February 2026: TI4_map_generator_bot delivered a critical reliability improvement for image exports. The fix ensures correct handling of alpha channels when saving images to formats that do not support transparency (JPG/WebP) by redrawing onto a non-transparent canvas prior to encoding. This prevents encoding errors and yields consistent outputs across formats. The change is encapsulated in commit d8a0868763aef9ba72f69d125c423c3fa1d77157 (#4376).
