This plugin is no longer being maintained. The original maintainer is not interested and no one has full permissions to this repository. A few of us have permissions to approve PRs and perform releases, but its time to begin moving the userbase over to https://github.com/dereuromark/cakephp-audit-stash
A successor is being maintained by @dereuromark who is a CakePHP core developer. Many of your are probably familiar with him. I have migrated my application to version 0.3.1 https://github.com/dereuromark/cakephp-audit-stash/releases/tag/0.3.1 which is compatible with version 4.2.2 of this project.
Simply replace lorenzo/audit-stash with dereuromark/cakephp-audit-stash:^0.3.1 in your composer.json file.
The original project README is available at README.old.md
