# Legacy Questions

## X, Y, Z does not work! It doesn't return a valid value anymore.
If you're currently using an older version in stable branch, please
upgrade to the latest pre-release version to ensure maximum
compatibility. Several features may be broken in older
versions and will likely not be fixed in the version branch due to
their breaking nature.

Visit the repo's [release tag] to see the latest public pre-release.

## I came from an earlier version of Discord.NET 1.0, and DependencyMap doesn't seem to exist anymore in the later revision? What happened to it?
The `DependencyMap` has been replaced with Microsoft's
[DependencyInjection] Abstractions. An example usage can be seen
[here](https://github.com/foxbot/DiscordBotBase/blob/csharp/src/DiscordBot/Program.cs#L36).
