    "message": "Fix burnin = 0, reject missing responses, update dependencies (#2)\n\n- `slcm()` stored nothing when `burnin = 0`: `t > burnin - 1` wrapped around on the unsigned counter, so the chains and the `delta` and `q` estimates were all zeros. The check is now `t >= burnin`, which is unchanged for `burnin >= 1`.\n- `slcm()` now stops with an error when `y` contains missing values. A single `NA` used to produce an invalid fit without warning.\n- Every dependency now requires its latest CRAN release, including Rcpp (>= 1.1.2) and RcppArmadillo (>= 15.6.2-1).\n- Version 0.1.1.9000, with a new NEWS.md.",
