Release Notes - January

January, 2026 – Laying the Foundation for Faster Growth
In January, we focused on tuning the core Seamless engine for speed, stability and long‑term scalability. Behind the scenes, we upgraded key platform services, refreshed our technology stack and expanded automated testing. For you, this means a faster, more reliable foundation that’s ready to support new products, higher volumes and continued growth throughout 2026.

Enhanced Payment Flexibility & Claims Data Consistency

1. More efficient back‑office APIs for large JSON payloads

• Component: BOP (Back‑Office Portal)

To improve performance and scalability for all tenants, we’ve optimized how the back‑office portal talks to our core APIs. For API resources that can return a lot of data (for example, policies or complex reference objects), BOP now explicitly requests only the fields it needs. This “sparse fieldset” approach:

• Reduces payload sizes and network latency,
• Lowers the risk of timeouts on heavy back‑office screens, and
• Provides a more predictable performance baseline as we add new attributes over time.

The change is fully backwards compatible and applies automatically to all Seamless tenants.

2. Platform upgrade: .NET services moved to .NET 10

• Component:
  • Agency Configuration
  • Compliance
  • Documents
  • Finance
  • Migration
  • Motor Registry
  • Pricing
  • Reinsurance
  • Sales
  • Tenant Management
  • Underwriting
  • User Management

We’ve completed a major technical upgrade of our .NET service stack to .NET 10. This brings your tenants onto a modern, fully supported runtime with better performance and long‑term security coverage. As part of this work we:

• Updated core policy, pricing, finance, migration and user‑management services,
• Adopted the latest Microsoft and EF Core guidance for compatibility and performance, and
• Modernised our automated test and code‑coverage tooling to keep quality high as we evolve the platform.

These upgrades are intentionally low‑risk and behaviour‑preserving for business workflows, but they provide a stronger foundation for future features and security improvements.

3. Regular security & dependency updates for .NET services

• Component: .NET platform / Tenant Management & shared services

As part of our ongoing security and reliability program, we’ve completed a new round of dependency and library upgrades across the Seamless .NET services. This includes:

• Updating third‑party libraries based on our security guidelines,
• Applying vendor‑recommended patches to database and messaging drivers, and
• Refreshing our local cloud‑emulation stack used in CI to better mirror production.

These changes are not visible in day‑to‑day usage, but they reduce exposure to known vulnerabilities and help us diagnose and fix issues more quickly across environments.

4. Automation pack for regression

• Component: Automation / Quality Engineering

We’ve extended our automated regression test suite with additional coverage from the December iteration. This gives higher confidence that existing policy, claims and administration flows continue to behave as expected when new changes are deployed, reducing the risk of regressions across all tenants.
