed the reply editor. The callback’s contract covers existing comments only, so drafts now skip it. A callback that returns `false` marks saved comments read-only, and the user can still reply:

```js

NutrientViewer.load({
  // Before 1.24, this also removed the reply editor from every thread.
  // It now only prevents editing and deleting existing comments.
  isEditableComment: () => false,
});

```

**If you relied on the draft to block replies**, that check no longer runs. A draft used to arrive with `pageIndex` set to `null`, so a callback that returned `comment.pageIndex!== null` stopped replies in every thread. In server-backed mode, collaboration permissions now govern reply rights through the `reply` action on the `comments` content type. In standalone mode, replace the editor area with the `ui.commentThread.editor` slot. The slot applies to every thread, so it also removes the editor for the first comment of a new thread. `instance.setIsEditableComment()` follows the same contract. For more information, refer to the [comments](https://www.nutrient.io/guides/web/annotations/comments-and-replies/comments.md) and [collaboration permissions](https://www.nutrient.io/guides/web/collaboration-permissions/defining-permissions.md) guides.

### Document operations save unsaved changes first

With `autoSaveMode` set to `DISABLED`, `instance.applyOperations()` deleted every unsaved annotation in the document, on every page, and `hasUnsavedChanges()` then reported `false`. The Document Editor uses the same path, so rotating, moving, duplicating, or removing a page in its UI and clicking Save lost the same annotations. The viewer now saves pending changes before it applies the operations, as printing already does. The operations then act on a document that contains them, so an annotation on a rotated or moved page moves with its page:

```js

await instance.applyOperations([
  { type: "rotatePages", pageIndexes: [1], rotateBy: 90 },
]);

instance.hasUnsavedChanges(); // false: the pending changes were saved first.

```

If the save fails, the returned promise rejects with a `SaveError` and the document isn’t changed. In server-backed mode, the save sends the pending changes to Document Engine before the page operation. The page operation itself already went to Document Engine at once in every mode. One case changes for code that relied on the old behavior. In server-backed mode, deleting annotations and then reimporting them with the same IDs through the `applyInstantJson` operation used to bring them back. This worked because the old behavior dropped the pending deletes. The deletes are now saved first, and Document Engine doesn’t recreate a deleted record ID, so a reimport needs new IDs. For more information, refer to the [autosave](https://www.nutrient.io/guides/web/features/saving.md) guide.

### Screen reader support for notes and comments

The note editor and the note and comment indicators have accessible names. Screen readers announce a selected note with its content and name its Close button. For more information, refer to the [accessibility](https://www.nutrient.io/guides/web/viewer/accessibility.md) guide.

### Trusted Types Content Security Policy

Workers now start under a Trusted Types Content Security Policy that allowlists the documented policies. The failure broke text selection highlights in PDFs and prevented Office documents from opening. The SDK now creates its Trusted Types policy once per bundle, so `'allow-duplicates'` isn’t needed. For more information, refer to the [Content Security Policy](https://www.nutrient.io/guides/web/troubleshooting/content-security-policy.md) guide.

Document Engine 1.5.6 or later can run this release. In server-backed mode, using `SearchType.WORD_BASED`, removing password protection during PDF export, and removing annotation notes after an XFDF roundtrip require Document Engine 1.16.0 or later. Document-defined annotation tab order, `Annotation.createdBy`, `overprintPreview`, and `blackRendering` require Document Engine 1.18.0 or later. Compound measurements are standalone mode only and are ignored by Document Engine. See the [Web SDK and Document Engine compatibility requirements](https://www.nutrient.io/guides/document-engine/viewer/client-integration/web.md#version-compatibility).
