Rust's December update is a big one. It's replacing the experimentation system for blueprints with something that's a bit more reasonable: a workbench-based tech tree system, so that you can always be working toward the items you want to craft.
As Rust creator Garry Newman explains in this week's blog post, the tech tree update is meant to address the fact that the random experimentation system has proven to be frustrating and costly. Under that system, players could use scrap to 'experiment' and gain a random new blueprint.
Now you'll be able to see the entire tech tree of items available from a workbench's tech level. That way, you can find the item you want and work toward it, without having to worry that your precious scrap is going to go to waste on a blueprint you don't need or want. New players ought to have a much easier time getting set up with useful blueprints from now on, rather than "having to pray to the RNG gods to find a SAP in a crate," as Newman puts it. Great.
