Are tags case-sensitive?
Tags in DigitalOcean used to be case-sensitive and preserved case on creation.
Recently (in the past week?) DIgitalOcean seems to be lower-casing every new tag. Is that a new, intended behavior? Is that documented anywhere?
You can easily see this behavior by going to the tags section of the Droplet and adding a tag with capital letters. It will be saved in lower case.
