Previously selectFromTable would simply try to select the composite field name. This expands the extraField name to include the children field names and uses CompositeDBField::writeToManipulation to generate the correct SQL for the queries.
This means that you dont have to worry about casting it
as HTMLText again when using the result in a template or other context
However in some situations code might be assuming it can
check with is_string, in which case you now need to use instanceof HTMLText
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
This allows DataList::create('SiteTree') as equivalent to Object::create('DataList', 'SiteTree'), without
having to have a create() function on DataList. Required for E_STRICT compliance.
DBField::prepValueForDB() and StringField::prepValueForDB() to ensure
the field value is escaped correctly for the database. This means
databases like MSSQL can introduce an "N" prefix (marking text as
unicode to be saved correctly) by overloading the
prepStringForDB method. MySQL, PostgreSQL and SQLite3
operate as usual.
