API CHANGE Changed Translatable schema from auxilliary tables (SiteTree_lang, SiteTree_lang_Live) to automatically filtered records on the original table (SiteTree, SiteTree_Live), using $Lang and $OriginalID properties. Incompatible update to old schema, migration script is in the works.
API CHANGE Removed Translatable::get_one(), Translatable::write()
ENHANCEMENT Simplified Translatable tree generation by using getSiteTreeFor() in CMSMain->createtranslation()
ENHANCEMENT Added AllChildrenIncludingDeleted(), augmentNumChildrenCountQuery(), augmentAllChildrenIncludingDeleted(), augmentStageChildren() to Translatable class to allow for more stable tree generation.
ENHANCEMENT Moved definition of Translatable schema from augmentDatabase() to Translatable->extraStatics()
ENHANCEMENT Changes to the CMS language selection refresh the whole admin interface instead of the tree only. This way we can add a URL parameter ?lang=<lang> to /admin, which makes the specific language bookmarkable and reloadable. Changes to LangSelector.js
ENHANCEMENT Added fallback to ModelAsController->getNestedController() to fetch page with matching URLSegment but different language in case no page is found in the current language.
ENHANCEMENT Added helper methods to Translatable: getTranslation(), hasTranslation(), isTranslation(), findOriginalIDs()
ENHANCEMENT Getters and setters for Translatable->getOriginalPage() etc.
ENHANCEMENT Hooking Translatable into ModelAsController and ContentController initialization in order to call choose_site_lang()
ENHANCEMENT Simplified Translatable->augmentSQL(), augmentWrite() by not using auxilliary tables
ENHANCEMENT Showing clickable links for Translations in Translatable->updateCMSFields()
BUGFIX Modifying Hierarchy/SiteTree Children getters to accept optional "context" which can be used to set a language explicitly through the $Lang property, rather than implicitly reyling on the static Translatable::current_lang()
BUGFIX Fixed TranslatableTest to work with new datamodel
BUGFIX Temporarily disabled cookie/session selection in Translatable::choose_site_lang() until we have a good test suite for the side effects.
MINOR Added "untranslated" CSS styles to tree nodes and marking them as inactive/grey
