 ## [Unreleased]
+### Added
+- Add support for [Perspectives](https://www.sanity.io/blog/introducing-perspectives-sanity-previews) (https://github.com/balexand/sanity/pull/83).
+
+### Removed
+- (BREAKING) The `:drafts` option has been removed and passing it will result in an error. The `:perspective` option should be used instead. The default behavior is the same so breaking change will only apply if you are explicitly passing the `:drafts` option.
+
 ### Changed
 - (BREAKING) Switch HTTP client from `finch` to `req` (https://github.com/balexand/sanity/pull/81). This introduces the following breaking changes:
   - The `headers` field of the `Sanity.Response` now returns a map instead of a list of tuples. See https://hexdocs.pm/req/changelog.html#change-headers-to-be-maps for details.
   - The `:http_options` option for `Sanity.request/2` is now passed to `Req.request/1` instead of to Finch. The available options will be different.
-  - The `:max_attempts` and `:retry_delay` options have been removed from `Sanity.request/2`. `Req` handles retries for us.
