5 This is the release notes for XWiki Platform, XWiki Enterprise and XWiki Enterprise Manager. They share the same release notes as they are released together and have the same version.
6
7 This is the first and hopefully final release candidate of the 4.2 release cycle ([[Roadmap>>Main.Roadmap]]). Being a release candidate, this release contains bugfixes and polishing, most of them focused on the new distribution wizard.
8
9 {{warning}}
10 If you're upgrading from an older version and you use the new Distribution Wizard to upgrade your wiki pages you'll notice that it'll ask you to merge all pages that have been modified between your version and XWiki 4.2. This is because currently the Distribution Wizard doesn't know which version you have and thus asks you to perform the merge manually. This operation may take a long time (up to 20 minutes or so). Thus at the moment if you're upgrading from a previous version we recommend that you Cancel the Distribution Wizard and instead [[Import the new XAR>>platform:AdminGuide.Upgrade]]. This problem is [[reported in this issue>>https://jira.xwiki.org/browse/XWIKI-8252]] and should be fixed in the next release.

13 = New and Noteworthy (since XWiki 4.2 Milestone 3) =
14
15 == Improved Distribution Wizard ==
16
17 The look&feel of the Distribution Wizard has been greatly improved. We added an overview step to explain the goal of the wizard and list its steps.

19 {{image reference="DistributionWizard-WelcomeStep.png"/}}
20
21 The wizard is not yet production ready. It has a couple of issues we hope to fix very soon:
22
23 * information about core extensions is collected lazily and thus if you check distribution details just after starting XWiki you get incomplete information
24 * installing or checking the details of the user interface extension takes a couple of minutes depending on your internet bandwidth and the load of the remote extension repository
25 * some merge conflicts are reported even when the database is empty
26
27 {{image reference="DistributionWizard-UIStep.png"/}}
28
29 Invalid extensions are now marked differently in the last step.

32
33 == Miscellaneous ==
34
35 * The Repository Application now registers an entry in the Application Panel:(((

77
78 {{warning}}
79 Always make sure you compare your ##xwiki.cfg## and ##xwiki.properties## files with the newest version since some configuration parameters were 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.

81
82 == API Breakages ==
83
84 The following APIs were modified since XWiki 4.1.4:
