The team has been hard at work preparing 4.17 for public release, and we’ve just made the first Preview build available on the launcher. Get a first glimpse at what is to come in the full release including major updates to Sequencer, production support for Audio Streaming, and a new plugin for help with real-time compositing pipelines, Composure.
To get Unreal Engine 4.17 Preview 1, head to the Library section on the launcher, select “Add Versions” and choose 4.17 Preview 1.
For a more comprehensive list of what to expect in this build, head over to the post on our forums from Stephen Ellis. Remember, Preview releases are meant to provide a look at what is to come and are not quite production-ready. We encourage you to wait until the full release of 4.17 before upgrading your projects to this version of the engine.
