Mod Organizer: vanhemmat versiot ja versiohistoria

Windows 10 1809+ or Windows 11 are now required due to the upgrade to Qt 6 and Python 3.11.

Unfortunately, MO2 cannot support Windows Store / Gamepass versions of supported games. The virtual filesystem is simply incompatible with the way the games are packaged.

For version 2.5.0, the installer will wipe any third party plugins as very few from 2.4.4 will be compatible with 2.5.0. If you've already installed a 2.5.0 beta build, I'd recommend simply overwriting the files using the archive download.

For older MO2 versions, a clean install is highly recommended if you do not use the installer as leftover files from 2.4.4 can and will break parts of 2.5.0 in addition to leaving old, extraneous files in the MO2 directory. You can migrate old portable instances by copying the mods, downloads, profiles, overwrite directories and modorganizer.ini file to the new install. If you use any third party game plugins, it is highly recommended to wait for an update before loading those instances.

Category Revamp
The default categories and Nexus category mappings are no longer hard-coded. When you create a new instance or load an older instance, you will be prompted to import and map the Nexus categories. You should be able to preserve your old categories if you had custom categories configured or use the old default mappings.

The updated category editor has a new interface to import the Nexus categories. These categories can be mapped to your custom Mod Organizer categories or imported. Importing the categories can replace or merge with your existing category setup.

In addition, you can automatically reassign categories based on your Nexus mappings using the right-click context menu or through the modlist dropdown action menu. For users updating from older versions, we can only map the category if you still have downloads with Nexus metadata available. As you install or update new mods, the Nexus category ID will be saved to the mod info as well. Mods without a valid mapping should be left untouched.

Finally, when you install a download from the download pane, missing mappings will trigger a prompt to update your Nexus mappings. You can also disable this feature entirely. This can be changed at any time from the Settings pane.

Python Plugin Updates
Python and Qt have both been updated to newer versions and Boost Python has been replaced with pybind11. These changes necessitate that most Python plugins be updated to be compatible with 2.5.0. On the other hand, you can now use Python 3.11.x features.

Basic Games
The basic games game support plugin system has had multiple updates to add and improve support for various game platforms, including EA Games, EPIC Games, and more. There are new utilities you can use to build more robust game plugin support with Python.

Game Support
Starfield
Starfield has full support with some general caveats. This includes save parsing, archive extraction and packing, plugin management, automatic archive invalidation, INI-enabled plugin and archive detection. This support virtualizes both the My Games Data directory and the game Data directory. This provides maximum mod support with minimal work needed by the end user. MO2 will create the Data directory in My Games, but due to the nature of the virtual filesystem, no files will actually we written to or read from this directory. This also allows SFSE plugins to be correctly loaded from the game Data directory.

Caveats
Plugin management is only possible by using the Plugins.txt Enabler mod. This can be loaded either with SFSE or an ASI loader. If you use the ASI loader you may want to disable this check. You must also remove any sTestFile entries from your game INI files.
BSA Packer currently does not support the newer Starfield archive formats and will pack files in the Fallout 4 BA2 format. This appears to work just fine and we will update to use the Starfield archive formats as soon as we can.
The BSA extractor has some trouble with archives containing 

- Fixed discord invite
- Removed Mass Effect support
- This was really only meant for WJ support which probably won't even be happening and people got way too excited about something that doesn't really work.
