New Features
The following features are new to Composer in this release.
Salesforce Review: Enforce PKCE & RTR Across Composer OAuth Flows
Salesforce is enforcing Proof Key for Code Exchange (PKCE) and Refresh Token Rotation (RTR) for all OAuth-enabled applications. To comply, the Conga Composer OAuth architecture has been updated. Version 8.298 is also compatible with the Salesforce Summer '26 release.
Why This Matters
On June 13, the package will be auto-pushed to your sandbox and production orgs. The running user will be prompted to "Allow" the new reduced OAuth scopes, after which all existing solutions will continue to work as normal.
- Note: Customers blocking Composer NA for Salesforce, Composer EU for Salesforce, Composer AP for Salesforce Connected Apps will lose access once their tokens expire. Please allow these Connected Apps to continue using Composer as intended.
- Known Issue: Composer SF1 mobile solutions will temporarily be prevented from generating documents. On June 13, a backend fix will be applied to resume all SF1 mobile solutions.
What Actions To Take
If your org doesn't receive the auto-push on June 13, please manually install the package by June 20. Salesforce will enforce these changes on June 21.
- Exclusion list customers: Please manually pull and install the new package by June 20.
