April 2026 Release — Export System Overhaul & Expression Fixes
🚀 April 2026 Release
This release focuses on making the export system more powerful and consistent, while fixing a critical stability issue in the Expression section.
Export System Improvements
Quick View Across All Export Wizards
The eye icon quick view — previously only available in the ChatGPT export — is now available in the Markdown export wizard as well. Preview any library template or uploaded document before deciding to include it.
Save for Export
The ChatGPT Custom GPT workflow now supports "Save for this export" on knowledge files. Make inline edits to any file and save a version specific to the current export — without modifying the original source document.
Template Input Hover Cards
In the Prompt Builder, every template now shows a hover card on its "inputs" badge. At a glance, you can see all required and optional variables before selecting a template. The hover card is role-aware: admins get a link to manage inputs in Settings, while team members see a note that options are managed by the admin.
Admin Template Management
A new Templates tab in Settings gives admins full control over prompt template variables. Edit labels, types, and required status — changes apply project-wide for all team members.
Expression Page Stability
Visual Style Save Fix
Fixed a critical error that prevented saving changes on the Visual Style card. The root cause was missing database columns (platform_voice_rules and situational_tone_guides) that the save function referenced. A database migration added the missing columns, and the save logic was refactored to properly serialize visual and verbal style slots into JSONB.
Release Notes System
This is the first official release note for Brand Kit OS! The release notes system synthesizes granular changelog entries into cohesive, customer-facing narratives. Each release note links back to its associated changelog entries for detailed technical context.

- Standardized section selection across all export wizards with multi-column layout
