Haze's post sums it best.

Although no newly supported working games, some significant updates over past few months includes prom support by Moogly which is needed for many of the non-cpu games that do use proms.

-netlist: Added 2716 16 Kbit (2 Kbit x 8 ) UV EPROM.
-netlist: Added 82S126 1K-bit bipolar PROM device.
-netlist: Added 82S126 4kbit (512x8) TTL bipolar PROM.
-netlist: Added 82S123 256-bit (32x8) TTL bipolar PROM.

Couriersud has also made lots of various improvements over past 5 months with one recent one in April.

Netlist code refactoring:
- more use of c++ features
- some CRTP in pfmtlog
- demangled code for truthtables
- use more constexpr
- rewrite main loop
- use default constructors and assignment operators were applicable.
- optimized 7448 and 9316

All of this has decreased startup time by approx. 25% to 30%. Complex
netlists like pong or kidniki are parsed, analyzed and constructed in
around 15 ms. Run performance has increased by about 5%.

All in all not to bad. A game like pong uses a clock of 7 MHz (after
division by 2). Thats 14 MHz clock invocations. Running at over 200%, 28
MHz. On a 3.9 GHz Machine about 140 cycles/clock change. [Couriersud]

A lot more ttl devices and more various prom support still needed before more complex non-cpu games can be supported and also some of the current ttl chips support still being improved along the way before other discrete based (audio hardware or video hardware) is emulated.
