 # fireSense_ignitionPredict (development version)
 
+- The objective of a fitted model is read with `fireSenseUtils::xgbObjective()`, the one copy shared with `fireSense_ignitionFit`, instead of this module's own lookup; same result. Needs fireSenseUtils (>= 0.2.3.9104).
 - Fix: the objective of the fitted models is read with `xgboost::xgb.config()` (falling back to `attr(model, "params")`), not `model$params`, which is `NULL` for xgboost >= 3 boosters, so every prediction run stopped at the ignition step. `xgboost (>= 3.0.0)` is now in `reqdPkgs`.
 - Breaking: the module now only predicts; it draws nothing and no longer makes `ignitionsAndEscapes`. `fireSense_burn` draws the ignitions and escapes from the new `fireSense_IgAndEscapeDistribution` and `fireSense_IgAndEscapeProbRas`, and places them (`placeIgnitions()`, `coarseToFineMap()` and `fineCoarseTable()` moved there). `flammableRTM` is no longer an input.
 - `fireSense_IgAndEscapeProbRas` layer `escapeProb` is the expected escapes per pixel and year for every pixel (it was NA where no ignition was drawn), no longer clamped to [0, 1]; `ignitionProb` is the expected ignitions.
