New Year, but no new Version yet?
Simutrans' last stable release has been in May, last year. There are two reasons for the long delay. Firstly, with 112.3 the game was brought to a rather stable state with not many bugs affecting play. This is the base for several projects that change the game on a very fundamental level. Which is the second reason: The projects that are being worked on are quite large and need a lot of hours of coding and testing.
Very large projects are the new landscape patch, that allows a finer grained terrain, with slopes of two different inclines. So you can find for example a short steep route over a mountain ridge for a road or narrow-gauge railway. A regular gauge railway would have to take a route that is less steep. This patch naturally involved all aspects of the game. From the very base of maps, to all build tools. In code it is mostly finished for several months now. It is also very thoroughly tested. There is a very large workload on the graphics artists now to draw all the missing images for the pak-sets. Imaging hundreds of bridges, roads, retaining walls and so on.
Another patch with many dependencies is a complete rework of the graphical user interface (GUI). This project encountered a couple of communication problems between core developers and a new coder who enthusiastically started the very large project.
Not to be overlooked is a smaller project, the translation of german in the source code and comments to english. So far most developers had to code with a dictionary on their lap, unless they knew german already.
The devs are growing less comfortable with the state of flux at the moment, and started to wrap things up, for a release. It is good to have a stable and common base when developing new pojects to prevent bit rot
and unforeseen side effects and dependencies. Why are there no beta-releases?
Simutrans usually releases only full versions, and at some point release candidates, that are feature complete. However, the nightly builds (regularly compiled snapshots of the development version) are publicly available. Users who know their way in their operating system can install those, and also nightly builds of the pak-sets, to try out new features. Bear in mind however: things might change and break compatibility with your savegame, or might be buggy and break your game.tl;dr:
project still alive, lots of work, large new features to come, nightly versions are available #simutrans
