FPGA for mid-density logic — what you get with the EP4CE55F23C8L
That means Intel is still manufacturing it, no last-time-buy notice, no end-of-life clock ticking. If you're comparing against the EP4CE40F29C8 (39600 LEs, 532 I/O in a different package), the EP4CE55F23C8L gives you more logic and a smaller BGA footprint — but the EP4CE40 is not a pin-compatible second source; each requires its own PCB layout.
