What's New in Borderline
2.4
October 20, 2026
Our biggest accuracy release yet. NEW: A redesigned Residency screen. See where you are in your qualifying period and every rule next to its limit. Tap a rule to see the exact trips that count toward it. NEW: Japan pathways. Track Permanent Residence and Naturalization — with Japan's guideline-based day limits clearly marked as guidance, not statutory rules. NEW: Cited sources everywhere. Tap any threshold to open the official rule behind it — gov.uk, USCIS, canada.ca, Japan ISA. Verify every number yourself. IMPROVED: Clearer informational framing throughout. Borderline shows your logged days beside the cited official rule and leaves the judgment to you and your adviser. FIXED: Canada citizenship no longer auto-credits days before your PR date. The IRCC pre-PR half-day credit requires temporary resident status, which travel history alone can't confirm — check IRCC's official calculator if it applies to you. FIXED: A deep correctness audit across the whole app — leap-year rolling windows, one timezone convention across every tab, phantom border crossings filtered out, exports that re-import losslessly, and more reliable subscription restore. IMPROVED: Fully localized in Traditional Chinese (繁體中文) and Simplified Chinese (简体中文), including every new feature.
