 ## Upcoming Changes

+## Version 1.4
+
+Implemented "IF", "ELSEIF", "ELSE", "ENDIF", and "INDEX" for templates.
+
+IF is used like: `{{{!IF Variable==SomeString}}}`.  
+Not equals can also be used: `{{{!IF Variable!=OtherString}}}`.  
+ELSEIF is used like: `{{{!ELSEIF Variable==AnotherString}}}`.  
+Not equals can also be used: `{{{!ELSEIF Variable!=AnotherOtherString}}}`.  
+ELSE is used like: `{{{!ELSE}}}`.  
+ENDIF is used like: `{{{!ENDIF}}}`.  
+INDEX is used like: `{{{!INDEX ArrayVar[2]}}}`.
+
+Implemented "FOREACH" and "ENDFOREACH" for templates.
+
+FOREACH is used like:
+
+    PATH=/
+    HTML='''
+        {{{!FOREACH ArrayVar}}}
+            {{{ArrayVar}}}
+        {{{!ENDFOREACH}}}'''
+    ArrayVar=FirstValue
+    ArrayVar=SecondValue
+    ArrayVar=ThirdValue
+
+For multiple variables to expand in FOREACH:
+
+    PATH=/
+    HTML='''
+        {{{!FOREACH ArrayVar!ArrayVarSecond!ArrayVarThird}}}
+            {{{ArrayVar}}}
+            {{{ArrayVarSecond}}}
+            {{{ArrayVarThird}}}
+        {{{!ENDFOREACH}}}'''
+    ArrayVar=FirstVarOnce
+    ArrayVar=FirstVarTwice
+    ArrayVarSecond=SecondVarOnce
+    ArrayVarSecond=SecondVarTwice
+    ArrayVarThird=ThirdVarOnce
+    ArrayVarThird=ThirdVarTwice
+
+Implemented nestable "IF" and "FOREACH" expressions in templates. In other
+words, there can be `{{{!IF}}}` inside other IF/FOREACH blocks, and vice versa.
+
 ## Version 1.3

 Fix internal erronous buffer declaration.
