     Dialogue more closely follows the URI specification as defined in [rfc3986 section 3.3](https://datatracker.ietf.org/doc/html/rfc3986#section-3.3), and allows colons in http paths and query parameters.
 
+    Note that this is not an API break, however we're using a breaking changelog entry for visibility in case of unknown non-compliant servers.

     Previously the `:` character would be encoded as `%3A`, which is also allowed by rfc3986, however not required. Some server implementations, GCP APIs in particular, require colons in path strings not to be encoded.
     This encoding is an implementation detail within dialogue, where either way is valid for servers which are compliant with the rfc.
