Salesforce Winter ‘27 Release: What to Expect and How to Prepare
Summary
The Salesforce Winter ‘27 Release enforces important updates that affect key platform behaviors like email verification, accessibility, profile visibility, OAuth security, and tax calculation in Order Management. Admins and developers should proactively prepare by testing changes in Sandbox environments, refactoring customizations, and updating integrations to align with new security and functionality standards. The release advises configuring authorized email domains, enabling accessibility enhancements, applying profile filtering, retiring insecure OAuth flows, and validating tax rate calculations to ensure smooth operations post-release. Planning deployments outside core hours and having rollback strategies are key to minimizing user impact.
Takeaways
- Configure Authorized Email Domains for bulk user email updates after Winter ’27.
- Test accessibility enhancements at 200%+ zoom and adjust custom components accordingly.
- Refactor metadata to comply with Profile Filtering or grant View All Profiles permission.
- Migrate integrations from OAuth Username-Password Flow to more secure authorization flows.
- Validate tax rate calculations in Order Management processes using provided APIs before deployment.
Winter ’27 is approaching, bringing with it several Release Updates that will be enforced. These updates can change how existing functionality behaves, so it’s important to prepare in advance to avoid any disruption. Enforcement will be from September 2026, so ensure you review and test impacted areas ahead of this date to minimise risk and maintain a smooth user experience. Preparation When preparing for these updates, you can take one of two approaches: clicks-not-code (no-code) or pro-code. If you have a more developer-focused skill set, tools like SFDX (Salesforce Developer Experience) can give you a strong head start. By creating a local copy of your Salesforce metadata, you can more easily search for and identify impacted references. You can also use third-party tools such as Workbench or Salesforce Inspector Reloaded to run queries and uncover dependencies within your org. Finally, keep in mind that Salesforce may adjust release updates over time.
