** The maximum file size of sent attachments is 5 megabytes on v1.1, v1.2 and master. This is done because we are likely to crash if we try and send larger files. {{bug|871897}} is about us switching to streaming for sending which would allow us to remove our send-side limitations. Receiving servers may still enforce a size limit. v1.0.1 has no size limit, but is likely to crash if files larger than 5 megabytes are sent.
* Attachment types supported
