6 A bug making impossible to install a XAR extension containing an attachment has been found in this version and is fixed in [[4.1.1>>ReleaseNotesXWikiEnterprise411]].
7 A regression when diffing document history was found in 4.1 and 4.1.1 and is fixed in [[4.1.2>>ReleaseNotesXWikiEnterprise412]].
8 We thus recommend to not install this version and use 4.1.2 or later instead.

12 We've found an important issue in this release with our automatic data migration when upgrading from a version earlier than 4.0. Specifically the migration may fail when migrating wikis having stats, see [[XWIKI-7976>>]] and when migrating DBs that was migrated from MySQL MyISAM previously, see [[XWIKI-7985>>]]. In addition we've also realized that the migration process can be slow on large XWiki databases and we have speed up the process. All these issue are fixed in release 4.1.3.

15 This is the second release of the 4.x cycle ([[Roadmap>>Main.Roadmap]]). This release brings Extension Manager improvements such as merging of configuration documents during extension upgrade, a more gentle learning curve by hiding internal documents from non-technical users, and lots of goodies for the developers such as easy sharing of variables between scripts in different languages.
17 = New and Noteworthy (since XWiki Enterprise 4.0 version) =
19 Here are notable new features and improvements. For the full list of issues (including statistics) see the [[JIRA Dashboard>>]].
21 == Improvements to the Extension Manager ==
23 The speed and reliability of the [[Extension Repository>>extensions:Extension.Repository Application]] has been improved considerably. For example the [[ Extension Repository>>extensions:Extension.WebHome]] is now much faster when you access it from XWiki Enterprise and you should now be able to browse and install extensions in no time.
25 Upgrading applications with related configuration documents is now handled using the merge conflict resolution UI. Changes are displayed as if you were comparing versions from a document's history.
27 {{image reference="EM-mergeConflict.png"/}}
29 If extension installation fails, the error message is extracted from the logs and displayed. You can view the full stack trace by clicking on the error message.
31 (in the image below the job of computing the install plan fails)
33 image:EM-extensionLog.png
35 The install and uninstall plans display extensions like in the dependency section. This way you can follow the link of an extension to find out more about what is going to be installed.
37 image:EM-uninstallPlan.png
39 The install and uninstall process is now completely asynchronous. You can see below how the progress is indicated.
41 image:EM-asyncInstall.png
43 See the [[Extension Manager Application documentation>>doc:extensions:Extension.Extension Manager Application]] for more details.
45 == Hide technical documents from non-technical users ==
47 * Users who do not opt to see hidden documents do not see them on panels or in search results.
48 * For advanced users, it is now possible to specify that a document should be hidden when editing the document (only //wiki// or //wysiwyg// edit modes):(((
49 [[image:HideDocument.png||style="border:1px solid silver" width="240px"]]
51 And now there's a new setting in the user profiles, letting users choose whether they want hidden documents to appear in search results and panels:
53 [[image:ShowHiddenDocuments.png||style="border:1px solid silver" width="300px"]]
55 * If the user doesn't set explicitly the Hidden setting value in his profile, he won't see hidden documents by default. Thus seeing hidden documents is an explicit choice.
56 )))
59 == New types of charts ==
61 We've [[added 2 new types of charts>>extensions:Extension.Chart Macro]], **bar3D** and **line3D**, which draw 3D charts.
63 For example the following code:
65 {{code}}
66 {{chart type='bar3D' source='inline' params='range:B2-B9;series:columns'}}
67 |=Date|=Value
68 |2012-02-21|1.97
69 |2012-02-26|2.96
70 |2012-03-04|3.93
71 |2012-03-11|4.84
72 |2012-03-18|5.83
73 |2012-03-25|4.5
74 |2012-04-01|3.85
75 |2012-04-08|4.87
76 {{/chart}}
77 {{/code}}
79 Will be rendered as this:
81 [[image:chart-example.png]]
84 It's now possible to select [[custom colors in Chart graphs>>extensions:Extension.Chart Macro]]. For example:
86 {{code}}
87 {{chart type="pie" source="inline" params="range:B2-D5;series:columns;colors:C3E3F7,1D9FF5,015891,012A45" title="Chart Test" width="320" height="240"}}
88 | |X |Y |Z
89 |Q1|1.2|3.4|1.3
90 |Q2|4.5|3.4|2.3
91 |Q3|1.2|4.5|9.0
92 |Q4|3.4|1.2|1.2
93 {{/chart}}
94 {{/code}}
96 Will generate:
98 {{image reference="extensions:Extension.Chart [email protected]"/}}
101 == New macro for sending messages ==
103 Whereas the Activity Stream allows users to send a message as well as observing messages and activities of other users, this macro allows the explicit message sending functionality to be duplicated in other places without including the activity stream as well.
105 The code:
107 {{code language="none"}}
108 {{messageSender /}}
109 {{/code}}
111 Produces the following:
113 {{image reference="messageSenderMacro.png"/}}
115 == Danish Translation ==
117 [[image:Denmark.png||width=50px]] XWiki Enterprise is now available in the Danish language.
119 == Global and per-user timezone setting ==
121 Wiki administrators can now use a specific timezone regardless of the clock configuration on the wiki server. The following setting can be found under **Administration > Localization**.
122 Users will find the same setting, allowing them to see dates reflecting their current location. The user setting is accessible through **Profile > Preferences > Localization Preferences**.
124 {{image reference="timezone.jpg"/}}
127 = For developers =
129 * New rendering [[Compatibility Test Suite>>rendering:Main.CompatibilityTestSuite]] to make testing easier and simplify implementation of new syntax Parsers and Renderers. You can checkout the [[Compatibility report>>rendering:Main.SyntaxReport]] for all the syntaxes that are supported out of the box by XWiki.
131 * New diff/merge module has been added to make easier to deal with diff and merge both from component and scripts. See [[Diff module >>extensions:Extension.Diff Module]] for details.
133 == Easy variable sharing between scripts ==
134 It's now much easier to share variable between languages.
135 You can now create a variable in a Groovy script and use it in a Velocity script.
137 For example:(((
138 {{code language="none"}}
139 {{python}}
140 a = "This"
141 {{/python}}
143 {{groovy}}
144 b = "changes";
145 {{/groovy}}
147 {{velocity}}
148 $a $b everything.
149 {{/velocity}}
150 {{/code}}
151 )))
153 == Script access to Component Manager ==
154 With the [[new Component Access Script Service>>Documentation.DevGuide.Scripting||anchor="HXWikiComponentAccess"]] privileged scripts can now easily load components from the Component Manager (XWiki's dependency injection system). This is not available in Velocity because of it's limited capability to load classes.
156 For example:(((
157 {{code}}
158 {{groovy}}
159 def myComponent = services.component.getInstance(MyComponentRole.class)
160 {{/groovy}}
161 {{/code}}
162 )))
164 == Velocity interprets Strings in function calls ==
165 With the [[new Velocity uberspector>>doc:extensions:Extension.Velocity Module||anchor="HMethodArgumentsUberspector"]], Velocity will convert method arguments in string form to formal parameter types when the passed arguments don't match the method signature.
167 For example:(((
168 {{code}}
169 $obj.someMethod('VALUE')
170 // will forward to
171 obj.someMethod(SomeEnum.VALUE)
172 // if obj has a method with signature someMethod(SomeEnum) and not someMethod(String)
173 {{/code}}
175 But this is not limited to enums. The conversion is done using the [[Properties Module>>doc:extensions:Extension.Properties Module]] which means you can create and register custom converters for data types specific to your application domain.
176 )))
179 == Taming of Groovy scripts ==
181 Since traditionally, Groovy scripts can enter into unstoppable infinite loops, use reflection to violate security assumptions, access server resources, or even crash the virtual machine, they have been off limits to non-administrators.
183 In a bid to open up new scripting options to less permitted users (especially in wiki farms where getting Programming Rights is a problem since it means having those rights on the whole farm), steps have been taken to make Groovy safer.
185 Groovy scripts are now technically allowed to users having simple Edit rights but the Groovy Sandbox is currently very restrictive (said differently, you cannot do anything useful with it at the moment! :)). Now that we have the mechanism in place our plan is to slowly open up allowed operations.
187 To enable and test this feature read the document for both the [[Commons Groovy Module>>extensions:Extension.GroovyModuleCommons]] and the [[Platform Groovy Module>>extensions:Extension.GroovyModulePlatform]].
189 === Compilation customizers ===
191 Customizers can be registered to alter the Groovy script as it is compiled such as filtering System.exit() calls and adding timeout checks to loops to prevent infinite looping. Learn more:
193 === Stop run-away scripts after a configurable timeout ===
195 You can now configure your wiki to stop Groovy scripts after a configurable amount of run time. For example if you wish to have a timeout of 10 seconds for your XWiki runtime, you'd configure xwiki's with:
197 {{code language="none"}}
198 groovy.compilationCustomizers=timedinterrupt
199 groovy.customizer.timedInterrupt.timeout=10
200 {{/code}}
202 == Shorthand HQL queries in the Query Manager ==
204 When you send a search query to the Query Manager such as {{code language="none"}}where doc.creationDate > '2008-01-01'{{/code}} It is now assumed that you meant:
206 {{code language="none"}}
207 select doc.fullName from XWikiDocument as doc where doc.creationDate > '2008-01-01'
208 {{/code}}
210 == Bug fixes and improvements ==
212 * Filenames of entries in XAR files are now [[always decoded using UTF-8 during import>>]]. The previous behavior was to use the platform encoding. The filenames have always been encoded using UTF-8 in XAR files, but now also the Unicode extra fields are included, so unpacking XAR files with InfoZIP will result in the filenames beeing properly reencoded with the local filesystems character set.
213 * Temporary files are now placed in a special sub-directory of the normal temporary directory, this sub-directory called "xwiki-temp" is deleted after each startup of the xwiki system so it is critical that nothing else it placed in it. This improvement means that temporary files such as cached attachments will be removed even if the JVM crashes.
214 * Fixed wrong calculation of IDs for stats values making it impossible to upgrade a wiki to version 4.0 if statistics collection is enabled.
215 * Faster first startup time by not running a database migration when it is not needed.
216 * Simplify reverse proxy setup by making all HTTP redirects use relitive URLs.
217 * Add support for bold, italic and monospace in the TeX Renderer
218 * Was impossible to delete then recreate a subwiki with the same name, fixed.
219 * Fixed Javascript error when scrolling over Search Suggest results in Internet Explorer 6.
220 * Trying to change a document's parent from the REST service resulted in an error, fixed.
221 * It is now possible for non-administrators to execute cross-wiki XWQL queries.
222 * Move ComponentManager deprecated methods to Legacy modules
223 * New Groovy module in xwiki-commons
224 * Add legacy module structure for XWiki Rendering
225 * Have one Maven module per XWiki Rendering syntax
226 * Separate Event Syntax from Rendering API by moving it to a Syntax module
227 * Plain syntax and Event syntax have been moved out of Rendering API nto their own modules.
228 * [[XWIKI-7913>>]] Could not register a Javascript or CSS skin extension for the whole wiki.
231 See the full list of [[JIRA issues>>]] fixed in the 4.1 release cycle.

282 = Test Report =
284 You can check the [[manual test report>>TestReports.ManualTestReportXE41]] to learn about what was tested and the results on various browsers.
286 = Backward Compatibility and Migration Notes =
288 == General Notes ==
290 {{info}}
291 If you're running in a multiwiki setup you'll also need to define the property // in your //xwiki.cfg// file if you want to explicitly name some databases to be migrated as the default is now to migrate all databases. Database that are not migrated could not be accessed.
292 {{/info}}
294 You may also want to [[import the default wiki XAR>>Main.Download]] in order to benefit from all the improvements listed above.
296 {{warning}}
297 Always make sure you compare your ##xwiki.cfg## and files with the newest version since some configuration parameters were 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.
298 {{/warning}}
300 == Issues specific to XWiki Enterprise 4.1 ==
302 The old experimental real-time synchronization plugin for the WYSIWYG content editor has been retired. We hope that its functionality will be replaced by the real-time editing feature developed on the [[Wiki 3.0>>]] project. If you want to continue using the old plugin you need to:
304 * take the code from [[##xwiki-contrib/retired## GitHub repo>>]]
305 * add the client and server side as dependencies to the WYSIWYG client and server side respectively
306 * modify ##WysiwygEditorFactory## to register the factory of the sync plugin
307 * rebuild the editor and update the jars and client side resources on your XWiki Enterprise instance
309 == API Breakages ==
311 The following APIs were modified since version 4.0:
313 * Breakage in Query module done to support adding several Filters to a Query:(((
314 {{code language="none"}}
315 org.xwiki.query.QueryFilter: Method 'public java.util.List filterResults(java.util.List)' has been added to an interface
316 {{/code}}
317 )))
318 * This method should have been internal from the beginning:(((
319 {{code language="none"}}
320 org.xwiki.environment.EnvironmentConfiguration: Class org.xwiki.environment.EnvironmentConfiguration removed
321 {{/code}}
322 )))
323 * The Job module is new and is still considered a "young API":(((
324 {{code language="none"}}
325 org.xwiki.job.AbstractJob: Changed type of field status from org.xwiki.job.internal.DefaultJobStatus to org.xwiki.job.internal.AbstractJobStatus

340 * The Extension module is relatively new and is still undergoing some API tuning:(((
341 {{code language="none"}}
342 org.xwiki.extension.job.plan.ExtensionPlan: Return type of method 'public java.util.Collection getTree()' has been changed to org.xwiki.extension.job.plan.ExtensionPlanTree

344 {{/code}}
345 )))
346 * This class was added in 3.2M2 by error in a user-public package. It's been moved again in the internal package as it should have been. We don't expect many users to be affected by this:(((
347 {{code language="none"}}
348 com.xpn.xwiki.doc.merge.MergeUtils: Class com.xpn.xwiki.doc.merge.MergeUtils removed
349 {{/code}}
350 )))
351 * In 2.2M1 we refactored BaseCollection to add getXClass() but we forgot to add it to the ObjectInterface interface. Even though this could break user we think it's very limited since nobody should implement directly ObjectInterface; instead everyone should extend BaseClass or BaseCollection:(((
352 {{code language="none"}}
353 com.xpn.xwiki.objects.ObjectInterface: Method 'public com.xpn.xwiki.objects.classes.BaseClass getXClass(com.xpn.xwiki.XWikiContext)' has been added to an interface

355 )))
356 * The Autotag plugin has been extracted from the oldcore module and is now a module on its own so the following are not real breakages:(((
