5 This is the release notes for [[XWiki Commons>>]], [[XWiki Rendering>>]], [[XWiki Platform>>]] and [[XWiki Enterprise>>]]. They share the same release notes as they are released together and have the same version.
7 6.4 branch is mainly dedicated to improvement and bugfixes on things introduced during 6.x and in general. This version also introduce some developer oriented improvements: allow wiki based skins to overwrite macro.vm template, allow filesystem skins indicating explicitly the skin they are inheriting from, allow any component to be injected with its ComponentDescriptor, Panels and UI extensions are now executed with the right of their author so among other things they can use APIs requiring Programming rights.
9 = New and Noteworthy (since XWiki 6.3) =
11 [[Full list of issues fixed and Dashboard for 6.4>>]].
13 == New Parameters for Document Tree Macro ==
15 We added 3 new parameters to the [[Document Tree Macro>>extensions:Extension.Document Tree Macro]]:
17 * **filterByClass**: show only the documents that have an object of the specified type. The value of this parameter is the full name of an XWiki document that holds a class definition. For example, 'Blog.CategoryClass' can be used to show only the documents that represent blog categories.
18 * **openTo**: the id of the node to open the tree to. All the ancestors of the specified node, up to the root of the tree, will be opened also.
19 * **showOnlyViewable**: show only the wiki, space and document nodes for which the current user has view right. If this is set to false then the wiki, space and document nodes that are not viewable by the current user are listed in the tree using their names. The user won't be able to see their content by following their links though (the user will just be aware of their existence).
21 == Miscellaneous ==
23 * It's [[now possible to send Registration emails in HTML>>extensions:Extension.Administration Application||anchor="HRegistration"]] (by default they're sent in plain text). This is achieved by fully supporting any MIME content in the "Validation Email Content" and "Confirmation Email Content" sections of the Registration Administration UI. For example for the "Validation Email Content" field, you could use the following template to send HTML emails:(((
24 {{code language="none"}}
25 #set ($wikiname = $request.serverName)
26 #set ($host = ${request.getRequestURL()})
27 #set ($host = ${host.substring(0, ${host.indexOf('/', ${mathtool.add(${host.indexOf('//')}, 2)})})})
28 Subject: Validate your account on ${wikiname}
29 Content-type: text/html; charset=iso-8859-1
31 <p>Hello <b>${xwiki.getUserName("XWiki.$xwikiname", false)}</b>,</p>
32 <p>This email address was used to register a new account on ${wikiname}. If you did not make the request, please ignore this message.</p>
33 <p>In order to activate your account, please follow this link:
34 ${host}${xwiki.getURL('XWiki.AccountValidation', 'view', "validkey=${validkey}&xwikiname=${xwikiname}")}</p>
35 {{/code}}
36 )))
38 See the [[full list of JIRA issues>>]] fixed in this release.
40 = For Developers =
42 == Velocity changes ==
44 === Remove a Velocity Engine from the cache ===
46 ##org.xwiki.velocity.VelocityFactory## now provide an API to remove a cached Velocity Engine.
48 === Overriding Velocimacros in wiki-based skins ===
50 It's now possible to override the ##macros.vm## template in a wiki based skin (object property and attachment). Any modification to this template is also taken into account (the Velocity engine is recreated when the template is modified).
52 === Cleanup unprotected namespaces ===
54 VelocityEngine automatically get rid of the passed namespace at the end of execution unless it's protected.
56 In practice in means that the following:
58 {{code language="java"}}
59 engine.evaluate(new VelocityContext(), new StringWriter(), "namespace", "#macro(mymacro)toto#end")
61 Writer out = new StringWriter();
62 engine.evaluate(new VelocityContext(), out, "namespace", "#mymacro()")
64 System.out.println(out.toString())
65 {{/code}}
67 will now print
69 {{code language="none"}}
70 #mymacro()
71 {{/code}}
73 To get
75 {{code language="none"}}
76 toto
77 {{/code}}
79 you need the following
81 {{code language="java"}}
82 engine.startedUsingMacroNamespace("namespace")
84 try {
85 engine.evaluate(new VelocityContext(), new StringWriter(), "namespace", "#macro(mymacro)toto#end")
87 Writer out = new StringWriter();
88 engine.evaluate(new VelocityContext(), out, "namespace", "#mymacro()")
90 System.out.println(out.toString())
91 } finally {
92 engine.stoppedUsingMacroNamespace("namespace")
93 }
94 {{/code}}
96 == Skins system improvements ==
98 Support for a new configuration file has been introduced in filesystem skins.
100 Right now it supports a ##parent## property to indicate another skin to inherit from. If set to an empty value ({{code language="properties"}}parent={{/code}}) the skin will directly inherit from the WAR; if not set at all it will behave as before which means inherit from whatever is configured in ##xwiki.cfg##'s ##xwiki.defaultbaseskin## property.
102 == Component Metadata Access ==
104 If your Component implementation needs to get access to its component metadata (i.e. its ##ComponentDescriptor##) then it can [[get it injected automatically>>extensions:Extension.Component Module||anchor="HComponentMetadata"]]. For example:
106 {{code language="java"}}
107 import org.xwiki.component.descriptor.ComponentDescriptor;
108 ...
109 @Component
110 @Singleton
111 public class MyComponentImpl implements MyComponent
112 {
113 @Inject
114 private ComponentDescriptor<MyComponent> descriptor;
116 public void doSomething()
117 {
118 String hint = this.descriptor.getRoleHint();
119 ...
120 }
121 }
122 {{/code}}
124 == Panels executed with the rights of their author ==
126 It's now possible to write script requiring programming right in panels as long as you have programming right, same as wiki macros.
128 == UI extensions executed with the rights of their author ==
130 What you can execute in UI extension used to depend on current document author right, it's now based on the own ui extension author.
132 == Miscellaneous ==
134 * Added new APIs to get all the icon themes present on the wiki, and all icons that these icon themes contain.(((
135 {{code language="velocity"}}
136 $services.icon.getIconSetNames()
137 $services.icon.getIconNames()
138 $services.icon.getIconNames("Font Awesome")
139 {{/code}}
140 )))
141 * A new parameter has been added to the ##get## action and the ##plain## xpage: ##htmlHeaderAndFooter##, which add the HTML headers (##<html>##,##<head>##,##<body>##, etc...) and footers (##</body>##, ##</html>##, etc...). It could be useful to create light popups that display only the document content without any UI.
142 * XWikiAttachment now provide ##setAuthorReference## and ##getAuthorReference## APIs
143 * ##org.xwiki.logging.event.LogEvent## now have a getTimestamp() method returning the number of milliseconds elapsed from 1/1/1970 until logging event was created.
144 * A SOLR-based implementation of the standard REST search resource has been added
145 * The [[Solr Query>>extensions:Extension.Solr Search Query API]] parameter ##xwiki.supportedLocales## has a new default value: the list of supported locales configured for the current wiki (where you execute the search).
146 * The ##{{{@Component}}}## annotation is no longer inheritable. Thus each component implementation class must now define it and not rely on it being present in some Abstract class.
147 * The XWiki build now verifies that all components are correctly listed in ##META-INF/components.txt## files and that the threading model is explicitly defined (i.e. that either ##{{{@Singleton}}}## or ##{{{@InstantiationStrategy(ComponentInstantiationStrategy.PER_LOOKUP)}}}## is used). If not, the build fails. A new ##{{{@Component}}}## annotation parameter has been added for explicitly mentioning that a Component should not be statically registered (these components are usually used in tests). It's used as follows:(((
148 {{code language="java"}}
149 @Component(staticRegistration = false)
150 {{/code}}
151 )))
153 == Upgrades ==
155 The following dependencies have been upgraded:

172 = Known issues =
174 * [[Bugs we know about>>]]
176 = Backward Compatibility and Migration Notes =
178 == General Notes ==
180 When upgrading make sure you compare your ##xwiki.cfg##, and ##web.xml## files with the newest version since some configuration parameters may have been modified or added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
182 == Issues specific to XWiki 6.4-milestone-1 ==
184 * VelocityEngine automatically get rid of the passed namespace at the end of execution unless it's protected. See [[Velocity section>>||anchor="HVelocitychanges"]].
185 * If upgrading the content in the DistributionWizard, and the upgrade is from XWiki 6.2.x or 6.3, you might get a conflict for the document Blog.BlogSheet. Unless you have done modifications to that document, please keep the new version; otherwise please keep the merged, or if not available, keep your version. For details see issue [[XWIKI-11450>>]].
187 == API Breakages ==
189 WYSIWYG's MacroService API was not previously considering a multiwiki environment. Added a few new methods:
191 {{code language="none"}}
192 org.xwiki.gwt.wysiwyg.client.plugin.macro.MacroService: Method 'public org.xwiki.gwt.wysiwyg.client.plugin.macro.MacroDescriptor getMacroDescriptor(java.lang.String, java.lang.String, java.lang.String)' has been added to an interface

196 {{/code}}
198 New method require to clean the Velocity engines cache:
200 {{code language="none"}}
201 org.xwiki.velocity.VelocityFactory: Method 'public org.xwiki.velocity.VelocityEngine removeVelocityEngine(java.lang.String)' has been added to an interface
202 {{/code}}
