- Delivery status notifications were displayed only for the first recipient
- Composing a message from a template with attachments failed because a temporary file was removed
- The size of attachments was no longer displayed in printed emails
- A message with multiple attachments sometimes sent only one attachment
- Thunderbird sometimes attached the wrong messages when multiple messages were forwarded by attachment
- Thunderbird no longer asked for an SMTP username if it was not specified
- Messages with BCC recipients filed in the Outbox did not keep the BCC header when moved to the Sent folder
- Thunderbird displayed reminders for canceled or declined appointments
- The "New feed account" dialog did not take dark mode into account
