Just one day after 1.3.0, Uni-Verein 1.3.1 follows with a clear focus: noticeably better frontend performance and an important security fix.

Improvements​

• 🚀 Lazy loading of frontend routes: Page components (Mail, Members, SEPA, Contributions, user/link/contribution-plan/email/creditor/general/member-category configuration, Audit, Backup) are now loaded on demand instead of being bundled into the initial payload, the main bundle shrinks from about 1.4 MB to about 577 kB
• 🖼️ The icon picker ("Select icon") now caps the number of rendered icon tiles at 250 and prompts for a more specific search beyond that, instead of mounting all ~8,600 icons at once, this previously froze the UI for over a second every time the dialog was reopened
• ⏳ The icon picker now waits for icons to be fully loaded/cached before revealing the grid, showing a loading spinner in the meantime instead of an empty or partially populated dialog
• 🧹 IconPickerDialog.tsx no longer redundantly dynamically imports muiIcons for loadIconNames when it's already imported statically elsewhere, resolving a Vite build warning and allowing the module to be chunked correctly
• ⚙️ The enforce-source-branch CI job from 1.3.0 now also runs for pull requests targeting development, so merging main back into development isn't blocked by a status check that previously only evaluated PRs targeting main

Bug Fixes​

• 🐛 Vite's chunk-size warning for the @mui/icons-material barrel (loaded on demand by the icon picker) is now suppressed via chunkSizeWarningLimit, since that chunk is expected to be large and is never part of the initial page load

Security​

• 🔐 Bumped the brace-expansion npm override to ^5.0.8 to close a high-severity ReDoS advisory (exponential-time expansion of consecutive non-expanding {} groups); the previous override version had drifted out of sync with the lockfile and a duplicate vulnerable copy remained nested under filelist

Why These Updates Matter​

The icon picker in particular had felt noticeably sluggish, thanks to lazy loading and capping the number of rendered icons, the UI now responds much more smoothly. The smaller main bundle also means Uni-Verein loads faster, especially on mobile connections. The ReDoS fix additionally closes a high-severity vulnerability in a transitive dependency.
