A week after OpenTTD 0.4.6 you have witnessed the release of OpenTTD 0.4.7. You might remember the good old times of 0.4.0 and 0.4.0.1; well this is about the same.
However with the good part that nothing essential was crashing, only some pathfinder problems which were cause by a half-working hotfix for another serious problem. So therefore OpenTTD 0.4.7.
We hope not to go through this same procedure for the next release though :)
