改进了标签替换方式，不需要递归进用替换，效率提升，也不用再限制标签嵌套层数。

Browse Source 
1. 兼容原来所有的标签功能和用法，已 对正则进行了优化，标签库和内置的普通标签可以使用一样的边界符，比如都用"{}"，只要不重名不会相互干扰，这样这些标签就可以和html标签区分开。

 2. 模板支持多级继承。C继承B，而B又继承了A，C中的block会覆盖B和A中的同名block。

 3. include标签支持多层嵌套，可以传变量。如：
include file="Public/nav" selected="{$id}"
 在Public/nav模板用[selected]得到的是[$id}被解析后的值，而在3.2版中这样的写法是不能正确得到{$id}的值的。

 4. 增强了.语法的应用范围
 {$user.name.$group.name} 解析后是 <?php echo $user['name'].$group['name']; ?>
 {:substr($varname.aa, $varname.bb)} 解析后是 <?php echo substr($varname['aa'], $varname['bb']); ?>
 .语法在各个标签中都可以使用，$a.b.c这样的形式都能正确解析成$a['b']['c']

 5. 增加了一些新的语法
 {$varname.aa ?? 'xxx'} 表示如果有设置$varname则输出$varname,否则输出'xxx'。 解析后的代码为： <?php echo isset($varname['aa']) ? $varname['aa'] : '默认值'; ?>
 {$varname?='xxx'} 表示$varname为真时才输出xxx。 解析后的代码为： <?php if(!empty($name)) echo 'xxx'; ?>
 {$varname ?: 'no'} 表示如果$varname为真则输出$varname，否则输出no。解析后的代码为： <?php echo $varname ? $varname : 'no'; ?>
 {$a==$b ? 'yes' : 'no'} 前面的表达式为真输出yes,否则输出no， 条件可以是==、===、!=、!==、>=、<=

 6. 对if标签及foreach也加了一些更简洁的用法
{if condition="表达式"}
{if (表达式)}
{if 表达式}
这三种写法结果是一样的
{foreach $list as $v} 解析后是最简洁的，只一个foreach语句
{foreach name="list" item="v“} 这僦是原来的写法，解析后foreach外层会多一if判断，item换成id也可以
{foreach name="list" id="v" key="key" index="i" mod="2" offset="2" length="5"}
volist上的功能，foreach都有，只是volist默认会带上一些参数，而foreach需要指定这些参数才会生效
