Recently, AMD launched several new Ryzen 5000 and Ryzen 4000 processors, half a dozen in total , perhaps to better compete with Intel's mid-range and low-end Alder Lake-S offerings. Aside from these, Team Red is also launching the Ryzen 7 5800X3D on April 20th when it will be going head-on with Intel's upcoming Core i9-12900KS.
AMD has also made old socket AM4 customers happy by announcing support for Ryzen 5000 series, including the new chips, on 1st gen 300-series chipset motherboards. The company was already contemplating on that for a while and it's possible that the Alder Lake pressure swayed AMD to do it, despite perhaps a few challenges.
However, there was still confusion regarding the support as accompanying announcements from Gigabyte and Asus had no mention of support for the popular B350 chipset. Andreas Schilling from Hardwareluxx reached out to Asus regarding the matter and the company has responded seemingly confirming that support for B350 is also coming at the same time as X370 and A320.

However, Asus has still not given the green light for the Ryzen 5 5500 SKU as the model is held back by a BIOS code limitation put in place by AMD itself.
