I looked through some of the reverse dependencies. lintian-brush - no changes seem to be needed. rust-alacritty builds and passes smoke test after pointing at patched alacritty-config and alacritty-terminal rust-alacritty-config cargo test --all --all-targets --all-features passes after bumping dependency. rust-alacritty-terminal cargo test --all --all-targets --all-features passes after bumping dependency and pointing at patched alacritty-config rust-bat - main code built fine after bumping dependency, but one example needed a slight tweak. rust-carapace-spec-clap - new upstream version supports serde-yaml 0.9 rust-lsd - one test fails, but I don't think it's related to the serde-json version, also waiting for chrono-humanise right now.,, rust-rust-code-analysis-cli - already broken and not in testing. rust-test-case - jonas package, only seems to be used for tests, further investigation needed. squeekboard - not investigated yet. rust-config-file - not investigated yet. rust-treediff - not investigated yet.
I also looked at the forward dependencies, and discovered that the unsafe-libyaml crate is needed. Blair Noctis had packaged it but it needed sponsorship. It's now in NEW.
