They also differ in how many they are when we have formation fractions but no pathway to sink. -- The order of some of the information blocks in `print.summary.mkinfit.R()` has been ordered in a more logical way +- The order of some of the information blocks in `print.summary.mkinfit.R()` has been ordered in a more logical way. ## MINOR CHANGES - The vignette FOCUS_Z has been simplified to use formation fractions with turning off the sink, and slightly amended to use the new versions of DT50 values calculated since mkin 0.9-29. -- All vignettes have been rebuilt so they reflect all changes +- All vignettes have been rebuilt so they reflect all changes. - The ChangeLog was renamed to NEWS.md and the entries were converted to markdown syntax compatible with the `tools::news()` function built into R. |
