- sparklines and Stats history feature were added to the PowerQA core
- Activity Count Widget plugin was improved.
Until now, core had only total number of questions, answers, comments and users. In new version, history of last 30 days will be stocked. In addition, history data is cached into option tables as "cache_history". Therefore, we can use data all over the place without degrading performance.
