A new version of the release candidate for Bernd Gabriel's helpful work on merging the latest stable version of Standard into the latest version of Experimental is available here (http://bridgewater-brunel.me.uk/downloads/Simutrans-Experimental-RC.zip). This is just the Windows binary, but it should suffice for testing purposes.
It is based on the 10.18 release of the released version of Experimental, and also includes a number of bug fixes by Bernd since the last release candidate. I should be very grateful for all feedback/bug reports (please post a new thread for each report rather than adding them to this thread: please only post in this thread for general discussion about the release candidate, trouble with downloading, etc.).
Thank you for testing!
