Update: I am finally done with step 5. All three scenarios from 1.17 are playable again, and all civilizations are in a state where I have given them a first pass and consider them playable. Of course, that does not mean that there cannot be further changes, but that they are ready to be played and I can get feedback for them.
That can happen after step 6 is completed. This step is not just a formality, so while short, it will take some time to complete. Most importantly, I will return to 1.17 one last time to address the issues reported for it. Then I will rebase the 1.18 work in progress branch on that 1.17 state (i.e. merge them) and promote that state of the mod to the develop branch shortly thereafter, making it available for everyone to play on. Conversely, that state of 1.17 will be the last state of the mod on the old map, any future updates and development will continue on the big map, which at that point will become the official map of DoC.
Around that time I will also post a full changelog for 1.18 on the forum. Lots of things besides the map itself have been changed during development, and while I have mentioned many of them on the forum at some point, I want everyone to have the full list to see what the differences are. I will also post a full list of all civilizations in the mod at that point. Many changes have been made so that almost every civilization has been touched. I think rather than listing all the differences to 1.17 it is more helpful to simply describe what the current state is.
After that, I will immediately continue development. Like I mentioned last time, the next step will be some changes to the civics in the game. I feel pretty good about my current plans for that so I am excited to get to it. More on that when the time comes.
Be on the lookout for more updates.
