Hello! We are getting ready to roll out Update 7 for Millennia, and we've made it publicly available for testing on our Open Beta branch on Steam.
If you haven't use our Open Beta before you can access it through the "Properties > Betas" settings for Millennia on Steam we have a forum here for Open Beta feedback as well.
UPDATE 7
Featured Changes
The main theme for this update is Polish and Quality of Life changes.
We've been working on some of these since before the launch of Atomic Ambitions, and some of these are new changes that we've been able to undertake now that we've had all hands free again.
The main things we're excited about are some long-standing feature requests from the community, as well as updating our Simultaneous Multiplayer out of Beta! (We're well aware that the announcement coming as part of an Open Beta update is somewhat ironic).
Grey is the same as before, Yellow uses the existing behavior (lock-in), and Red is the new behavior (lock-out & in).

The official Example for making Custom Map Types has been updated to reflect this. (Link to the Workshop page here.)

The new intermediate state preserves the current operation – it prevents assigned workers from being removed but allows new workers to be assigned to the Improvement.

Modding
- Added the ability to add custom map generators through mods.
- Map Generators are used to generate certain shapes of hexes when loading a Map Type. Create your own Generators for an even greater control over the map-making process!
- Custom Map Types had an issue that caused maps to change the location they are loaded from after being uploaded to the Steam Workshop. This was causing unforeseen differences to modded maps before and after upload. We have fixed this issue, but if you play or create Custom Map Types, please read the following...
- NOTE TO PLAYERS: As a result of this fix, existing save games on workshop-downloaded map types will no longer load and need to be started over. We never aim to damage existing saves, but this was a necessary side effect, unfortunately. We do not expect this to happen again.
- NOTE TO MODDERS: Existing Map Type mods on the Workshop will NOT need to be updated in order to be playable. However, the Map Type's Name and Description WILL need to be updated, as the previous Name/Description was dependent on the map's load location (and thus would break after uploading to the Workshop before anyway). Replacing "ExampleIslands" with the internal name of your new Map Type, the formatting looks like this now:
UI-MainMenu-MapType-ExampleIslands
UI-MainMenu-MapType-ExampleIslands-Tooltip
The official Example for making Custom Map Types has been updated to reflect this. (Link to the Workshop page here.)
