• Breaking: [Only if you use Crosstab reports] renamed the typo "crosstab_compute_reminder" to "crosstab_compute_remainder" .
• Breaking : [Only if you set the templates statics by hand] renamed files ra.hightchart.js and ra.chartjs.js to erp_framework.highchart.js and erp_framework.chartjs.js respectively.
• Fix an issue with Crosstab when crosstab_compute_remainder = False .
