0.4.22 version 12 July 2007
===================================================================================================
Block method semantics was extended: one can use block($data) instead of block(NULL,$data)
to iterate current context. Set method can accept arrays with numerical keys to 
set several root iterations simultaneously. Basic template examples were added to php_info(). 
A couple of new tests were added. 

===================================================================================================
0.4.21 version 09 July 2007
===================================================================================================
Minor fetch bugfixes were made.

===================================================================================================
0.4.20 version 08 July 2007
===================================================================================================
Starting from this version Blitz "officially" supports lite variables assigning. One had to use
a "list" of arrays (array with numerical keys and array values) to set context iterations in previous 
versions. Now it's possible to use a "hash" of scalar/array values (array with string keys 
for variables or block iterations) for a single iteration - this makes the code much more clear. 
To have a single iteration of a context named "block", assigning a variable $var = "value", 
one can just say $data['block']['var'] = 'value' and then $View->set($data). This also worked 
in previos versions but in some cases like fetch this caused a segfault - now it's fixed. 
Additionally two minor bugs were fixed: current path is not iterated when iterating 
a nonexistent path, and there is no first empty iteration when the whole template is iterated 
cyclically by a root path '/'.

===================================================================================================
0.4.19 version 03 July 2007
===================================================================================================
New API methods getIterations/get_iterations and getGlobals/get_globals 
were added to get assigned template variables. Method alias setGlobals/set_globals 
for setGlobal/set_global was added to improve naming style (setGlobal/set_global still works). 
A bug in getStruct was fixed: nodes with errors are not returned. Alternative tags "<!--" and "-->" 
were extended by additional whitespace, new values are "<!-- " and " -->" (please convert your 
templates if you were using something like "<!--begin context-->").

===================================================================================================
0.4.18 version 23 June 2007
===================================================================================================
Bug #44 (naming conflicts) was fixed. getStruct()/get_struct() method was added to extend 
php_templates compatibility (getStruct method is a partial analog for the tmpl_structure function 
from php_templates extension, see samples/get_struct.php).

===================================================================================================
0.4.17 version 25 May 2007
===================================================================================================
Minor template parsing fixes were made (bugs## 40,41).

===================================================================================================
0.4.16 version 12 May 2007
===================================================================================================
Minor template parsing fixes were made.

===================================================================================================
0.4.15 version 1 May 2007. С праздником, товарищи! Коси и забивай.
===================================================================================================
A segfault which occurred when undefined variables were used in output wrapper was fixed. 
Minor changes in tests and examples were made.

===================================================================================================
0.4.14 version 28 Apr 2007
===================================================================================================
Documentation was updated. Minor php_templates compability fix: function calls without 
brackets are treated as variables with the same name by default. 

===================================================================================================
0.4.13 version 1 Apr 2007
===================================================================================================
Minor fixes in output wrappers were made (template syntax check was corrected,
ENT_NOQUOTES support added to "escape" method, default time for "date" method
is current time). Corresponding tests were updated.

===================================================================================================
0.4.12-1 version 31 Mar 2007
===================================================================================================
A segfault which occurred when variables are set into root context after clean/fetch 
operations was fixed.

===================================================================================================
0.4.12 version 31 Mar 2007
===================================================================================================
changes in "clean" method were made:
- "clean" removes all context iterations, not the latest one
- "clean" accepts second boolean parameter which says if blitz will throw PHP-warnings 
  when cleaning iteration is not found: $View->clean($path = '/', $warn_notfound = TRUE). 
  This parameter is TRUE by default.

Win32 compilation fixes (php_var_dump, php_parse_date) 

===================================================================================================
0.4.11 version 25 Mar 2007
===================================================================================================
A new output wrapper "date" was added: {{ date([FORMAT], $arg); }} will return a string formatted 
according to the given format string. When $arg is numerical, it is treated as UNIX timestamp integer. 
Otherwise $arg is parsed using internal PHP function "php_parse_date" which recognize a lot of date 
formats. Format string has the same conversion specifiers as PHP function "strftime".

Output wrapper "escape" was extended: {{ escape($arg) }} will use ENT_QUOTES quoting style by 
default, while {{ escape($a, "ENT_COMPAT") }} will use ENT_COMPAT.

===================================================================================================
0.4.10 version 19 Mar 2007
===================================================================================================
- Clean method was added: $Tpl->clean($path) cleans up context iterations and parameters which were
  made previously. Parameter $path is "root" by default ('/'): $Tpl->clean() with no parameter
  will unset all template varibales and iterations.
- Minor parsing fixes were made (long HTML comments treated as alternative tags
  could cause "lexem is too long" warning since 0.4.4 version).

===================================================================================================
0.4.9. version 17 Mar 2007
===================================================================================================
- minor parsing fixes were made (context name for alternative END-tag is optional without 
any syntax warning)

===================================================================================================
0.4.8. version 13 Mar 2007
===================================================================================================
- non-brackets format method fix: {{ test }}

===================================================================================================
0.4.7 version 11 Mar 2007
===================================================================================================
- segfault on alternative context parsing fixed (HTML comments started with 
non-alpha-numeric characters)

===================================================================================================
0.4.6 version 27 Feb 2007
===================================================================================================
- syntax warning for HTML comments in alternative context format 
  mode (<!-- BEGIN ctx --> ... <!-- END ctx -->) was fixed 

===================================================================================================
0.4.5 version, 25 Feb 2007
===================================================================================================
- internal escape output wrapper was added: {{ escape($a); }}, 
  escape($a) works exactly like htmlspecialchars($a, ENT_QUOTES);

===================================================================================================
0.4.4 version, 11 Feb 2007
===================================================================================================
- [VERY IMPORTANT] lower/upper case policy changed. 
  varible and context names are case sensitive, method names - not.
- commonly used context format compatibility added: <!-- BEGIN ctx --> ... <!-- END ctx -->
- other minor fixes
