- scripts/in-namespace.sh set CARGO_TARGET_DIR to the empty string when it was unset, which cargo refuses, and dropped RUSTFLAGS, so the run in the namespace rebuilt what kernel-tests.sh had just built. Each is passed on only where set. - The README's list of unsupported features still had route reflection and graceful restart, both of which exist; the command-line reference lacked SIGUSR1 and exit status 75; the HTTP API reference did not say what errors look like. - The event stream said "missed 0 events" for the best-routes stream, which does not count what it missed; it leaves the count out now. - CI lints bgp-bench with its count-memory feature, which nothing built. - bgp-bench had two unused dev-dependencies; bgp-integration-tests had three dependencies that only its tests and examples use. - install.sh updates apt before installing; two-routers.sh loses an unused variable; small things in the web crate.
