I don't think much of all was accomplished since then, besides the usual tinkering. New projects mostly stayed in limbo, and expansion continued as usual (i.e. new fleshpits, more sods, etc).
Anton made a VOS(k)HOD weapon, basically a HEP that can have its output beam compressed to various degrees, proportionally increasing penetration. He then gave it to a science crew that is currently making strides in improving on his slapdash design.
Anton is designing a pair of next-generation combat ship classes, using multi-aperture X-Ray free-electron lasers, and an enormous gamma-ray FEL for primary weapons systems of the two respective designs. He'll be done in a week or two.
Anton has designed a cheap flight suit for planetary forces, based off advanced rechargeable batteries and electric ducted fans, but the design is stuck in Council limbo.
Some artifacts have been researched, most interesting one being the blueraditite from the planetoid mission, which is a super-efficient albeit super-radioactive battery.
Saint has been making new robots, suits, and robot suits - the Assault Suit (aka Battlesuit 2.0), the Heavy Robot Body (aka braincase-Battlesuit), the Badgersuit (aka Milnoplate MkIII), the Sharksuit (aka regenerating Civic Defenders Longcoat 2.0), and... that's probably it. He's been at the forefront of personal defense equipment lately.
Charles mostly spent time fruitlessly interrogating Leo.
I probably missed a few developments here and there.
