# V3.18
Among the changes in V3.18 was components V2, while splendid, it did bring with it a few changes you should be aware of.
- IMessage
Messages components type has changed. As a patch you can convert it to an `IEnumerable<ActionRowComponent>` again like so:
```cs
IMessage message = component.Message;
IReadOnlyCollection<IMessageComponent>? components = message.Components;
IEnumerable<ActionRowComponent>? componentsLegacy = components.OfType<ActionRowComponent>();
```
- Nested components
The usage of components with `ActionRowBuilder` and `ComponentBuilder` has a type change as well. You can find examples in [Components_V2_Advanced].
- Components V2 Flag
To use Components V2 in a message (through `ModifyAsync`/`UpdateAsync`/...), a specific flag has to be set. This cannot be undone though :^). You only have to set it if you modify a message that didn't have components v2 in them to begin with (or if you already set the flag manually - obviously). This means that if you created a message with your bot that has components in it, the flag will automatically be set.
Otherwise, you can manually set it like so:
```cs
MessageFlags? flags = component.Message.Flags ?? MessageFlags.None;
flags = flags | MessageFlags.ComponentsV2;
await component.UpdateAsync(m =>
{
m.Flags = flags;
m.Components = cv2builder.Build();
});
```
