-# 4.0.0 (unreleased)
-
-## Overview
-
-### Framework
-
- * Deprecate `SQLQuery` in favour `SQLSelect`
- * `DataList::filter` by null now internally generates "IS NULL" or "IS NOT NULL" conditions appropriately on queries
- * `Controller::init` visibility changed to protected
- * Initialising controllers now the responsibility of `Controller::doInit()`
- * `handleRequest`
-
-## Upgrading
-
-### Update code that uses SQLQuery
-
-SQLQuery is still implemented, but now extends the new SQLSelect class and has some methods
-deprecated. Previously this class was used for both selecting and deleting, but these
-have been superceded by the specialised SQLSelect and SQLDelete classes.
-
-Take care for any code or functions which expect an object of type `SQLQuery`, as
-these references should be replaced with `SQLSelect`. Legacy code which generates
-`SQLQuery` can still communicate with new code that expects `SQLSelect` as it is a
-subclass of `SQLSelect`, but the inverse is not true.
-
-### Update implementations of augmentSQL
-
-Since this method now takes a `SQLSelect` as a first parameter, existing code referencing the deprecated `SQLQuery`
-type will raise a PHP error.
-
-E.g.
-
-Before:
-
-	:::php
-	function augmentSQL(SQLQuery &$query, DataQuery &$dataQuery = null) {
-		$locale = Translatable::get_current_locale();
-		if(!preg_match('/("|\'|`)Locale("|\'|`)/', implode(' ', $query->getWhere())))  {
-			$qry = sprintf('"Locale" = \'%s\'', Convert::raw2sql($locale));
-			$query->addWhere($qry); 
-		}
-	}
-
-After:
-
-	:::php
-	function augmentSQL(SQLSelect $query, DataQuery $dataQuery = null) {
-		$locale = Translatable::get_current_locale();
-		if(!preg_match('/("|\'|`)Locale("|\'|`)/', implode(' ', $query->getWhereParameterised($parameters))))  {
-			$query->addWhere(array(
-				'"Locale"' => $locale
-			));
-		}
-	}
-
-
-### Update to Controller initialisation
-
-`Controller::init` is now protected, so any overloaded instances of this method need to have their visibility changed to
-`protected`
-
-Before:
-
-	:::php
-	public function init() {
-		parent::init();
-		
-		if (!Member::currentMemberID()) {
-			Security::permissionFailure($this);
-		}
-	}
-
-After:
-
-	:::php
-	protected function init() {
-		parent::init();
-		
-		if (!Member::currentMemberID()) {
-			Security::permissionFailure($this);
-		}
-	}
-
-Initialising controllers now need to be done with the `doInit` method.
-
-Before:
-
-	:::php
-	
-	$controller = ModelAsController::controller_for(Page::get()->first());
-	$controller->init();
-
-After:
-
-	:::php
-	
-	$controller = ModelAsController::controller_for(Page::get()->first());
-	$controller->doInit();
