Guillaume Delhumeau 12.1 7 To start this new year, we have updated a lot of our dependencies, to give some freshness to the whole platform. For administrators, it is now possible to define name strategies for new pages. For developers, the new big change is the upgrade of Velocity to the new 2.2 version, which support new syntax expressions. In addition, more than 40 bugs has been fixed since the release of XWiki 11.10.

74 == General Notes ==
75
76 * When upgrading make sure you compare and merge the following XWiki configuration files since some parameters may have been modified, removed or added:
77 ** ##xwiki.cfg##
78 ** ##xwiki.properties##
79 ** ##web.xml##
80 ** ##hibernate.cfg.xml##
81 * Add ##xwiki.store.migration=1## in ##xwiki.cfg## so that XWiki will attempt to automatically migrate your current database to any new schema. Make sure you backup your Database before doing anything.

Thomas Mortagne 4.1 83 == Issues specific to XWiki 12.0RC1 ==
Vincent Massol 1.1 84
Thomas Mortagne 4.1 85 === Velocity 2.2 upgrade ===
Vincent Massol 1.1 86
Thomas Mortagne 5.1 87 While Velocity upgrade bring a lot of nice new improvements it also comes with unavoidable behavior changes that might be a breackage for your scripts or break some extensions:
Thomas Mortagne 4.1 88
Vincent Massol 17.3 89 * The [[Velocity Java API changed quite a lot>>https://velocity.apache.org/engine/2.2/upgrading.html]], if you use advanced features directly in Java there is a big chance that you need to update your code.
Thomas Mortagne 4.1 90 * Most names of Velocity configuration properties have changed ; old names are still functional but will emit a deprecation warning in the log. See the [[Configuration Changes in Velocity 2.1>>https://velocity.apache.org/engine/2.2/configuration-property-changes-in-2.1.html]] page.
91 * We tried to reduce as much as possible the breaking changes in the language using some retro compatibility flags provided by Velocity and some hacks on XWiki side but there is still things for which you might want to be carefull:
92 ** Deprecations: A lot of APIs are now deprecated, they should work fine but will produce a warning in the log (unless you disabled that using the new property ##logging.deprecated.enabled## in ##xwiki.properties##)
Vincent Massol 17.4 93 *** ##$listtool## was already deprecatedd since Velocity 1.6 which added support for allows all List methods to be called on arrays
94 *** ##$sorttool## replaced by ##$collectiontool##
95 *** ##$velocityCount## and ##$velocityHasNext## where already deprecated in Velocity 1.7 without producing any deprecation warning, they now do
Thomas Mortagne 4.1 96 ** Breackages:
Vincent Massol 17.4 97 *** No more Velocity macro semi-local context: in Velocity 1.7 variable set inside a macro were set both in the global context and in a special macro local context. In Velocity 2.x this local context does not exist anymore. In pratice in means that if, in your macro, you ###set## a variable and execute another Velocity template which set the same variable your macro will be affected while it used to be "protected" by the previous explicit ###set##. It's now (since Velocity 1.7 actually) recommended to use the $macro map to manipulate local variable (as in {{code}}#set($macro.myLocalVar = "value"){{/code}}).
Thomas Mortagne 4.1 98 ** Known bugs:
Vincent Massol 17.2 99 *** [[Macro parameter names problem with expression passed to the macro>>https://issues.apache.org/jira/browse/VELOCITY-904?focusedCommentId=17019513&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17019513]]. Should be fixed in 12.0 final.
Thomas Mortagne 4.1 100
Thomas Mortagne 16.1 101 === Servlet 3.1 upgrade ===
102
103 XWiki now requires an application supporting Servlet 3.1 at least. This means for example that XWiki won't work in Tomcat 7 anymore.
