 ## 1.40.0
 
+- We no longer trim starting newlines during assertions, allowing asserting
+  leading newlines match those in a snapshot value. Existing assertions with
+  different leading newlines will pass with a warning suggesting using
+  `--force-update-snapshots` to update a snapshot, and will fail in the future.
+  (Note that we currently allowing differing trailing newlines but may adjust
+  this in the future).  #569
+
 - `cargo-insta` no longer panics when running `cargo test --accept --workspace`
   on a workspace with a default crate. #532
