Ghost Release: 5.49.2

TL;DR

Ghost v5.49.2: Email Service Debugging Enhancement

This minor release adds temporary debugging functionality to the email service to help diagnose issues with large recipient batches. When the email service encounters batches exceeding size limits, it now creates detailed data dumps to help the Ghost team identify and fix the underlying problems. This is a targeted maintenance release aimed at resolving specific email delivery issues reported by users.

Highlight of the Release

• Added debugging functionality to the email service to help diagnose issues with large recipient batches
• Temporary implementation that creates data dumps in the content/data folder when batch size limits are exceeded
• Targeted fix for reported email delivery issues with large subscriber lists

Migration Guide

No migration steps are required for this release.

Note that the email service debugging functionality is temporary and will create data dump files in your content/data folder when email batch size errors occur. These files contain diagnostic information to help the Ghost team resolve email delivery issues and will be automatically generated when needed.

Upgrade Recommendations

This release is recommended for Ghost users who:

• Have experienced issues with email delivery to large subscriber lists
• Are running email newsletters with large recipient batches (2000+ subscribers)
• Want to help the Ghost team diagnose and fix email delivery issues

The upgrade is optional for most users but recommended to ensure email delivery reliability, especially for sites with large subscriber bases.
