Hey @diyahir nice to see you actively using the forum! To use the latest toolchain please follow the[installation guide here](https://docs.fuel.network/guides/installation/). If you are trying to use a prerelease component and don’t want to wait for Fuelup follow the custom instructions below.

**Beta 4**

1. Install toolchain

```auto
fuelup toolchain install beta-4

```

1. Point at beta-4 toolchain

```auto
fuelup default beta-4

```

**Latest**

1. Install toolchain

```auto
fuelup self update

```

1. Point at latest toolchain

```auto
fuelup default latest

```

**Custom**

1. Create your custom toolchain

```auto
fuelup toolchain new testing_channel

```

1. Add the components you want. For example

```auto
fuelup component add fuel-core@0.20.6
fuelup component add forc@0.46.1

```

1. Point at your custom toolchain

```auto
fuelup default testing_channel

```

After pointing it to the latest toolchain you should be able to see all your channels using

```auto
fuelup show

```

```auto
Default host: aarch64-apple-darwin
fuelup home: /Users/calldelegation/.fuelup

Thanks for the response!

My question is more related about the toml configuration which defines the workspace etc.

So for projects that are defining the toolchain used inside the project we must specify the channel, so I want to find where to get the latest beta-4 channel

When i set it to my channel:  
`channel = "beta-4-aarch64-apple-darwin"`

> ¨warning: invalid ‘fuel-toolchain.toml’ in project root: Invalid channel ‘beta’

If I set it to ‘latest’, I get the error:

> warning: invalid ‘fuel-toolchain.toml’ in project root: invalid value: string “latest”, expected one of \<latest-YYYY-MM-DD|nightly-YYYY-MM-DD|beta-1|beta-2|beta-3\> for key `toolchain.channel`

There’s basically a weird error I’m seeing and it’s related to the channel being set to an outdated version, in theory I could remove the toml config and let the system use the default one, but it’s better to define it in the project for proper versioning.

I am noticing that beta-4 is not an option in one of error responses, so it could be that I’m running into some pending issue

The channel name should just be `beta-4`.

This is compiling for me:

```auto
[toolchain]
channel = "beta-4"

[components]
forc = "0.46.1"
fuel-core = "0.20.6"

```

Going to tag @kaya for more detailed response.

This is what I see when I do fuelup show using ‘beta-4’:

beta-4-aarch64-apple-darwin (override), path: …/GitHub/fuel/asset-error-demo/fuel-toolchain.toml  
forc : 0.45.0  
- forc-client  
- forc-deploy : 0.45.0  
- forc-run : 0.45.0  
- forc-doc : 0.45.0  
- forc-explore : 0.28.1  
- forc-fmt : 0.45.0  
- forc-index : 0.21.0  
- forc-lsp : 0.45.0  
- forc-tx : 0.45.0  
- forc-wallet : 0.3.0  
fuel-core : 0.20.4  
fuel-core-keygen : Error getting version string  
fuel-indexer : 0.21.0

so the forc is out of date not to 0.46 and I think causing me a weird issue with Asset that has been fixed after 0.45

Beta-4 toolchain specifically uses forc v0.45.0. We are planning to update to 0.46.1 probably in couple of days. You can follow the PR from [here](https://github.com/FuelLabs/fuelup/pull/496).

Best,

I guess the confusion comes from being able to specify components that don’t override the toolchain, or should it be that the toolchain is not defined but the components are?
