v2026.4.0

What's Changed

Features

• Brand-new design matching stash.hexul.com — dark/light adaptive theme, colored type badges, bottom toolbar
• Theme picker in Settings (Auto / Light / Dark)
• Hover-revealed action buttons (Preview for images/files, Open for URLs)
• Visible pin indicator for pinned entries
• Image thumbnails at trailing edge of image rows
• Custom thin scrollbar that fades in during scroll
• Source attribution: CleanShot, Shottr correctly identified instead of the visible window

Performance

• Smooth scrolling — entries cached in @State, no per-frame database refetch
• Fast image rendering via lazy thumbnails (CGImageSourceCreateThumbnailAtIndex)
• Faster encryption — keychain key cached

Fixes

• Image clipboard reliability — four-tier extraction handles screenshot tools that ship promise-only image data
• Empty-entry filtering at the monitor (Arc tab-switch noise)
• Confirmation dialogs no longer wedge the popover

Other

• Deployment target bumped to macOS 15
• Debug builds signed with Developer ID for stable keychain ACL across rebuilds
