Key features include critical security enhancements, streamlined deployment and support for cross-platform client access for ODBC, JDBC and ADO.NET environments, while promoting a "code once, connect everywhere" model. 2025-07-30T14:54:39Z 2026-04-09T16:59:04Z Todd Wright We’re excited to announce the release of OpenAccess SDK 9.0, a major milestone in our journey to deliver secure, high-performance, and standards-compliant data connectivity. This release is packed with critical security enhancements, streamlined deployment features, and continued support for cross-platform client access—all designed to empower developers and enterprises alike.

Security-First: Built for Today’s Compliance Needs

Security was the cornerstone of this release. With OpenAccess SDK 9.0, we’ve made significant strides to make your data access layer more robust and compliant:

  • Upgraded OpenSSL to 3.0.16, aligning with modern encryption standards.
  • Deprecated TLS v1.0 and v1.1, eliminating outdated protocols to reduce vulnerability exposure.
  • Removed legacy dependencies like msvcr100.dll and LDAP support, simplifying the runtime environment and reducing attack surfaces.
  • Bundled ICU 74.1 as a single library file, streamlining deployment and minimizing potential integration issues.

These changes reflect our commitment to delivering a secure foundation for your data connectivity infrastructure.

Upgrade Made Easy

We know that upgrading SDKs can be daunting. That’s why OpenAccess SDK 9.0 is designed for ease of transition:

  • Backward Compatible—OpenAccess 8.1 clients can connect to the OpenAccess 9.0 server
  • Forward Compatible—OpenAccess 9.0 clients can connect to the OpenAccess 8.1 server
  • No backend changes required—your existing data source remains untouched.
  • Unified deployment—leveraging the new build environment (Visual Studio 2022 for Windows, GCC 8.5 for Linux) brings compatibility across modern platforms.
  • Simplified prerequisites—with clear guidance on Microsoft Visual C++ Redistributable, setup is straightforward and predictable.

Whether you're upgrading from 8.1 or integrating for the first time, OpenAccess SDK 9.0 makes the process smooth and reliable.

Code Once, Connect Everywhere

One of the most powerful aspects of OpenAccess SDK is its multi-client support. With a single server implementation, you instantly unlock access for:

  • ODBC – for cross-platform compatibility
  • JDBC – for Java-based applications
  • ADO.NET – for .NET environments
