On this page, we attempt to give a chronological account of significant updates to the mcplots site, in particular
- Additions of new Generators and Versions
- Additions of new Rivet analyses
- Updates to Rivet versions
- Significant changes to the amount of statistics, new capabilities, or bug fixes to each of the generators and analyses already on the site.
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 slightly 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.
2015/12/08 - MCPLOTS public release
- Epos 1.99 / CRMC 1.0, 1.2, 1.3, 1.4, 1.5.3 and 1.5.4, Pythia 8.209, 8.210 and 8.212, Sherpa 2.2.0, Vincia 1.2.00, 1.2.01 and 1.2.02

- Updated design of the Generators Versions and 'Custom' Generator Group pages to have better overview of versions and tunes available on the site.
2015/02/23 - MCPLOTS public release
- Pythia 6.428, Pythia 8.180, 8.183 and 8.185, Sherpa 1.4.5, 2.1.0 and 2.1.1

- New analyses:
- Temporary removed bottom quark analyses due to issues with generators steering cards. To be re-added in the next release.
- 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.
- Corrected bugs for Herwig++ W+jets and Phojet ppbar runs. Thanks to Test4Theory volunteers Crystal Pellet and Ray Murray for helping us track this down.
- Updated Test4Theory for compatibility with Scientific Linux 6.
- Updated and reorganized tune groups. New tab dedicated to Soft-Inclusive MCs (generators specializing in diffraction, min-bias, etc).
- Updated plotter. Improved y axis ranges for plots with large uncertainties. Reduced risk of plot points being hidden under legends.
- Included a Facebook "like" button, currently as an experimental social feature, to be kept or removed in the future.
- Removed Pythia 8.157 (deemed obsolete).
- Reduced number of tune variations available for the oldest versions of Pythia 6 and 8.
