I believe thor occasional makes update threads to announce big updates and/or ask opinions. I don't know if they'll ever make a single thread that they add onto with updates like "added a bush to lvl 14" but it couldn't hurt I suppose.
Ok seriously now the only update of visible significance as opposed to adjustments to systems, utility + level resource classes is that the new spar arena class is pretty much complete and also implemented within SuperNicks, it has more features than previous arenas on the server, is mainly display based instead of controlled by chat commands, is designed to be re-useable and customisable.
This is something that I was going to make a thread for, as Gladius say's it's only big updates or situations where player opinions are felt to be required in order to add improvements that have been deemed worthy of posting here, while smaller updates may be posted within the server login PM.
