BeamNG Mod Manager 🧡 v0.6.3: Foundation Hardening: Security fixes & Safer Deletes

Released July 1, 2026

Hey everyone! 👋 This one was all about making BMM sturdier under the hood. It’s a “sleep-better-at-night” release — a big pass of security tightening, plus a bunch of fixes that make the app more careful with your files and more honest about what it’s doing. Here’s the rundown: 

🔒 Security, top to bottom 

We did a full hardening sweep across the whole app: thumbnails are now served through a much stricter path check, the app window runs fully sandboxed, unexpected pop-ups and navigation are blocked, BMM will only ever open folders it actually manages, and the shipped app runs under a tighter content-security policy. You won’t see any of this day to day — that’s the point. It just quietly closes doors. 

🛟 Safer, smarter deletes 

• Locked files no longer get lost — if you try to delete a mod whose .zip is open in another program, BMM now tells you the file is in use and keeps the mod safely in your library — custom thumbnail and all — instead of quietly losing track of it.

• Your last copy is protected — "Import From Game/BeamMP" will never remove a copy of a mod whose Mod Storage original has gone missing. If it’s the only copy you have left, we leave it exactly where it is.

• Bulk deletes report the truth — deleting several mods at once now tells you exactly how many were removed — and flags any file that couldn’t be.

📊 Honest counters 

• Space Saved stays honest in more corners — a cross-drive combine that has to write a copy back no longer counts as a saving, and neither does a delete that didn’t actually happen. 

• Conflicts & Duplicates counts always match the page — even while a search or author filter is active, the number in the sidebar equals what you actually see. 

✨ Little things 

Small polish — the “also delete file” checkbox resets when you switch mods, and the Wall of Supporters now handles two patrons who share a display name.

Thanks as always for keeping BMM going — this kind of foundation work is exactly what your support allows me to do.

Cheers!
