+///
+/// This file contains deprecations which have occurred in BlueprintLists, for which there are reasonable
+/// forward-moving defaults (eg, renames), to ease transitions for consumers when they update their library version.
+///
+/// To add new deprecations and changes:
+/// ------------------------------------
+/// 1) Add a new `MARK: Deprecated <Date>` section for the deprecations you are adding.
+///
+/// 2) Add deprecation annotations like so:
+///    ```
+///    @available(*, deprecated, renamed: "ItemContent")
+///    public typealias ItemElement = ItemContent
+///    ```
+///
+///    Or, when deprecating properties, add a passthrough like so:
+///    ```
+///    public extension Item {
+///       @available(*, deprecated, renamed: "content")
+///       var element : Content {
+///          self.content
+///       }
+///    }
+///    ```
+///
+/// 3) After 1-2 months has passed, mark the previously `deprecated` items as `unavailable`:
+///    ```
+///    @available(*, unavailable, renamed: "ItemContent")
+///    ```
+///
+/// 4) After another 1-2 months have passed, feel free to remove the `MARK: Deprecated` section you added.
+///
+
+//
+// MARK: Deprecated May 29, 2019
