2021.1 Tech Stream for coders
The Tech Stream release is for creators who value exploring in-progress features to stay on the cutting edge. With our focus on increasing the stability and robustness of the Unity Editor, this release includes core Editor integration of graphics packages, visual scripting, the Device Simulator, and more workflow improvements.
More features to improve your coding workflow
Create logic with visual scripting
Visual drag-and-drop graphs supplement your code for faster prototyping and iteration. Visual scripting is also a great way to make existing scripts more accessible and create tools for use by non-programming team members.
Improved UnityLinker for faster, smaller executables
UnityLinker enhancements improve method body stripping, detection of C# reflection, and delegate stripping, all to reduce the amount of time IL2CPP spends converting the stripped assemblies to C++, as well as the executable size.
IL2CPP optimizations for better project conversions
This version of Unity comes with a collection of many small optimizations throughout the entire IL2CPP conversion and underlying C++ compilation to improve build time and project conversions.
Comprehensive memory profiling
Unity Profiler’s memory profiling package has been updated to ensure that all relevant data is reported for managed data types, including multi-dimensional arrays, as well as improving texture and mesh memory reporting.

In an effort to provide more clarity around package readiness and expected release date, better quality packages, and as a direct response to feedback from you, we’ve created a more rigorous process for labeling packages, as well as a new categorization system. Learn more here.
Both our alpha and beta releases are open to everyone, so no signup is required. Get started by downloading them from the Unity Hub. Because there may be feature-stability issues with these early releases, we do not recommend them for projects in production, and we highly recommend that you back up any project before you open it with an alpha or beta release.
