			<div class="{{@ctr%2?'odd':'even'}}">{{@val}}</div>
		</repeat>
*	NEW: Axon/Jig/M2 afind() method for returning all records that match
	specified criteria as an array of associative arrays (instead of an
	array of objects)
*	NEW: <include> template directive now allows if="{{@expr}}" attribute for
	inserting a sub-template subject to the boolean value of specified
	expression

	should specify the PHP file name, e.g.

		F3::route('GET /about','about.php');
	At runtime, the framework will load pages/about.php when the GET /about
	route is received
*	Pipe (|), semi-colon (;) or comma (,) may now be used as separators for
	route() and input() function chains, IMPORTS and AUTOLOAD paths

	now responsible for sanitizing data via scrub() or input()
*	Change in behavior: scrub() and input() do not auto-convert to HTML
	entities anymore

	of deletion criteria; if not specified, criteria used in last load()
	statement is used

*	Bug fix: Incorrect handling of PHP tags in grab()
*	Bug fix: User-defined functions in F3 templates

*	Template syntax when using ICU-formatted strings in dictionaries:
		{{@stringvar//time()}} for F3 templates
		<?php echo $this->get('stringvar',time()); ?> for PHP templates
*	diacritics() is now a framework variable; Default Latin translations will
	be merged with any user-defined DIACRITICS once Web::slug() is called

	containing arrays

*	Template engines optimized
*	Bug fix: Routing side effects caused by extraneous spaces in config()

*	Minor code refactoring

2.0.0-b9
*	NEW: <loop> template directive:

		</loop>
	PHP equivalent:
		<?php for ($i=1;$i<$j;$i++): ?>
			<span><?php echo $i*2; ?></span>
		<?php endfor; ?>
	An optional step="{{1}}" attribute may be specified
*	NEW: UTF plug-in - a handy replacement for common mbstring functions

	PDO late-binding/lazy-loading

	callback function

	punctuation

	fast as regular PHP templates
*	Change in behavior: Template tokens MUST now use {{@var}} format

*	mset() now adds a variable prefix if a 2nd argument is specified

*	Minor code refactoring

2.0.0-b6

		F3::set('abc->y',array());
		F3::set('abc->y.1','hello');
		F3::set('abc->y.2',
			function() {
				return 'world';
			});
		print_r(F3::get('abc'));
*	DB framework variable is now instantiated automatically, e.g.:
		$db=new DB('sqlite:/data/test.db');
		$db->sql('SELECT * FROM mytable;');
		print_r($this->get('DB'));
	As a result, no reference to $db is necessary when creating a new
	Axon:

	Note however that Axon constructor's 2nd argument is required when
	working with multiple databases
*	dump() method for displaying HTML-friendly PHP expressions

		$project->load('project_id="f3"');
*	Template tokens can now be applied to class names in dynamic route
	handlers
*	Minor code refactoring

*	slug() is now filesystem-friendly
*	Template tokens for dynamic route handlers
		F3::route('GET /@token','{@PARAMS.token}');
		F3::route('GET /page/@action','Page->{@PARAMS.action}');
*	Bug fix: clear() session handling

2.0.0-b3
*	NEW: PROTOCOL framework variable; return value: 'http' or 'https'
*	Recursive replacement of framework variable variables in arrays
*	Axon erase() method now has an argument to prevent accidental deletion

	afterSave(), beforeErase(), afterErase(), beforeSync(), afterSync()
*	LANGUAGE/LOCALES auto-detection
*	Minor bug fixes

2.0.0-alpha

*	Base class stripped to the bare minimum (framework variables, routing,
	cache engine, error handling); Everything else is a plug-in - including
	the template engine
*	NEW: Object mode
		$app=require 'base.php';
		$app->route('GET /',
			function() {
				echo 'Hello, world!';
			}
		);
		$app->run();
*	NEW: Routing now supports new syntax for object instantiation
		F3::route('GET /','Main->home');
	instead of:
		F3::route('GET /',array(new Main,'home'));
	which allows $this-> prefix to be used to access framework methods
	(in the above example, Main class should extend F3instance)
*	NEW: Fatal errors caught by error and exception handlers
*	Procedural code support dropped (IMPORTS and routing chains); F3 is now
	strictly object-oriented
*	Axon/M2 find() now returns Axon/M2 objects (instead of arrays)
*	Template engine now allows access to properties of framework variables
	containing objects:
		$foo=new stdClass;
		$foo->phrase='99 bottles of beer';
		F3::set('myvar',$foo);
	To display the properties, use the syntax: {@myvar->phrase}
*	Framework variables defined as anonymous functions:
		F3::set('func',
			function($a,$b) {
				return $a.', '.$b;
			}
		);
	Template engine now interprets token as expected:
		{@func('hello','world')}
*	RELEASE variable dropped; DEBUG has been expanded instead:
		0 - suppress stack trace (for production use)
		1 - normal stack trace (noise removed)
		2 - detailed trace
		3 - verbose
