The 1.4.1-RC1 testing release still had a few bugs that were found due to your play-testing efforts. Among them an issue for multi-head train refits at stations, and an old bug where cargo was not aging. The entire list of changes can be found in the Changelog.

As usual, please test the new new 1.4.1-RC2 release, and report any bugs that you find to the FlySpray bug tracker.

If all goes well, we should have a new stable release soon.
