Apache Wicket 7.1.0 released

25 Oct 2015

The Apache Wicket PMC is proud to announce Apache Wicket 7.1.0!

This release marks another minor release of Wicket 7. We use semantic versioning for the development of Wicket, and as such no API breaks are present breaks are present in this release compared to 7.0.0.

New and noteworthy

Significant improvement in performance while adding components to the component hierarchy. There was a regression in performance introduced by component queuing. The algorithm checked if there were any components to be dequeued, but did so in a O(n^2) way. This was fixed.

Upon further investigation we found that adding components is O(n^2) since 1.3 (when memory was scarce and expensive). We fixed that and made it roughly O(1).

This means that when you have a page with 10k components on it, the adding won’t slow you down any more, and the new way of adding components will scrape a few ms off your overall average response time.

This release also fixes several bugs where head sections were not rendered, i18n JavaScript resources could not be loaded, Range: header parsing and a couple of component queuing issues.

Using this release

</dependency>

Or download and build the distribution yourself, or use our convenience binary package
