 - Brought the docs on `alpha_sd` up to date with the code change from prior PR #853. By @zsusswein in #862 and reviewed by @jamesmbaazam.
 - The `...` argument in `estimate_secondary()` has been removed because it was not used. By @jamesmbaazam in #894 and reviewed by @.
 - All examples now use the natural parameters of distributions rather than the mean and standard deviation when specifying uncertain distributions. This is to eliminate warnings and encourage best practice. By @jamesmbaazam in #893 and reviewed by @sbfnk.
+- The ways that `dist_spec()` with certain/uncertain parameters can be constrained has been clarified. By @sbfnk in #940 and reviewed by @jamesmbaazam.
