 # stressaddition 3.0.0
 
+## Breaking changes
 * Renamed all instances of "effect" to "survival".
 * Renamed all instances of "ec" to "lc".
-* Renamed `predict_mixture()` to `multi_tox()`.
+* Renamed `predict_mixture()`, which was a temporary development name, to `multi_tox()`.
 * The argument `proportion_ca` in the mixture model `multi_tox()` was renamed and its value reversed. It is now called `sa_contribution` and specifies the proportion of stress addition in the calculation of toxicant stress. To convert your code from the old version use this equation: sa_contribution = 1 - proportion_ca.
 * Renamed `stress_tox_sam` to `stress_tox_sa` in the output of `multi_tox()`.
+
+## Bugfixes
 * Fixed a bug where `plot_stress()` with argument `which = NULL` would result in an error. Now it correctly draws the axes without data.
-* Newly exported function `log10_ticks()` for calculating tick mark labels and positions on a base 10 logarithmic axis.
