we're making a small post rendering change effective tomorrow at noon. in posts made before tomorrow at noon PDT, if you add image and audio attachments to the same post, the audio attachments always come last regardless of the order in which they're added; starting tomorrow, all the attachments will be displayed in the order you inserted them. this needed to be done in preparation for bigger improvements we're making to the editor soon, which we hope to start testing internally sometime this week.
