Mod Organizer 2 Changelog

v2.5.2

Starfield Creation Support

Various fixes and improvements for compatibility with the Starfield Creation update.

Added new core plugins to the primary plugins list
Utilize Starfield.ccc to 'fix' the load order of core plugins
- By default, Starfield now loads core plugins after plugins.txt unless required by a dependent plugin
- This forces the plugins to a default early load order, making the plugin memory addressing easier to predict and less prone to unintended record conflicts
- The file is written to the active profile and virtualized to the game and My Games directories
Removed various now-irrelevant checks
- Plugins.txt Enabler is obsolete
- Light-flagged plugins no longer generate warnings
- Remove overlay-flag checks until such time as they actually become relevant
Added support for new 'medium'-flagged plugins
- These use FD memory addresses which will display in the plugin list
- A warning will display if a plugin has both a light and medium flag in the header as this could indicate record reference corruption and could break the game
Added creation kit to default executables
Updated save parsing to handle the newer save format
Added support for Creations parsing from ContentCatalog.txt
- Creation mods pull both names and file lists from the content catalog
BSA Packer now supports Starfield archive formats
- Dummy plugins are now saved as light-flagged ESMs
LOOT support is now automatically enabled with the addition of libloot 0.23.0

Bethesda Game Updates & Fixes

Add detection for Skyrim VR light plugin support SKSE plugin (#29)
Allow TTW to pull Nexus categories from FNV
- Still need a better solution for categories from secondary game sources
Allows previewing and parsing the new BA2 versions of Fallout 4

v2.5.0

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 numerous directories. Most archives are fine but you may experience extreme load times with the meshes / geometries base game archives due to them containing hundreds of thousands of individual directories.
Due to the nature of the game engine, only ESM files have relatively decent support and using another plugin type will generate warnings to describe the issues with using those plugins.
All Starfield diagnostic warnings can be disabled.
LOOT sorting is currently disabled by default as the LOOT team has decided that the issues with the engine make sorting too problematic. You can enable sorting in the Starfield settings. This could be useful if a future libloot / LOOT update allows sorting and can be hotfixed in MO2.

v2.4.0

Collapsible separators

Huge thanks to Holt59 for implementing everything here!

New feature: collapsible separators!

Enabled by default when sorting by priority (ascending or descending).
- Disabled when grouping by something else (Nexus ID or Category).
- Disabled when sorting by any other column.
- Can be globally disabled in the settings (Mod List tab).
Mods under separator are not indented on purpose while using collapsible separators.
When a separator is collapsed, it will visually reflect its children (most of these can be disabled in the settings):
- The marker on the scrollbar will take the color of the children markers (combined).
- The background of the separator will take the color of the children markers (combined).
- The icons in the conflicts, content, flags and version column will reflect information from the children (combined).
- Selecting a collapsed separator will highlight plugins and markers as if all the mods inside were selected.
When using collapsible separators, the 'Filter Separators' box in the filter list is disabled.
Shift+Enter on the mod list will now expand or collapse the current item or its parent when possible (with collapsible separators or in group by).
Alt+Click on a separator selects the separator and all its mods (even if collapsed).

New Game Support

Mod Organizer now comes with support for a couple of new games:
- Cyberpunk 2077

- Kingdom Come Deliverance
- Mirror's Edge
- Mount & Blade II: Bannerlord
- No Man's Sky
- STALKER Anomaly
- Stardew Valley
- The Binding of Isaac: Rebirth
- The Witcher 3: Wild Hunt
- Zeus and Poseidon
Support for these games is still preliminary. Some parts of the user interface might show elements that are unused by the game.
Adding basic support for a new game can be as easy as filling in an INI file now. See https://github.com/ModOrganizer2/modorganizer-basic_games if you are interested.
Many thanks to Holt59 for his hard work on the infrastructure to support these non-Bethesda games, as well as erri120, EzioTheDeadPoet, Qudix, Silencer7111 and Syer10 for creating plugins for some of the games.

Performance

Comes with buttons to explore the paths of an instance and opening the modorganizer.ini file.
Instance deletion will now support deleting customized instance paths such as base directory/mods/downloads etc.
Users can now select which paths to keep or delete.
Instance creation comes with a new wizard like setup to choose the game, define paths and optionally log into nexus.

Mod list

Improved mod conflicts tab labels and tooltips.
Drag&Drop:
- The UI should reflect more appropriately invalid action, e.g. drag&drop while not sorting by priority or trying to drop a file in an invalid mod.
- The drop indicator now span the whole row instead of only the column.
- With collapsible separators, you can drop onto a separator (collapsed or not) and the mod will drop at the end of this separator.
- New drag&drop features:
  - You can now drag&drop from the download list to the mod list to install a mod at a specific priority.
  - You can now drag&drop external archives to the mod list to install a mod at a specific priority from an external file (only if the file is supported by MO2).
  - You can now drag&drop external folder to the mod list to copy them.
Page Up/Page Down can be used to go to next or previous mod in the information dialog.
Improve robustness of the mod list regarding priority.
Add context menu entries to send selected mods before first or after last conflicting mods (#697).
The "Install mod" context menu entry will now install the mod above/below the selected mod when sorting by priority (#1369).

Download list

Added "Open meta file" right-click option to Downloads tab (Thanks erri120).
Add keyboard navigation to the download list (#924):
- Install selected mod: Enter
- Remove selected mod / cancel download: Del
- Pause / resume download: Space
When deleting a download, the filename is now displayed in the confirmation dialog (#1345).
Searching downloads now checks all the columns, added regex support.

Settings

The settings have been re-organized:
- There is now a "Theme" tab where you can change MO2 global theme and colors.
- All mod list related settings have been moved to "Mod List".
- The "Steam" tab has been removed and its content moved to the "Workarounds" tab.
- Non Nexus-related settings have been moved from "Nexus" to "Workarounds".
- Old unused settings have been removed: hide unchecked plugins and load mechanism.
The "Plugins" tab of MO2 Settings has been improved.
MO2 plugins that cannot be used with the current game cannot be enabled.
A confirmation dialog is shown when trying to disable plugins that are required by other plugins.
Added option for using custom browser to open links.

Command Line

Overhaul Mo2 command line with new commands and options(backwards compatible with current stuff):
- crashdump: replaces the old --crashdump.
- refresh: causes the currently running instance of MO2 to refresh.
- reload-plugin "A Plugin": causes the currently instance of MO2 to reload the plugin named "A Plugin".
- run ...: use to run a program, file or a configured executable. See run --help for more information.
- --pick: forces MO2 to show the select instance dialog on startup.
- -i <instanceName>: overrides the instance to open.
- -p <profileName>: overrides the profile to open.
- --multiple: allow running a new MO2 process even if other MO2 processes are already running.
- Warning! --multiple is unsupported and can create all sorts of weird problems. To minimize these:
  - 1. never have multiple MO processes running that manage the same game instance;
  - 1. if an executable is launched from an MO process, only this process may launch executables until all processes are terminated;
  - 1. it is recommended to close all MO processes as soon as multiple processes become unnecessary.

Archive distribution

Starting from Mod Organizer 2.4.0, we decided to only distribute the archive version of Mod Organizer on GitHub. See https://github.com/ModOrganizer2/modorganizer/issues/1191 for the reasons. The installer can be used to do everything that was possible with the archive version.

To upgrade an existing MO2 installation, simply point the installer to the existing MO2 installation folder.
To upgrade an existing MO2 portable instance, simply point the installer to the existing MO2 instance folder.
To create a new portable instance, point the installer to the location you want for the instance and choose "Portable Instance" when starting MO2.

The archive is only provided for automated new installations, such as the Wabbajack ones, and expert users. We will not provide support for archive installations anymore on the Discord server.

v2.3.2

Installer

Exclusions are automatically added to Windows Defender for:
- Mod Organizer's installation folder
- ModOrganizer.exe, usvfs_proxy_x86.exe, usvfs_proxy_x64.exe and nxmhandler.exe
- The default instance folder C:\Users\username\AppData\Local\ModOrganizer
The plugins and stylesheets folders won't be deleted any more when updating

Fixes

Plugins would sometimes be deactivated, along with errors like "invalid plugin priority" or "Plugin not found"
Skyrim VR would always report that the file structure "does not look valid" when installing mods
Installing mods from split archives would hang

v2.3.0

Performance

A lot of effort has been put into improving performance of MO2, especially startup, mod installation and general refresh (after a program is run or after pressing F5/Data tab "Refresh"). The speedup should be immediately evident for any sizable setup.

New Data tab

New columns: file type, size and date.
Supports sorting, searching, icons and tooltips.
Context menu: expand/collapse all.
Shell menu on shift-right-click (the standard Explorer context menu):
- If the selected files are all from the same mod, shows a single menu for that selection.
- If there are multiple origins, shows separate shell menus for each with warnings if some files are not present in all origins.
- Files must be in the same directory.

Mod info window

Search boxes in the General conflicts tab.
Added .json, .log and .toml to the "Text Files" tab; moved .cfg from "INI Files".
The window will remember the last opened tab when double-clicking the mod name column. Other columns will still open a specific tab and override the last opened tab.
Improved BBCode handling in the Nexus tab.

Mod list

Better management for Hidden Files:
- New icon and modlist filter for active mods containing hidden files.
- New "Restore Hidden Files" context menu option on the modlist.
New filter "Contains Optional Plugins".
Added some context menu options to mod backups ("Visit on Nexus", "Open in Explorer", etc.)
Shift-double-clicking on mods will open the custom URL if one exists or the Nexus webpage for this mod.
The list of filters now uses colored three-state checkboxes.
The Notes column can now be colored. Right-click the column for a particular mod and click "Select color" to change its background color.

Miscellaneous

New Turkish translation (thanks Nyks45!)
Columns in the Plugins and Data tabs can now be turned on and off.
All lists now use alternating row colors.
When installing a mod, moved the "Manual" button to the far left to avoid confusion.
The LOOT report window is now resizable.
Log window: smaller minimum size, added "Open logs folder" context menu option.
The search boxes in the Data tab and the various tabs in the mod info window now support regular expressions and other options. Right-click the box to enable them. This feature will eventually exist for all search boxes.
Added a confirmation dialog when clicking the Sort button in the Plugins tab

Plugins

New BSA preview plugin: the content of BSA files can be previewed from the Data tab, Filetree or Conflicts lists by right-clicking and selecting "Preview". This will open a window showing the files contained in the archive.
New C# FOMOD installer that replaces the NMM one by default.
Added an extension blacklist in the Preview Base plugin. This is used to disable previews for specific image or text file types. The blacklist is a comma-separated list of extensions without dots.

Fixes

Custom URLS won't be overwritten when reinstalling a mod.
Stopped notifying for updates for optional and miscellaneous files when only the main mod is updated.
Unmanaged mods were considered valid targets for "Create files in mod instead of overwrite" in the executable settings.
Some pictures were not displayed properly with the FOMOD installer.
Plugins from mods in junctioned folders were not activated properly.

For MO2 plugin creators

Greatly improved the capabilities of Game Plugins to allow support for other games:
- They may now define if a mod looks valid (for installation and modlist check).
- They can also define mod contents icons and filters.
- MO will no longer crash when GamePlugins (pluginList) feature isn't implemented.
- A generic game plugin example is available. Visit the MO2 discord for more information.
- Many thanks to Holt59 for a major rework of the various game plugins.
Python plugins can now be installed in their own separate folders.
Stubs are now available for the python interface (https://github.com/ModOrganizer2/mo2-pystubs-generation).

- Can set a custom color as background for viewing transparent textures that aren't easy to see on a traditional checkerboard background.
Added portable instance lock.

Added new lock dialog.
- Locks the GUI while being more flexible. Allows the user to resize the window, minimize the window, etc.
Added new options dialog.
- Displayed when the user needs to make a choice with multiple options and outcomes (e.g., starting the game but Steam isn't running).
- Provides a better explanation of each option as needed.
- Allows users to more easily tell the dialog to remember previous choices (instead of checkboxes).
- The details expander can provide more details.
Added new error dialog.
- Displayed when something goes seriously wrong (i.e., USVFS fails when starting the game).
- Provides human readable messages instead of esoteric error codes.
- Provides troubleshooting steps for common problems.

New Features

New Nexus Mods API support. This touches almost everything concerning connections to the Nexus. Downloads, update checks, endorsements, ...
- You must reauthenticate within the Settings Nexus tab
  - You no longer enter user credentials, instead you will see a button. Click this button and you will be redirected to Nexus where it will ask you to log in and then authenticate the request for MO2. Once this is done MO2 will automatically receive and store your API key. If you revoke this key on Nexus, you will need to click the button to revoke your local credentials and then request a new key.
- Requests are (currently) limited to 2500 a day and 100 per hour. (They are consumed simultaneously.)
  - Your currently remaining requests as well as the count of currently queued requests are now displayed at the bottom of the Mod list. This counter may be hidden in the settings.
- Nexus credentials are now stored in the Windows Credential Manager instead of in an INI file.
- Probably lots of other stuff.
Added support for Forced Loading Libraries.
- See https://github.com/ModOrganizer2/modorganizer/wiki/Running-Oblivion-OBSE-with-MO2.
Added support for Enderal: Forgotten Stories on Steam.
Added ability to check for invalid file attributes that may prevent a game from seeing the files.
- Will be run any time an external executable is run. Mostly relevant to Skyrim SE and FO4.

Added "active" counters to the top-right of the mod list and plugin list.
- Click or mouse-over the counters for more information!
Added archive parsing and conflict detection feature.
- This is still considered an experimental feature. Please report any bugs on the Discord server.
- Disabled by default. Check Settings > Workarounds > "Enable parsing of Archives" to enable.
Added the ability to track and untrack mods.
- Similar to the endorse mod feature. Indicated with a push pin in the flags column.
Added "Explore Virtual Folder" option in executables list.
- This launches a bundled instance of Explorer++ in the game directory. This can be handy to view files in their natural habitat and copy files out of the virtual file system.
- DO NOT try to move, delete, or create files through Explorer++. It probably won't work too well, if at all.
Added notification plugin to check for common script extender errors like using the wrong version of files (kudos to AnyOldName3).
Added protection against invalid "start in" directories for executables.
Added the plugins that are missing masters to the missing master notification.

New Features

New installer!:
- All MO2 files are downloaded with the installer. No more errors about being unable to download MO2 files.
- External dependencies like Microsoft Visual C++ 2017 Redistributables will be downloaded and installed as needed.
- The default install path is now "C:\Modding\MO2" in order to avoid UAC issues with portable instances.
- The installer will remember your previous install path in future automatic updates.
Added separators for the mod list:
- To create a separator, select the "create separator" option next to the "create empty mod" option in the mod list context menu.
- Custom colors may be assigned to separators by right-clicking the separator and choosing the "select color..." option. Separator colors will be displayed in the mod list scrollbar to help you find them.
- Custom colors may be removed from separators by right-clicking the separator and choosing the "reset color" option.
- Collapsible Separators are planned but pose some significant implementation difficulties, so it might take a little longer for this feature to arrive.
Added new FNIS automatic integration tool by AnyOldName3:
- Accessible from the puzzle (tools) icon on the top bar.
- You can configure the patches you ned once and then automatically generate FNIS files with just one click.
- Allows you to select a mod where to output the FNIS files.
- WARNING: If you have GenerateFNISforUser.exe configured as an executable, disable the "Create files in mod instead of overwrite" option.
Added "send to" functionality to the mod list and plugin list context menus:
- Selecting "top" or "bottom" will send the mod or plugin to the top or bottom of the list.
- Selecting "priority..." will allow you to set a specific priority for the mod or plugin.
- Selecting "separator..." in the mod list only will allow you to send the bottom of a section as defined by your separators.
Added executable blacklisting. This prevents executables from being hooked by the virtual file system. This can be used to prevent situations where a random program, e.g. Steam.exe, is hooked after running an executable.
- This option is accessible in the workarounds settings with the "Configurable Executables Blacklist"
- The default blacklist contains these programs: Chrome.exe, Firefox.exe, TSVNCache.exe, TGitCache.exe, Steam.exe, GameOverlayUI.exe.
Added a notes column to the mod list:
- The data in this column can be set in the mod info dialog (double-click the mod) in the Notes tab. The top entry field will be shown in the column. The bottom entry field will be shown in the tooltip you get when hovering over the column.
- This column is hidden by default. It may be shown by right-clicking the column headers in the mod list (Mod Name, Priority, etc.) and checking Notes.
- WARNING: The notes column will appear to the right of the priority column. You'll probably have to scroll over to see it.
Added support for .modgroups files. They will be shown in the contents column, the flags column, and are an allowed top level game data file.
Added refresh button to downloads tab.
Added "Contains Script Extender Files" filter to report any mods with a script extender folder (no DLLs required).

Added window geometry memory (size, shape, etc.) for many dialogs and windows.
Added the ability to reset window geometry memory in the workarounds settings.
Added the ability to customize the color of conflict highlighting and plugin hightling in the general settings. This is especially useful for users of dark themes.
Added the ability to prevent locking the MO GUI when running an executable. This option is available in the workarounds settings by clearing "Lock GUI when running executable".
- WARNING: Disable this setting at your own risk.
Added keyboard shortcuts for the mod list and plugin list name filters. Ctrl+F will select the filter. ESC will clear the filter when the filter is selected.
Added the following community themes:
- VS2015 variants and Skyrim, courtesy of chintsu!

- Transparent variants (101 Green, BOSS, Skyrim), courtesy of Gernash!
- Updated Paper Dark and Paper Light themes, courtesy of 6788-00!
Added dialog that appears when the virtual file system fails in a way that no logs are generated.

Added the ability to change the path to the managed game in the paths settings.
Added "open origin in explorer" option to the plugin list context menu.
Added "open INIs folder" option in navigation menu

Improved the tools menu by allowing plugins to define submenus.

v2.1.2

Virtual File System (usvfs) changes:

All the files that are edited inside the virtual folder will get properly edited now, without getting copied over to overwrite. This means that plugins or masters edited in xEdit for example will no longer show up in the overwrite folder as they did before and the changes will instead be applied to the original file instead, like it was supposed to do. The old behaviour can be considered a bug. This will greatly lower the cluttering of the overwrite folder. The overwrite folder will now only contain newly generated files that were not already present in the virtual folder.

Fixed unquoted paths handling for problems with tools such as LODGen.

Added support for texture (.dds) file preview in data tab.

Complete overhaul of export to CSV feature with custom column selection and added entries.
Added mod priority, enabled status, primary category, install date and nexus url columns to Export to CSV feature.
Fixed incorrect plugin order handling for older games.

Added support for all the new Archive types to the extractor plugin.
Fixed missing entry point error messages when opening the mod information dialog for people that have qt dlls referenced in their PATH.
