Spring ’26 Release Architect Highlights: Security, Stability, and Agents
Summary
The Spring ’26 Release introduces major architectural changes focusing on security, stability, and AI governance in Salesforce environments. It mandates replacing legacy Connected Apps with External Client Apps (ECAs) to enhance security via modern OAuth flows and stricter access control. The release phases out legacy SOAP login methods and shortens certificate lifecycles, urging architects to audit integrations and update authentication to OAuth. It also formalizes governance layers for AI agents through the Agentforce DX Model Context Protocol, enabling secure AI metadata access. Additionally, new features like Apex Cursors improve large data processing, while Hyperforce expands data residency, providing tools to meet compliance needs.
Takeaways
- Migrate legacy Connected Apps to External Client Apps for enhanced security and governance.
- Update CI/CD pipelines to reflect restricted Connected App creation and use ECAs.
- Transition from SOAP.login() to OAuth authentication to avoid deprecated protocols.
- Implement governance using Model Context Protocol for secure AI agent interactions.
- Use Apex Cursors with Queueable Apex for efficient large dataset processing.
