Package: rust-idna Severity: important It seems like it would be a good idea to upgrade the idna crate to version 1, version 0.5 has a "security" issue and the new version of rust-url, which has been requested by jonas needs version 1.
rust-idna 1 supports multiple backends with the backend being chosen by the version of the idna-adapter crate. There are three options. 1.0 - no unicode backend, afaict this would be a downgrade compared to the current situation) 1.1 - unicode-rs backend, this would be essentially what we have now. 1.2 - icu backend, this is the upstream default Whichever backend we select we will have at least two NEW crates. idna_adapter and utf8_iter If we choose the unicode-rs backend we will additionally need the NEW idna_mapping crate. If we choose the icu backend we will additionally need a bunch of NEW icu crates.
