chore: stamp the 0.6.16 release notes - #488
Merged
Merged
Conversation
0.6.16 has not been published to crates.io yet, so the [Unreleased] section is folded into the existing 0.6.16 entry instead of opening a new version. Covers #475, #478, #481, #482, #485. All release gates verified locally: - cargo test --all-features (614 unit + 73 doctests, 0 failed) - cargo fmt --all -- --check - cargo clippy --all-features (2018+2024 idioms, -Dwarnings) - cargo +1.85.0 build --all-features (MSRV) - cargo package (146 files, 2.1MiB)
The LLVM coverage engine instruments the whole serial test run (--test-threads 1). On a slow shared runner the instrumented run could exceed tarpaulin's default 60 s per-binary timeout; observed as 'Timed out waiting for test response' while test_logit (a 52181x94 logistic-regression fit) was running. Two changes: - test_logit now uses a 10000x94 matrix with the same class ratio (418 of 10000 positive). The test asserts the same property and finishes in ~0.5 s instead of ~3.5 s. - The coverage job builds in release mode (--release) and raises the tarpaulin timeout to 600 s.

Current behaviour
0.6.16is stamped inCargo.tomland has aCHANGELOG.mdsection, but the version was never published to crates.io. Five merged PRs (#475, #478, #481, #482/#483, #485) sit in[Unreleased]or have no entry at all. Separately, the coverage job flaked: the LLVM-instrumented serial run exceeded tarpaulin's default 60 s per-binary timeout whiletest_logit(a 52181x94 logistic-regression fit) was running.New expected behaviour
