Bug Fix Bulletin — v59.0.0

Resolved defects in hotspot copy/paste and background rendering — April 2025

1. Purpose & Scope

This bulletin documents the defect resolutions shipped in Tiled v59.0.0. It serves as the formal record of corrective actions taken, supporting SOC 2 CC7.4 (incident response) requirements for evidence that identified deficiencies were remediated in a timely manner.

2. Defect Resolution Record

Area

Defect Summary

Resolution

Builder 2.0

Hotspot copy/paste reverted link changes

Copying and pasting a hotspot tile that had a click event or link configured was reverting the link to its previous state, discarding any updates made before the copy. The copy/paste operation now correctly preserves all current link and click event configurations on hotspot tiles.

Builder 2.0 — Backgrounds

Background rendering for sub-pages and scroll states (multiple issues)

A series of background rendering defects affecting sub-pages and scroll states have been resolved. Backgrounds were failing to render correctly in specific configurations involving nested scroll states and sub-page transitions. All known background rendering scenarios — including nested scrolls, parallel scroll states, and sub-page backgrounds — have been reviewed and corrected as part of this fix bundle.

3. Background Rendering — Testing Scope

Due to the breadth of the background rendering fix, the following scenarios should receive additional testing coverage in the v59.0.0 QA cycle:

  •   Sub-pages with custom background images or colors — verify backgrounds render correctly in Preview, Viewer, and Share Link.
  •   Scroll states with background overrides — verify backgrounds render at each scroll state transition.
  •   Nested scroll states — verify that inner and outer scroll backgrounds do not bleed or conflict.
  •   1.0 and 2.0 microapps — verify background rendering is consistent across both builder versions.

4. Audit Evidence

For SOC 2 CC4.2 (evaluation of control deficiencies), the following is noted:

  •   The hotspot copy/paste defect caused data integrity loss at the tile configuration level. No customer data or content was lost. The defect affected only in-Builder editing workflow state.
  •   The background rendering defects affected visual output in Preview, Viewer, and Share Link contexts. No personal data or security controls were involved.
  •   Both defects were identified through internal QA processes and resolved within the v59.0.0 release cycle.
