After a long (but not long enough) development phase, I opened WebTranslator2 as a beta service. This means that everyone who feels enough courage to translate OpenTTD to her/his native language are welcomed to ask for a translator account. See details at WebTranslator2 home page [dead link].
Happy translating! WebTranslator2 was since replaced by Web Translator

A couple of screenshots have been added to the screenshots section.
It was pretty hard to find good screenshots so if you happen to have pictures that are just brilliant, don't be shy to contact me for addition to the above mentioned section.

Elrails has been merged into mainline, and can be found in the nightlies.
Electric rails adds a fourth rail-type to the game, enabling the realistic addition of electric engines, which, well, need elrails to operate.

OpenTTD 0.4.7 is a hotfix for the previous release. In this a nasty bug has crept, due to improper testing, that prevented the pathfinder (NPF) to work correctly. This greatly set back the gaming-experience so it was decided to do another release than to have you suffer from this.
"You can safely upgrade from 0.4.5 to this version as hopefully nothing has gotten broken, only fixed." <- I can confirm this though making it valid for 0.4.7.

As usual, you can find the release on SourceForge. There is also a forum post to spill your feelings, and a scenario package that you might want to use with the source files.

OpenTTD is back with a quick release. This time no new features only bugfixes. But at least this one is hot on the heels of 0.4.5 and should work more pleasantly. You can safely upgrade from 0.4.5 to this version as hopefully nothing has gotten broken, only fixed. Have fun.

As usual, you can find the release on SourceForge. The files are in the process of being uploaded and distributed so have a little patience when some releases are not found on SF.
