0.38.3

Migrating to Scarb 2.11.0

snforge relies on presence of both snforge_std and snforge_scarb_plugin dependencies. Due to changes in dependencies resolving in Scarb action might be necessary to continue using snforge.

If using Scarb version < 2.11.0 with any version of snforge_std

No action needed

If using Scarb version >= 2.11.0 with snforge_std >= 0.38.3

No action needed

If using Scarb version >= 2.11.0 with snforge_std < 0.38.3

Action required. In your Scarb.toml file, add snforge_scarb_plugin dependency with the version matching that of snforge_std

E.g. change this

snforge_std = "0.34.1"

to this

snforge_std = "0.34.1"
snforge_scarb_plugin = "0.34.1"

Alternatively, we strongly recommend upgrading to at least snforge version 0.38.3. Then, no action is needed as outlined above.
