We are thrilled to announce the official release of XLS Padlock 2025.1. This update is focused on delivering a faster and more stable experience for both developers and end-users.
Key highlights of the 2025.1 version include:
- Faster Performance: Using the Zstandard compression algorithm results in quicker compilation and application startup times.
- Expanded Language Support: We’ve added localization for Simplified and Traditional Chinese for compiled workbook apps. We may also add Chinese translation for XLS Padlock GUI itself in the future.
- Enhanced Stability: We updated the core spreadsheet engine and optimized multithreading loops.
- Improved Compilation: The build process is now smarter and was internally optimized.
➡️ This version also addresses several user-reported bugs to improve overall reliability. For a detailed list of all changes, please see our dedicated blog post.
