August 2, 2007 — The Ronja 10M Receiver, 10M Metropolis Transmitter and Inferno Receiver modules have been mechanically upgraded to use mounting brackets instead of the former bolts or cylinders with inner thread. The mounting brackets are made from tin plated steel sheet, solve several problems at once and are easily made.

August 6, 2006 — Twister2 has been released. It's now a part of Ronja Tetrapolis and Ronja Inferno. It is smaller, based on SMD components, and saves 1.4W of power. The electronic parts cost 30% more, but is much faster to build, because the mechanical design is greatly simplified. Twister2 was designed because someone complained about TV interference. Twister2 radiates 8x less residual energy than Twister.

January 14, 2006 — Sector marks have been added to the Twister PCB and Transmitter PCB. Sector codes are automatically generated into the population list. Thanks to this innovation, the location for an electronic part can be found instantly. This is expected to speed up Twister and Transmitter population and repair significantly.
