# Changelog - April, 2026

## New Features

_No new features this time around. We're busy working on a few major improvements._

## Improvements

Email Config UI/UX

### Language-Based Section Variants

**[Section Variants](https://docs.topol.io/email-editor/guide/conditional-content.html) and [Multilingual Templates](https://docs.topol.io/email-editor/guide/multilingual-templates.html) now work together.** Variants build alternative versions of a section, multilingual templates translate content per language, and the two used to be independent. A variant can now be tied to one or more languages, so each language mutation renders only the sections that belong in it.

Some sections only make sense in certain markets, and forcing a translation elsewhere means more work for the localization team and more clutter for readers. Language-based variants leave those sections out of the languages where they don't belong, without copying the template or hiding content with hand-written Merge Tags. It works the other way too: a market that needs an extra section can get it as a variant scoped to that one language, and the rest of the template stays untouched.

Set `enableSectionVariants` in `TOPOL_OPTIONS`:

```ts
enableSectionVariants: true,
```

With Multilingual Templates also enabled, the editor exposes a built-in `TOPOL_TEMPLATE_LANG` Merge Tag inside the **Variants** condition picker. Pick the languages a variant should appear in. At send time, the variant whose languages match the reader's current language mutation renders.

An existing language Merge Tag in your own system can replace the built-in one:

```ts
languageMergeTag: "MY_CUSTOM_LANG_TAG",
```

For full details, see the [documentation](https://docs.topol.io/email-editor/guide/conditional-content.html#language-based-variants).

Email Config UI/UX

### File Manager Support in the GIF Block

**A [Custom File Manager](https://docs.topol.io/email-editor/guide/custom-filemanager.html) now works from the GIF block too.** Once enabled, the **Custom Source** tab shows **Choose Image** and **Replace** buttons next to the URL input. Either one fires the same `onOpenFileManager` callback the Image block uses, and `TopolPlugin.chooseFile()` writes the returned URL to the GIF block's `src`.

Assets in your own media library could already reach a GIF through the Image block, but the dedicated GIF block was stuck on GIPHY and pasted URLs. That meant two flows for the same kind of file, with authors copy-pasting links for branded or self-hosted GIFs. The GIF block now behaves like the Image block, so either one works.

This is opt-in for backwards compatibility, so existing integrations won't see the file manager buttons in GIF blocks until it's turned on. Alongside the usual `customFileManager` setup, add `enableFileManagerInGif: true` to `TOPOL_OPTIONS`:

```ts
const TOPOL_OPTIONS = {
  customFileManager: true,
  enableFileManagerInGif: true,
  callbacks: {
    onOpenFileManager() {
      // Opens for both Image and GIF blocks.
      // Call TopolPlugin.chooseFile() with the selected URL.
    },
  },
};
```

An `onOpenFileManager` already wired for the Image block needs no changes; the GIF block reuses the same handler. For full details, see the [documentation](https://docs.topol.io/email-editor/guide/custom-filemanager.html#use-custom-file-manager-in-the-gif-block).

Email UI/UX Config

### Merge Tags in Input Fields

**[Merge Tags](https://docs.topol.io/email-editor/guide/merge-tags.html) now insert into form fields, not only text.** Clicking into a supported field opens a picker with all configured tags. Supported fields include button URLs, image alt text and links, video URLs, GIF sources, and social network URLs.

These fields previously accepted plain text only, so using a Merge Tag meant typing the placeholder by hand, which was easy to get wrong. A click into the field now opens a dropdown with every available Merge Tag.

Nothing to configure. As long as `mergeTags` is set in `TOPOL_OPTIONS`, the picker appears automatically.

For full details, see the [documentation](https://docs.topol.io/email-editor/guide/merge-tags.html).

## Bugfixes

-   Email Fixed an issue where Merge Tags lost their formatting when inserted into bold or italic text.
-   Email Fixed an issue where images uploaded through the [Custom File Manager](https://docs.topol.io/email-editor/guide/custom-filemanager.html) into social or carousel items replaced the wrong item.
