Hi everyone!
Only a few hours after we had finished testing and building 7.15.2, a critical bug was reported to our support. Here comes XP 7.15.3 with the fix.
The bug is about problems sending e-mail with attachments, especially large ones. A race condition appears when sending an e-mail with an attachment of a certain size, which may block the thread processing the attachment. How large the attachment must be to trigger the condition depends on other factors in the system, but we have recreated the bug with files as small as 10kb. This bug is present on every XP version from 7.14.1 to 7.15.2.
If you are a cloud customer and affected by this bug, please reach out to get an upgrade as soon as possible.
Here is the changelog: Release Enonic XP Distro 7.15.3 · enonic/xp-distro · GitHub
