This is from UKBA on the 'transitional arrangements':-
Those who, before 9 July 2012, have applied for initial or further leave under the rules in force prior to that date will, if they qualify for it, be granted leave under those rules and will continue to be dealt with under those rules through to indefinite leave to remain if they qualify for it (including those who have applied for leave as a fiancé(e) or proposed civil partner), subject to the requirement from October 2013 to pass the Life in the UK test and present an English language speaking and listening qualification at B1 level or above to qualify for settlement. The new criminality thresholds will also apply to such cases.
