What is log file ?

A changelog is a log or record of changes made to a project, such as a website or software project, usually including such records as bug fixes, new features, etc. Some open source projects include a changelog as one of the top level files in their distribution. http://en.wikipedia.org/wiki/Changelog

Example :https://github.com/phalcon/cphalcon/blob/master/CHANGELOG

We didnt use CHANGELOG file in development

To know changes I suggest you to monitor http://blog.zephir-lang.com/
