# Changelog - September, 2026

## New Features

_No new features this month. This release focuses on improvements and bug fixes, with more in the works._

## Improvements

Email Blocks Config

### Custom Order for Default Premade Block Groups

**Topol's default [premade block](https://docs.topol.io/email-editor/guide/premade-blocks.html) groups can now sit anywhere among your own groups.** Inside the `premadeBlocks.blocks` array, a preset marker such as `{ preset: "footer" }` is replaced by Topol's default group of that type, in the same position. The four presets are `header`, `content`, `ecommerce`, and `footer`, and the sidebar shows the groups in the same order as the array.

Custom groups used to always come first, followed by Header, Content, E-commerce, and Footer in a fixed order, so a group of dynamic products could never sit next to E-commerce. The `override` flag still decides what happens to the default groups you don't list: with `override: false` they are added at the end, and with `override: true` they are left out.

```ts
premadeBlocks: {
  override: false,
  blocks: [
    { preset: "header" },
    { preset: "content" },
    { name: "Dynamic products", blocks: [/* ... */] },
    { preset: "ecommerce" },
    { preset: "footer" },
  ],
},
```

Each preset can appear only once. A repeated or unknown preset is rejected, and the editor shows an error message. For full details, see the [documentation](https://docs.topol.io/email-editor/guide/premade-blocks.html#placing-the-default-groups).

Email Config Storage

### Option to Disable the Image Editor

**Setting `imageEditor: false` now turns off the built-in [Image Editor](https://docs.topol.io/email-editor/guide/image-editor.html).** The **Edit** and **Create new image** buttons disappear from the image settings, and **Create new image** disappears from the built-in File Manager.

When an image is saved in the Image Editor, the editor uploads it itself, either to Topol storage or, with [Self-hosted Storage](https://docs.topol.io/email-editor/guide/self-hosted-storage.html), to your `IMAGE_UPLOAD` endpoint. Turning the Image Editor off keeps every image in your own storage. The option was already accepted in the configuration, but until now it did nothing.

```ts
imageEditor: false,
```

The option defaults to `true`. For full details, see the [documentation](https://docs.topol.io/email-editor/guide/image-editor.html#disable-the-image-editor).

## Bugfixes

-   Email Landing Page Closing or removing one panel, block, or field no longer turns off features elsewhere in the editor, such as comment highlighting, panel resizing, and image fields.
-   Email Landing Page The [Tiptap](https://docs.topol.io/email-editor/guide/text-editor-configuration.html#tiptap-editor-configuration) formatting toolbar is now loaded only for the text block being edited, not for every text block on the canvas.
-   Email Landing Page Failed image uploads now show an error message, including uploads to a [self-hosted](https://docs.topol.io/email-editor/guide/self-hosted-storage.html) `IMAGE_UPLOAD` endpoint, and the file size limit message shows real text instead of a raw translation key.
-   Email Landing Page Fixed the **Move to folder** and **Save block** folder pickers in [saved blocks](https://docs.topol.io/email-editor/guide/saved-blocks.html) not showing all folders.
-   Email Landing Page A single corrupted saved block no longer stops the whole saved blocks library from loading.
-   Email Landing Page The saved blocks panel now scrolls back to the top when you open a folder, search, or change the type or sort order.
-   Email Landing Page Number inputs in the settings panels stay in place when the reset (×) button appears.
-   Email Landing Page Icons in the image editor's Elements panel now display correctly instead of as broken images, and insert reliably when clicked.
-   Email Emails keep their mobile column stacking in Gmail even when the template contains a broken color value, such as `##9E896F`.
-   Email Fixed [merge tags](https://docs.topol.io/email-editor/guide/merge-tags.html) used as color values, such as `#`, being replaced with the default color. Templates saved between September 2 and September 9 may need those colors set again.
-   Email [Custom block](https://docs.topol.io/email-editor/guide/custom-block.html) attributes set as `{ value, disabled }` keep their values instead of falling back to the block defaults.
-   Email A column divider can no longer be dragged past the point where the column becomes narrower than its content.
-   Email Fixed HTML generation through the API, and save and preview, failing for templates in the older MJML 3 format.
-   Email Fixed TinyMCE text editing breaking when a color, column width, or section order changed while TinyMCE was still loading, and button blocks reloading TinyMCE on every color change.
-   Email [Loop Blocks](https://docs.topol.io/email-editor/guide/loop-blocks.html) render correctly in Preview with Merge Tags, test emails, and exported HTML, and invalid loop data no longer breaks the whole preview.
-   Email The element defaults in [default template settings](https://docs.topol.io/email-editor/guide/default-settings.html) now show the real default values instead of 0, for example the button's corner radius.
-   Landing Page Fixed the fullscreen button not working when the Landing Page Editor is embedded with the loader script.
