Do they still sell Stride?

Excuse me, I'm interested in learning more about the availability of Stride. I've heard some good things about it and I'm wondering if it's still being sold. Could you please provide me with some insight into its current status in the market? Are there any specific platforms or vendors where I can purchase Stride? Additionally, is there any new information or updates regarding its future development plans? I'd greatly appreciate any information you can provide.
