We want to upgrade our version of octopus deploy from version 4.0.10 to the latest version, is there any release notes / a list of breaking changes for each release that someone can point me to.
Also If you have any other advice/resources that you think would be relevant feel free to post below.
The only other advice I would offer is that as you are going to be upgrading through many versions, if possible, cloning your current Octopus Server would allow you to run through the entire upgrade with zero risk or downtime and be confident in the process.
I hope this helps, please let me know if you have any further questions.
