What's New in LockZero Premium
1.0.6
May 18, 2026
- LISTS WITH ITEMS OF ANY LENGTH Long items now wrap to multiple lines. The edit field accepts multiline too, and the list scrolls to top automatically. Large lists (30+ items) now scroll all the way to the end. - SMARTER SHARED-LIST IMPORT When receiving a list, the app asks which group to import into. If a note with the same title exists, you choose: replace, merge items, or cancel. - BUG FIXES Fixed crash when receiving a `.lockzero` file from another LockZero install. Shared lists no longer prompt for a wrong export passphrase on import. Improved performance on large lists.
