Backward Compatibility and Migration Notes
A new property has been added in xwiki.properties to enable the Javascript Strict mode, which is disabled by default:
# Skin Extensions
#-------------------------------------------------------------------------------------
#-# [Since 12.7.1, 12.8RC1]
#-# Indicate whether the JavaScript skin extensions should be parsed and minified using strict mode. When strict mode is
#-# enabled:
#-# * the JavaScript minification may fail if the code is poorly written. See
#-# https://github.com/google/closure-compiler/wiki/Warnings for a list of errors that may occur. When this happens
#-# XWiki uses the original (unminified) JavaScript source as a fall-back and logs some error messages that indicate
#-# how the bad code can be fixed.
#-# * the minified JavaScript includes the "use strict;" statement which means the code may fail at runtime if it doesn't
#-# follow the ECMAScript strict rules. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode
#-#
#-# The default value is:
# skinx.jsStrictModeEnabled = false
General Notes
- When upgrading make sure you compare and merge the following XWiki configuration files since some parameters may have been modified, removed or added:
- xwiki.cfg
- xwiki.properties
- web.xml
- hibernate.cfg.xml
- 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.
