Changelog - March, 2025

New Features

Email Performance

Lambda Region

The Lambda Region setting picks the AWS region where the Plugin's serverless functions run. The choice is between Frankfurt (eu-central-1) and Northern Virginia (us-east-1), and it determines where the backend logic executes.

The nearest region means fewer network round-trips, so templates render faster and API calls complete with lower latency. A European data center also simplifies GDPR and other data-residency compliance, while the U.S. region suits North American workloads.

Add or update the lambdaRegion key in TOPOL_OPTIONS. Left unset, it defaults to eu-central-1:

  lambdaRegion: "eu-central-1", // "eu-central-1" for Frankfurt
                                // "us-east-1" for N. Virginia

For full configuration details, see the documentation.

Email UX/UI

Hover Preview for Saved Blocks

Hovering over a saved block's thumbnail in the Premade Blocks panel now shows an instant preview. A lightweight pop-up renders the block in full, content and layout included, with no need to drag it onto the canvas first.

Inspecting a block's real appearance before insertion removes the guesswork. Designers can scan dozens of saved components and spot the right header, footer, or call-to-action without cluttering the editor.

Improvements

Email Config

New Configuration Option for Merge Tags

Calling window.TopolPlugin.setMergeTags(yourMergeTagsArray) now swaps the default merge-tag sets at runtime, loading different tag groups without rebuilding the plugin. For full details, see the documentation.

Email UX/UI

Replaced Missing Images in Premade Templates

Several premade templates showed broken or missing images. As a temporary measure, a universal placeholder now fills in for every missing asset. A full review of the Premade Templates is underway for a permanent fix.

Email Blocks UX/UI

Improved Border-radius Settings

A Content Block's border-radius can now take a single value applied to all four corners, or a separate value per corner (top-left, top-right, bottom-right, bottom-left) for custom shapes.

Email Blocks UX/UI

Inner vs. Outer Column Offsets

A column's offset can now apply inside its own padding (inner offset) or outside its container (outer offset), giving precise control over how columns shift relative to their content and neighboring blocks.

Bugfixes

• Email Fixed an issue where removing the link from a Video block left an empty, zero-dimension placeholder in the template.
• Email Resolved a bug where deleting the text label of a Button block collapsed it to zero dimensions while it remained in the template.
• Email Resolved an issue where HTML conditional comments inside an HTML Block were incorrectly flagged as invalid code.
