Octopus July Release 3.15

The July 2017 release of Octopus 3.15 introduces significant enhancements, including the integration of Let's Encrypt for automated SSL certificate management, facilitating a seamless transition to HTTPS for Octopus Server users. This update also addresses user feedback by allowing un-tenanted projects to be deployed to tenanted machines, enhancing flexibility in deployment scenarios. Improvements to the command-line interface include refined logging, error management, and the introduction of a --format=json option, along with deprecated switches ahead of Octopus 4.0, urging users to test automation scripts for compatibility. Additionally, a post-install data fix may require extra time, especially concerning the Events table, and users should follow standard upgrade procedures while ensuring the watchdog service is stopped during the process.
