February 2025 Summaries

The new logs histogram in the Courier dashboard provides a real-time visual overview of message activity, making it easier to diagnose issues and track trends. With this feature, users can instantly spot spikes in failures or drops in message volume, zoom into specific periods for further analysis, and view an instant visual overview of message activity over time. The histogram offers a more secure way to authenticate AWS SES using IAM Role authentication, eliminating long-term access keys and reducing security risks. Additionally, Courier customers are unaffected by Apple's APNS Security Update, which requires updated server certificates starting on March 29, 2025. Users can send up to 10,000 notifications every month for free with the Courier service.

Amazon Simple Email Service (Amazon SES) authentication has been updated to support IAM Role authentication, offering a more secure and simplified way to authenticate without long-lived access keys. This method reduces the risk of credential leakage and simplifies credential management by using temporary, automatically rotated credentials. Courier now supports this new authentication method, aligning with existing security practices in AWS infrastructure. The update enhances security with temporary credentials and simplifies credential management, making it an ideal option for teams prioritizing security and operational efficiency.

Firebase Dynamic Links (FDL) will be fully shut down on August 25, 2025, causing disruptions for developers who haven't migrated to an alternative solution. The deprecation of FDL means that developers need to rethink how they handle deep linking across multiple platforms and communication channels. To avoid disruptions, teams must explore and implement new deep linking strategies before the deadline. Developers can transition to platform-native links, third-party providers, or a custom solution, taking action before the shutdown date to prevent broken experiences and lost user engagement.
