2017/12/05 - MCPLOTS public release
- Rivet 2.4.0
- The plotting tool has been updated, to correct labeling on several plots and introduce a revised design template with a slightly wider overall aspect ratio (to fit better on slides), the main and ratio panes now touching each other and thus enlarging the total data display area despite reducing the height, and the black top bar replaced by ordinary black-on-white text. Note also that the ratio pane is now using a logarithmic axis centred on the range [0.5, 2] with a bit of margin on either side.

- Expanded validation framework to include new "Tuning Validation" page, on which the chi2 values of different tunes of each generator are compared to each other. (We still choose not to show any direct comparisons between different generators, as the interpretation of such comparisons is more involved and the simple compound chi2 we calculate here could potentially be misleading.)
- Rivet 1.8.3. Thanks to Test4Theory volunteer Crystal Pellet for alerting us to the new version.
