Finally the release of OpenTTD 0.7.0 has come!
It brings you, amongst other things:

• Reworked order system (conditional orders, have both non-stop and via instead of one of the two)
• Ability to have much more engines
• Path based signals
• AI framework giving everyone the ability to write his/her AI
• Downloading of AIs and graphics from a central server (only when author wants to)
• Non-water map edges
• Initial support for right-to-left languages like Arabic and Hebrew
• Increase or removal of several limits: window size, number of windows, network clients (now 255), companies (now 15)
• Six new languages (Arabic, Hebrew, Indonesian, Latvian, Luxembourgish, Welsh)

Today we have released the second release candidate for 0.7.0. As usual the changes primarily consist of bugfixes and updating of the translations.
Will this be the last release before the 0.7.0 release? This and more when the next release is made.

Today we have released the first release candidate for 0.7.0. We hope this will be the last step before 0.7.0.

Today we have released the second beta for 0.7.0. It contains a fair number of bug fixes and a few small features. We hope you'll test this as thoroughly or even more thorough than 0.7.0-beta1.

Today we updated openttd-useful.zip as some vulnerabilities were fixed in libpng.
If you do not compile OpenTTD yourself or you are not using Microsoft's compiler you will not be affected.
