snforge new fails, is it expected?

Created package.
    Removing cairo_test from dev-dependencies
error: cannot get dependencies of `[email protected]`

Caused by:
    cannot find package `assert_macros ^2.11.3`
[ERROR] Failed to fetch created project: `scarb` exited with error

For me it works, both on scarb 2.8.5 and 2.10.0. Which version are you using @kkawula ? Are you sure you've pulled last changes?

It is due to setting assert macros to Scarb version instead of Cairo version, the problem occurs only for Scarb 2.11.3. Will be fixed soon.
