Upgrade from version 2016/02

[janspeksnijder]

I have installed the scripts from https://blogging.dragon.org.uk/wp-content/uploads/2016/02/dhcp_dns_changes_synology.tgz with the provided install script. This is an old version (2016/02).
The install script does extra the configuration of logrotate. In the current version there is no install script and not a logrotate configuration file (dhcp-dns).

Is it enough to follow the deployment instruction in README.md?
Do I have to remove all old files, inclusive the logrotate configuration file?

Hmm.. I'm not that familiar with the link you provided so I'm not real sure how they use logrotate. What I can say is that the install instructions listed here in Readme.md should work as is. Those instructions assume that there is no previous version installed. If you'd like to improve this and include things like logrotate, I'm open to a PR
