We’re excited to announce that SB/XA 6.6.5 is available as of June 8, 2026. This release represents a major step forward, delivering meaningful improvements in modernization, security, and performance you can rely on.
Modernization & Architecture Enhancements
Native ARM64 Support for the Rich Client
The SB/XA Rich Client now includes native ARM64 support for modern Windows devices running ARM processors, such as Windows 11 systems with Snapdragon CPUs.
What this means for you:
- Improved performance and efficiency on ARM-based hardware
- Native execution on Windows 11 ARM64 environments
- Automatic fallback to x86 emulation on Windows 10 ARM64 systems
As part of this enhancement, the Rich Client now runs on .NET Framework 4.8.1 bringing modernized project files that make it easier than ever for customers to build and customize Rich Clients aligned with the new architecture.
Security Improvements
Security enhancements in this release address both cryptographic standards and client-side vulnerabilities.
OpenSSL Upgrade to Version 3.5
The OpenSSL library has been upgraded to version 3.5 for SSL/TLS Telnet and SFTP components.
Benefits:
- Addresses known vulnerabilities in older OpenSSL versions
- Aligns with current industry security standards
- Ensures continued support as older OpenSSL versions reach end-of-life
Protection Against DLL Hijacking
A phantom DLL hijacking vulnerability in SBClient has been addressed, strengthening protection against unauthorized code execution on Windows systems.
Improved SSH Session Security
Several SSH-related improvements enhance both security and usability:
- SSH keyboard timeout handling fixed
Session timeouts are no longer reset when a user unlocks the screen after a keyboard inactivity timeout, preventing unintended session extension. - Option to hide usernames during SSH login
Administrators can now configure SBClient to suppress username echoing during SSH authentication, reducing the exposure of sensitive login details.
Performance & Stability Enhancements
This release delivers noticeable performance and stability improvements to help you work faster and more efficiently every day:
- Quicker, more reliable sign‑on, reducing the risk of timeouts during authentication
- Improved Rich Client stability when switching accounts in UniData environments
- Consistent window positioning when reconnecting SBClient sessions for a smoother workflow
- Enhanced scrolling performance in the SE editor, even when working with long lines in third‑party terminal emulators
Together, these enhancements provide a smoother, more responsive, and more reliable experience helping you stay productive throughout daily operations.
User Interface & Usability Fixes
Several UI and interaction issues have been addressed to improve consistency and predictability:
- Output screen options now correctly remove OK, Previous, and Next buttons when configured
- Grid footer fields in the XUI client now reset correctly after screen acceptance
- Updating passwords is now easier and more reliable, with improved Rich Client workflows that fully support password rollover scenarios.
