Highlights from the newest Microsoft Dynamics 365 Business Central 2025 Release Wave 1 Update
Microsoft has officially rolled out Update 26.2 for Dynamics 365 Business Central, part of the 2025 Release Wave 1. This is a minor update following the major platform and application improvements introduced in April with Version 26.0. Update 26.2 is available as of June 2025 and includes key platform stability, performance, and compliance enhancements to keep environments secure and current.
At TheTestMart, we’re closely tracking each update cycle to help teams validate, test, and deploy changes with confidence. Here’s what you need to know about this latest release.
Update 26.2: What’s Included
According to Microsoft’s official release notes, this update contains:
- Application Build: 26.2.34832
- Platform Build: 26.0.34736
While no major new features were introduced, this release continues Microsoft’s emphasis on incremental improvement. You’ll find updates focused on:
- Minor bug fixes across finance, warehouse, and configuration
- Localization improvements for regulatory compliance
- Performance optimizations in batch processing and page loading
These refinements are essential for maintaining reliability between major update waves.
Understanding the Business Central Release Cadence
Microsoft delivers two major Business Central updates per year, typically in April and October. These major updates introduce new features, architecture improvements, and usability upgrades. Each major update is followed by monthly minor updates like 26.1 and 26.2, which deliver bug fixes and optimizations without introducing breaking changes.

Why These “Minor” Updates Still Deserve Testing Attention
Even when no new features are introduced, minor updates can still affect core business processes. That’s why TheTestMart recommends validating every release—especially in areas like:
- Workflows across finance, supply chain, or sales
- Role-based permissions and user training
While preview environments are only provided for major updates, organizations can still use sandbox environments to test the impact of monthly updates like 26.2. This is especially important for customers with custom extensions or integrations.
You can manage your update timing and configuration settings in the Business Central Admin Center, where Microsoft provides controls for update deferral, scheduling, and environment setup.
