This is a feature update. This build is not compatible with Mass Effect Legendary Edition.

New features

A lot of work has been done to support 'Download with Manager', a feature that will be enabled for the masseffect, masseffect2, and masseffect3 domains on NexusMods soon. This will allow you to directly download mods into Mod Manager with one click. As a result of this, Mod Manager is now single-instance - you can only open one copy at a time
- Mod Manager will configure nxm:// links to open Mod Manager on every boot. If you don't want Mod Manager to do this, turn it off in the settings. On first boot this handler will download and configure itself
The application has been upgraded to .NET 5. This should improve performance a bit and increase stability by reducing the amount of files the executable must unpack
The Alternate DLC DLCRequirements descriptor now supports +/-, to disable the option if the criteria is not met. Mods must target cmmver 6.3 or higher to use this feature.

Changed features

Game detection criteria has been tightened. You can now only select game executables that exactly match the latest supported versions. This should have no impact, but will prevent users from trying to mod Legendary Edition games in the event they have the same executable names
NexusMods 'endorse' feature will now throw messages if you haven't downloaded the mod, or it is too soon after download to endorse the mod
Diagnostics now list the antivirus products
Nexus File Search has been significantly improved, with options to filter by category, direct mod download (requires NexusMods premium subscription), and more detail for mods. It also now features autocomplete for searchable items
In the Manage Target panel, there is now a list of installed official DLC
Modified basegame files are no longer shown if the game is texture modded as all files would be modified to remove empty mips and tag the files
Installed mods in Manage Target panel can now show what options were chosen at install time

Mods that incorrectly use ConditionalDLC with COND_MANUAL on AlternateDLC will now have warning logs occur. Mods targeting cmmver 6.3 and higher will not load if this issue is detected. Use DLCRequirements instead.
#222 Fix ME2 mods throwing a warning about JPN localization when deploying. It was using the ME3 list of languages
Fix some memory leaks when importing mods

Fix several issues when directly downloading from NexusMods by clicking Download with Manager on the website
Localize to DEU

Localize to RUS
Add dialog if mod is downloaded from a non-mass effect domain due to how nxm:// handler is designed on NexusMods
Do not download mods from non ME-domains over nxm://

Fix wrong .Contains() method being used, because some libraries like to reinvent the wheel, but make it square. Should fix the domain error that appears when downloading mods directly from NexusMods into M3

Fix online content not validating due to bug in new hash checking code that was implemented in 6.3
