5 This is the release notes for [[XWiki Commons>>http://commons.xwiki.org]], [[XWiki Rendering>>http://rendering.xwiki.org]], [[XWiki Platform>>http://platform.xwiki.org]] and [[XWiki Enterprise>>http://enterprise.xwiki.org]]. They share the same release notes as they are released together and have the same version.

7 This milestone release brings an upgrade to Java 8 runtime, improvements to Extension Manager and Flavors, and a new Tips panel that replaces the old Quick Links panel.

9 = New and Noteworthy (since XWiki 8.0) =
10
11 [[Full list of issues fixed and Dashboard for 8.1>>https://jira.xwiki.org/secure/Dashboard.jspa?selectPageId=13603]].
12
13 == Requires Java 8 ==
14
15 Java 8 is now required to run XWiki. If you use an earlier version of Java, you'll get an error while starting XWiki such as:
16
17 {{code language="none"}}
18 java.lang.reflect.InvocationTargetException
19 [...]
20 Caused by: java.lang.UnsupportedClassVersionError: org/xwiki/tools/jetty/listener/NotifyListener : Unsupported major.minor version 52.0
21 [...]
22 {{/code}}
23
24 == Active Installs ==
25
26 New widget displayed on the dashboard to see the number of Active Installs count per XWiki Cycle version:
27
28 {{image reference="versionspercycle.png"/}}
29
30 == Tips Panel ==
31
32 A new [[Tips Panel>>extensions:Extension.Help Application||anchor="HTipsPanel"]] has been added by default. Example:
33
34 {{image reference="tippanel-1.png"/}}
35
36 {{image reference="tippanel-2.png"/}}
37
38 == Sandbox Relocation ==
39
40 The Sandbox pages were previously accessible through a link in the Quick Links Panel. This link has been removed and instead a Sandbox entry has been added in the [[Applications Panel>>extensions:Extension.Panels Application||anchor="HApplicationPanel"]].
41
42 {{image reference="sandbox-appbar.png"/}}
43
44 In addition the message about the shortcut key to use the "Jump To Page" feature has been moved to the new Tips Panel.
45
46 Here's how the home page looks like now:
47
48 {{image reference="home.png" width="960px"/}}
49
50 == Extension Manager improvements ==
51
52 === Repair invalid extensions ===
53
54 The Extension Manager now tries to repair automatically any invalid dependency and also provides a "Repair" button to repair specific invalid extensions.
55
56 {{image reference="repair.png"/}}
57
58 {{image reference="repairplan.png"/}}
59
60 === Apply namespaces constraints in the UI ===
61
62 The namespaces constraints introduced in 8.0 are now taken into account in the UI which won't propose an option that will fail in the install plan.
63
64 === Move to farm ===
65
66 It's now possible to install on farm an extension installed in a subwiki directly from the UI.
67
68 {{image reference="installonfarm.png"/}}
69
70 === Dependency on root ===
71
72 When using Extension Manager from main wiki it's now allowed to install/upgrade an extension which require upgrading/install farm level dependency. It also automatically propose to install on farm a new dependency which indicate it as constraint. This will make easier to deal with extension have an API that have to be installed on root and a XAR extension UI that should usualy be install on a wiki.
73
74 It's still forbidden from subwiki in the standard UI (any script with programming right can enable it in the install request). That might change in the future but need to be discussed more.
75
76 === Managed dependencies ===
77
78 Extension Manager now support the concept of managed dependencies. It's pretty much the same thing that the {{code language="xml"}}<dependencyManagement>{{/code}} in Maven.
79
80 It still need to be supported in the Repository Application. See [[https://jira.xwiki.org/browse/XWIKI-13281]].
81
82 == Flavors improvements ==
83
84 * Known flavors are not validated anymore before ending up in the flavor picker of the Distribution Wizard. This speed up a lot the use case where you just want to install default XWiki Flavor or XE UI. See [[extensions:Extension.Flavor Module||anchor="HKnownflavors"]] for more details.
85 * Flavors are now also searched in the local repository. This makes easier to embedded flavors in a distribution for setups with no network access.
86
87 == Miscellaneous ==
88
89 * The ##xwiki.usedefaultweb## parameter from ##xwiki.cfg## has been removed. See below.
90 * The Annotations Application's Administration section has been updated to present the exception spaces as "locations", using the ##documentTree## macro. The behavior has not been changed.(((
91 {{image reference="annotationsAdminSection.png" width="960px"/}}
92 )))
93 * Job module does not validate stored status at startup. This might improve a lot the startup time when there is a lot of status. Also there seems to still be use cases where XStream get lost in edge case when parsing, this was blocking the whole XWiki startup for a very long time.
94
95 See the [[full list of JIRA issues>>https://jira.xwiki.org/sr/jira.issueviews:searchrequest-printable/temp/SearchRequest.html?jqlQuery=project+in+%28XCOMMONS%2C+XRENDERING%2C+XWIKI%2C+XE%29+and+status+%3D+Closed+and+resolution+%3D+Fixed+and+fixVersion+%3D+%228.1-milestone-1%22&tempMax=1000]] fixed in this release.
96
97 = For Developers =
98
99 == Deferred JavaScript Module Dependency Loading ==
100
101 You can extend a feature provided by some JavaScript module without knowing where that module is loaded from (by RequireJS) with the following code:
102
103 {{code language="js"}}
104 require(['deferred!module'], function(modulePromise) {
105 modulePromise.done(function(module) {
106 // Do something with the module, if the module is loaded by someone else.
107 });
108 });
109 {{/code}}
110
111 This basically says to RequireJS: "let me know when this module is loaded by someone else" (someone else being an other script on the same page). You can read more about this on the [[Developer's Guide>>platform:DevGuide.JavaScriptAPI||anchor="HDeferredDependencyLoading"]].
112
113 == Upgrades ==
114
115 The following dependencies have been upgraded:
116
117 * [[JSqlParser 0.9.5>>https://jira.xwiki.org/browse/XWIKI-13215]]
118 * [[slf4j 1.7.20>>https://jira.xwiki.org/browse/XCOMMONS-938]]

125 * [[logback 1.1.7>>https://jira.xwiki.org/browse/XCOMMONS-953]]
126
127 == Miscellaneous ==
128
129 * IRC Bot Application has been moved to XWiki Contrib under the new extension id of ##org.xwiki.contrib:application-ircbot-ui##
130 * Selenium Application had been moved to XWiki Contrib under the new extension id of ##org.xwiki.contrib:application-selenium##
131 * FAQ Application has been moved to XWiki Contrib under the new extension id of ##org.xwiki.contrib:application-faq-ui##
132 * The XAR plugin now also verifies that Translation pages are using the ##plain/1.0## syntax (it checks pages having a Translation xobject in them).
133 * This Methods Arguments Velocity Uberspector [[now supports calling varargs methods>>extensions:Extension.Velocity Module||anchor="HMethodArgumentsUberspector"]].
134 * Starting With XWiki 8.1M1, the backward-compatibility tool we use is [[Revapi>>http://revapi.org/]]. We had to move away from CLIRR since it didn't support Java 8 constructs.
135

158
159 * [[Bugs we know about>>https://jira.xwiki.org/secure/IssueNavigator.jspa?reset=true&jqlQuery=category+%3D+%22Top+Level+Projects%22+AND+issuetype+%3D+Bug+AND+resolution+%3D+Unresolved+ORDER+BY+updated+DESC]]
160
161 = Backward Compatibility and Migration Notes =
162
163 == General Notes ==
164
165 When upgrading make sure you compare your ##xwiki.cfg##, ##xwiki.properties## and ##web.xml## files with the newest version since some configuration parameters may have been modified or added. Note that you should add ##xwiki.store.migration=1## so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
166
167 == Issues specific to XWiki 8.1-milestone-1 ==
168
169 * The ##xwiki.usedefaultweb## parameter has been removed from ##xwii.cfg##. This parameter had not been working since XWiki 7.2-milestone-1; when we introduced Nested Pages we had to make a choice and we decided to support addressing top-level Nested Pages without having to have ##WebHome## in the URL (nor having to finish URLs with a trailing ##/##). For example, ##http:~/~/<server>/xwiki/bin/view/something## points to ##something.WebHome## by default since XWiki 7.2-milestone-1.
170 * Since we've modified content of the Quick Links Panel, the Distribution Wizard may detect a merge conflict if this panel was customized. In addition, the Quick Links panel may disappear after an upgrade to 8.1M1+. You can add it back from the administration UI if you want to keep it (e.g. if it has been customized).
