Piwik 1.7 是一個 Piwik 非常重要的一個里程碑版本，帶來很多新的改進、安全修復和性能方面的大幅提升。

主要特性描述：

• 全新的 Web 分析報告
  • New Loyalty report "Number of visitors who visited the website 1 time, 2 times, etc."
  • New Recency report "Last visit was 0 day ago, 1 day ago, 2 days ago, etc."
  • For each Goal and for your Ecommerce analytics, two new reports: "Visits until conversion", "Days until conversion"
• 可調度的報表 (PDF/HTML) 和圖片圖形提升
  • "All Websites" summary can now be included in the scheduled reports.
    You can now in 3 clicks receive a daily/weekly summary of ALL your websites analytics in your email box. Enjoy!
  • Email Reports now include Graphs by default for key metrics.
    For example you will automatically see a graph for all reports that plot metrics such as the "Visits overview" report or "Goal overview" report.
  • Possibility to include a graph before each table report in PDF/HTML reports (disabled by default)
  • New horizontal bar graphs that look very pretty and allow for better data visualization. These graphs are the default graphs used in Scheduled reports.
  • Graphs now support Unicode characters (chinese, arabic, hebrew, etc.) after you upload the unicode font.
• 大幅的提升可用性
  
  • On most graphs, you can now select the metric to plot. For example you can now plot Pageviews, Revenue or Conversion rate over the last 30 days.
  • You can even plot multiple metrics at once, for example you can compare Conversion rate and Revenue for all goals, or for a specific goal.
  • Dashboard: you can now change the Dashboard Layout to choose 2 columns, 4 columns, or 3 columns with the first one taking half of the width, etc.
    There are many layout options available for everyone to have the optimal analytics experience.
  • Dashboard: you can now "reset" the dashboard layout to the default selection of widgets.
  • In Visitors > Overview, Piwik used to report "Actions" which include all of Page views, Downloads and Clicks on external links.
    Starting in Piwik 1.7 you will now see the detail, ie. 3 different stats and sparklines for Page views, Downloads and Outlinks separately.
• 性能提升
  • New archive.php script, replacing the previous archive.sh, much more efficient and optimized
  • "All websites dashboard" used to fail to load when you track dozens or hundreds of websites. Now it should take a few seconds/less than a minute to load.
