Unity 2017.4 is now available! Downloads and Release Notes Blog post This is a little different to our usual releases. We do not have any shiny new features to show off in 2017.4 - instead, 2017.4 marks the beginning of our Long Term Supported (LTS) programme for Unity 2017. The LTS version will not have any new features, API changes or improvements. It will address crashes, regressions, and issues that affect the wider community, such as Enterprise Support customer issues, platform SDK updates, or any major changes that would prevent a large section of users from shipping their game. We will be releasing updates for it, every other week, until early 2020. If you already have all the features you need from the engine, and just want a version you can rely on to finish shipping your project, then this is for you. As usual, we recommend you back up your project before upgrading - though if you are currently using Unity 2017.3, upgrading to 2017.4 should be just as easy as upgrading to a 2017.3 patch release. If you encounter any issues, please let us know by submitting a bug report so it can reach our developers. For more information on the LTS programme and why we're doing this, please see the blog post.
