What's new

These are the most important features you'll get by upgrading from 2020.3.10 to 2020.4.9

Octopus 2020.4

Highlights

Better configuration file support for YAML, JSON, XML, and Java properties files, and built-in Worker Pools on Octopus Cloud for both Windows and Linux.

  • Better configuration file updates for Java, NodeJS, Ruby and more: is an update to our JSON configuration variable replacement support to make it even more useful. It now supports JSON, YAML, XML, and Java Properties files.
  • Octopus Cloud: Built-in Windows and Linux Worker Pools, and simpler dependency management. Octopus Cloud provides dynamic workers to execute scripts against your services and infrastructure. This update adds better cross-platform support with images for modern Windows and Linux operating systems. All Worker images support execution containers, which let you execute deployment work in isolation without the need to manage dependencies and containers.

Breaking changes

This release includes two breaking changes:

  • Deprecated our Azure VM extensions - We recommend using PowerShell DSC as a replacement. Our documentation covers this decision and links to further articles on how to achieve this with PowerShell DSC. See this article for instructions to accomplish this with Amazon Web Services as well.
  • Updated Deploy to IIS step - We have updated this step to remove support to deploy to Azure App Services. We recommend using our Azure support instead.
