Comment alter allows changing values of a fields on a node through comments. The module allows selecting any field of the content type to be altered from comments unlike any other contributed modules present in Drupal. It can be used to create a full featured bug tracker, customer support, etc. The modules strives to integrate different modules like core's Node module to store the changes as new revisions and Diff module for displaying the changes made in a particular comment. At present the module is available for Drupal 7 only and thus we have this project to port the module for Drupal 8.
