I initially misunderstood this headline to mean the opposite: I took "drops" to mean "introduces", which is the opposite of the intended meaning -- "withdraws". Not sure where I got this non-mainstream meaning of "to drop".

#4The ULX3S is great! I built myself an early prototype a year ago, and have used it every so often for occasional hacks. It has since evolved to be a first-class citizen in a number of projects and frameworks (LiteX, including LiteDRAM), which makes it great to get started with.
Also worth noting, that you can use a fully open source flow (Yoys + nextpnr + prjtrellis) for this FPGA family. Here's a repository I made that shows a basic blinky for an ULX3S: https://github.com/q3k/ulx3s-foss-blinky/

People do talk about “dropping” an album to indicate it’s being released. Your confusion is somewhat understandable. English is hard. :(

#6Layman question: how many years before we get RISC-V desktops or Raspberry Pi like computers?

This is amazing!
But of course it would be even better if they would just publish the documentation.

#9very impressive project, its a good time to get into fpga projects

A developer of Symbiflow toolchain once described Lattice Semi as very friendly and cooperative towards them [1]. I was wondering why they suddenly changed their attitude. It may have been a clause that they introduced without giving much thought. Happy to see that at least one vendor has the right idea about tooling.
