 ## [Unreleased]
 
+## [0.5.0] - 2024-05-08
+
+### Breaking changes
+
+The `shouldDoInterceptions` function now returns true: 
+- If `sessionTokenBackendDomain` is a valid subdomain of the URL's domain. This aligns with the behavior of browsers when sending cookies to subdomains.
+- Even if the ports of the URL you are querying are different compared to the `apiDomain`'s port ot the `sessionTokenBackendDomain` port (as long as the hostname is the same, or a subdomain of the `sessionTokenBackendDomain`): https://github.com/supertokens/supertokens-website/issues/217
+
+
 ## [0.4.0] - 2024-03-25
 - Relaxes dependency on `http` to be anything below `2.0.0`
