I'm a big fan of Atlassian as they are an incredible Australian success story.

It also helps that JIRA and Confluence are my favourite collaboration tools which I use at work and so much better than email! Now that it's free, I can use it at home as an alternative to my other collaboration tools such as Google Drive, Docs, Etc…
I'm surprised nobody has posted this given the popularity of the JIRA deal just over a year ago https://www.ozbargain.com.au/node/401876
Enjoy… Free Forever!!!
Mod: Free since Sep 2019: "Atlassian adds free tiers for Jira and Confluence". Therefore marked as long running deal, this cannot be reposted in the future.
Completely off topic but we have been using not and azure DevOps at work and find azure DevOps a much more mature product. It's weird Microsoft don't have a confluence competitor but that's probably because it would canabilise o365.
