Changelog

v1.1.0 — February 2026

New Features

Split Mode Editor

Added a third editing mode alongside WYSIWYG and Code: Split Mode shows the code editor on the left and a live visual preview on the right, updating in real time as you type.

Previously, switching between code and preview required toggling modes. Split Mode eliminates this context switch for developers building layouts — you can see the result of every HTML and CSS change immediately without leaving the editor.

When to use: Complex layouts, CSS fine-tuning, or learning which markup produces which visual result. Note that Split Mode is more CPU-intensive on low-powered devices — for very long blocks (500+ lines), Code Mode alone is more responsive.

Twig Variables in Block Content

Blocks now support Twig template variables for dynamic, personalised content. Available variables include the logged-in customer's first name, language code, currency, cart total, and more.

Example — personalised greeting:

{if $customer.is_logged_in}
<p>Welcome back, {$customer.firstname}!</p>
{/if}

Variables are evaluated server-side — the rendered output sent to the browser contains the resolved values, not the Twig syntax. See the Configuration Guide for the full variable reference.

Per-Block Cache Clear

Added a "Clear Cache" action button on each block row in the block list. Previously, clearing the cache purged all blocks simultaneously.

Per-block cache clearing is useful when you want to push a change to one block immediately without affecting the cached versions of other blocks on the same page. Particularly useful for high-traffic stores where a full cache purge causes a brief period of uncached (slower) page renders for all visitors.

Block Export and Import

Added Export and Import buttons to the block list toolbar. Blocks can be exported as a JSON file containing the block's content, hook, conditions, schedule, and A/B test settings (but not test result data). Import creates a new block from a JSON file.

Use cases:

  • Backup before making significant changes
  • Copy blocks between PrestaShop shops or between the staging and production environments
  • Share block templates with other store owners

Improvements

  • Responsive visibility controls redesigned with clearer labels. The three device toggles (Desktop, Tablet, Mobile) now show the screen width breakpoints directly in the toggle label, eliminating ambiguity about which breakpoints are used.

  • Visual hook selector updated with new hooks for PrestaShop 9.x compatibility. The following hooks are newly supported: displayAfterProductAdditionalInfo, displayProductExtraContent, displayCheckoutSummaryTop.

  • Block list performance improved for stores with 50+ blocks. The list now uses virtual scrolling and deferred rendering, reducing initial load time from 2–4 seconds to under 500ms for large block catalogues.

  • A/B test results panel now shows a confidence progress bar that updates in real time (polling every 60 seconds) when the results panel is open. Previously required a page refresh to see updated data.

Bug Fixes

  • Fixed: Blocks assigned to displayProductTab and displayProductTabContent did not render correctly on PrestaShop 9.x due to a tab markup structure change in the default theme.
  • Fixed: Date range conditions evaluated using the server's system timezone rather than the store's configured timezone (International → Localization). Schedules set to Polish time now activate and deactivate at the correct Polish time.
  • Fixed: The "Duplicate" action created blocks with all conditions removed. Duplicated blocks now copy conditions, schedule, and responsive visibility settings exactly.
  • Fixed: On PrestaShop multistore, blocks created in "All Shops" context appeared in the block list of specific shop contexts as editable. These blocks are now shown as read-only in specific shop contexts, with a note to switch to "All Shops" to edit them.
  • Fixed: The block name field did not accept special characters (umlauts, Polish diacritics, accented characters). Corrected by using UTF-8 encoding throughout the name save and retrieve flow.
