Page History

...

If you are using Java 6 or newer, than Wicket will be configured to use java.util.Properties#load(Reader(in, "utf-8")) for files with "*.utf8.properties" extension.

XML based property files

The file extension for xml based property files is changed from .xml to .properties.xml.
This way it is possible to use pages with XML markup type and xml based property files. Part of WICKET-2035.

TabbedPanel

ITab.getPanel() now returns WebMarkupContainerWithAssociatedMarkup instead of Panel so it is now possible to create tabs using Fragments or Panels rather then just Panels.
TabbedPanel.setSelectedTab() is now chainable
TabbedPanel now takes a List<? extends ITab> rather then List<ITab>

getResourceSettings().setAddLastModifiedTimeToResourceReferenceUrl() has been replaced

With https://issues.apache.org/jira/browse/WICKET-3028^{Image Removed} and https://issues.apache.org/jira/browse/WICKET-3021^{Image Removed} this method was replaced. The timestamp, which previously was added as a query parameter to the resource url is now part of the file's basename (the name part before the extension). This has several advantages and gives you best possible caching support. See for example chapter

Use fingerprinting to dynamically enable caching

in

http://code.google.com/intl/de-DE/speed/page-speed/docs/caching.html^{Image Removed}

The feature is enabled by default so unless you want to disable it with getResourceSettings().setUseTimestampOnResources(boolean) or query its state with getResourceSettings().getUseTimestampOnResources() you usually don't have to care about it at all. Timestamping only works when the ResourceReference supports a last modified timestamp and returns a non-null timestamp for method ResourceReference.getLastModified(). This is always true for package resources and wicket:link.
