REST API: Get Changeset 'Likes' returns 404

The REST API to return the list of 'Likes' for a given changeset seems to return a 404. Given the following example: https://bitbucket.org/api/1.0/repositories/thedillonb/testrepository/changesets/b88f296c63eb6c98bfdc2c2f44626b26222df21c/likes

Should return a list of User's according to: https://confluence.atlassian.com/display/BITBUCKET/changesets+Resource#changesetsResource-GETthelikesonanindividualchangeset

but it does not.
