What's New in MelonWallet
1.1
September 4, 2026
What's New in Version 1.1 [CRITICAL HOTFIX] Recommended for all users to update immediately. • Critical Crash Fix on Large Documents: Resolved a high-priority memory leak issue where importing multi-signature PDF documents (over 64 pages) could cause sudden application termination on iOS 26 devices. • Export Fidelity & Duplex Alignment Fix: Fixed a critical bug in the 2-up signature imposition engine where certain back-page rotation profiles could invert duplex orientation during vector export. • Sandboxed File Integrity: Addressed a severe local cache synchronization glitch that could lead to project package (.melonpkg) loading failures after cold launches. • Calibration Stability: Enhanced core graphic memory allocation during manual printer calibration to prevent rendering freeze. We strongly recommend all users upgrade to Version 1.1 to ensure project stability and prevent unexpected data loss during print preparation.
