The main change in Redshift 3.5.24 is the built-in support for ray tracing acceleration technology on Apple M3 processors, available in the new iMac and MacBook Pros. Maxon describes the update as a "significant performance boost," although it does not provide a quantitative assessment of the potential speed increase.

Apple Silicon M3 processors are supported only for the primary GPU rendering engine of the final quality in Redshift, but not for interactive rendering using Redshift RT, which is designed only for Windows and NVIDIA. Among other changes mentioned in Maxon's blog announcing the update are improved interpolation in the ramp shader and a fix for a bug with stepped gradients.

The Houdini plugin has also received a number of improvements, including the ability to render regular and deep AOVs from a single ROP without reloading the scene. Changes have also been made to material overrides, allowing for multiple overrides for Redshift Proxy objects and overriding only surface attributes for scene objects without affecting displacement and bump input data, as shown in the image above.

Redshift 3.5.24 is available for Windows 10, glibc 2.17 and above Linux, and macOS 12.6/13.3 and above. Render integration plugins are compatible with 3ds Max 2018 and above, Blender 2.83 and above, Cinema 4D R21 and above, Houdini 17.5 and above (18.0+ on macOS), Katana 4.0v1 and above, and Maya 2018 and above. The software is available for rent only, with a subscription cost of $45 per month or $264 per year.
