I created a script that automates updating your Sendy installation
Keeping your Sendy updated is something you should always look for.
I am sharing with you my script that follows the Sendy instructions and updates your installation to the latest version.
On top of the official Sendy instructions, it generates a ZIP backup of your current installation in case anything goes wrong and you need to revert.
The only thing you must do is to configure the variable for sendy installation and your license code.
The script takes care of downloading the new updated version for you.
