Hipster is a codename for rapidly moving development branch of OpenIndiana and users might experience occasional breakages or problems. Hipster is using rolling-release model and only publishes installation ISOs once in a while. Every ISO release will be announced via mailing list and Twitter.
Before considering using "hipster", please read the statement below.
Even though, hipster might contain some newer packages it is generally not advised for installation, which need some level of stability such as servers or fully functioning desktop. Things might break and could cause system/service downtime. Do upgrade only if you know what you are doing. You have been warned!
Updating to the Hipster branch on an existing /dev installation is not supported at this time. The recommended action is to backup your data and reinstall from hipster install media.
