Bug Fixes

Audio Card Link Fix

Fixed an issue where links to posts on audio cards in emails were broken. The bug occurred because the code was incorrectly trying to access a url property that doesn't exist directly on the post object. This was a remnant from an older implementation that serialized the model first.

This fix ensures that when subscribers receive newsletters containing audio cards, the links will properly direct them to the associated content.

New Features

Security Updates

No security fixes were included in this release.

Performance Improvements

Improved Mailgun Event Processing

The wait time between Mailgun events was initially increased from the default to 150ms, and then further adjusted to 200ms. This change reduces concurrency when the database is experiencing slower performance, preventing potential overload situations.

This adjustment serves as a temporary solution until a more permanent fix can be implemented, ensuring more reliable email delivery processing especially during high-volume sends.

Impact Summary

This patch release addresses a specific bug with audio card links in emails and improves the reliability of email delivery through Mailgun event processing adjustments. While the changes are relatively minor in scope, they have a significant impact on the user experience for newsletter subscribers who interact with audio content.

The audio card link fix ensures that subscribers can properly access audio content shared in newsletters, eliminating a potentially frustrating user experience issue. The Mailgun event processing improvements help maintain database stability during email sending operations, which is particularly important for publications with large subscriber bases.

These changes reflect Ghost's ongoing commitment to delivering a reliable publishing platform with particular attention to the newsletter experience, which has become an increasingly central feature for many Ghost publications.
