Cakephp doesn't have a changelog file in the repository.
You can either browse trough the github versions for a short textual changelog: https://github.com/cakephp/cakephp/releases
Alternatively you can read the changes in the cakephp news: http://cakephp.org/pages/news
Or if you want see the granular changes you can browse the source code by tags: https://github.com/cakephp/cakephp/tree/2.6.6
