We're excited to announce a new release of SedonaDB, and this one is a big one! Between native DataFrame APIs in Python and R, a brand new Geography implementation, GPU accelerated joins, and a raster/ND-array foundation, it's hard to know where to start.

Seems like a big deal: "The headline feature of 0.17.0 is a new mechanism that keeps more of your query running inside Comet instead of falling back to Spark: the JVM codegen dispatcher."

My favorite Safari feature is how it auto-completes the URL you want to go to and then, mere milliseconds later, gets shy and removes the auto-completion, so my Google history is filled with a bunch of insane searches for two- and three-letter prefixes.
