Variables are now written in {braces}

Variables on a pass are now written in curly braces, such as {name} or {member_id}, the same way across the builder, CSV uploads, the API and integrations. Text written the old @name way is now treated as plain text.

Every existing pass was converted for you, so you don't need to change anything. If you type @name on a new pass, the builder suggests the braces version.
