Meteorologically it's now summer, and should the weather not agree with that, then now is a good time to update your OpenTTD version to OpenTTD 1.3.1. It's the first maintenance release in the 1.3 series. Additional to the changes as found already in the release candidate a possible crash when overbuilding reserved station tracks was fixed.
Should you stumble over any bugs or issues with this version, please report them.
Enjoy and happy building!
Your OpenTTD team
