# Xponent Communications Control October 2026 (26.3.3) Release Notes

## Overview

This release introduces **RCS Dynamic Calendar Events**, **Landing Page Builder**, and **Backplane Product Discovery–Based Cross-App Navigation** (Waffle Menu) to expand content personalization, authoring, and cross-application navigation capabilities. Continuous Improvement updates include **XCC Template API Pagination** and enhancements to the **Email and** **Email Asset Preview Experience**, helping streamline template management and content validation across devices. The release also includes Bug Fixes to improve the reliability of email preview and review workflows.

- ### RCS Dynamic Calendar Events

RCS Dynamic Calendar Events enable users to create calendar suggestions with start and end times that can vary by recipient, allowing different recipients within a segment to receive events with different schedules. Event times are dynamically supplied by JO or another system during the send workflow. Supported for both card and message suggestions, the feature uses structured variables to distinguish multiple events and maintains the configured suggestions throughout authoring, review, preview, and delivery.
- ### Landing Page Builder

Landing Page Editor and Preview enables users to build static landing pages and preview their responsive behavior across desktop, tablet, and mobile viewports. Custom preview dimensions provide a more accurate representation of how HTML content will render at different screen resolutions, including device-specific content visibility. The editor supports content widths up to 1440 pixels; variables and merge tags are not currently supported.
- ### Backplane Product Discovery–Based Cross-App Navigation (Waffle Menu)

XCC now supports cross-application navigation through the waffle menu, enabling users to easily access other products available to them. The menu automatically displays the appropriate product destinations and provides a faster, more reliable navigation experience across supported applications.

## Continuous Improvements

- ### XCC Template API Pagination

XCC Template APIs make it easier to work with large template libraries by enabling clients to retrieve templates in smaller, manageable sets and quickly narrow results using sorting and filtering. Clients can seamlessly navigate additional results as needed, while existing integrations continue to work without requiring pagination. This capability is available for SMS, MMS, RCS, and landing page templates.
- ### Email and Email Asset Preview Experience

Email and Email Asset previews now use an updated HTML preview. Authors can switch between desktop and mobile views to check how content appears on each device. The preview applies hide-on-desktop and hide-on-mobile settings. It also reflects responsive rules and media queries in the selected viewport. For example, a block set to hide on mobile stays hidden in mobile view. The updated experience helps authors check device-specific layouts and content visibility while editing.

## Bug Fixes

**1466966 / 1381262** - Fixed an issue where the XCC Email Preview and Review experiences could display a blank screen when template rendering failed due to Liquid syntax or composition validation errors. The UI now displays actionable error messages to help users identify and correct template issues during review and approval workflows.
