Learning: Forest project requires fvm_ipld_amt version 0.7.5 functionality which is available in the Git revision a633547ae414a333b2d076beef87d4d30cdb7fb4 of the ref-fvm repository, but version 0.7.5 is not yet published to crates.io (only 0.7.4 is available). The Git patch must remain until 0.7.5 is published.

Learning: The fvm_ipld_amt crate version 0.7.5 is required for the Forest project, but it's not yet published to crates.io, which is why the Git patch pointing to the ref-fvm repository is still necessary.
