The mountains should now be glitch-free, so they are safe to conquer by train, road vehicle, aircraft, and even by ship! In addition, improvements were made to zoomed guis, for more fun at the high resolution screens.
There are other features and fixes too, for the full log, see the changelog. If you are more interested in playing, download here.

The new beta is just perfect for checking out the results of the title game competition, after looking at the screenshots and sending in your votes.

Have fun climbing the mountains,
The OpenTTD team
