 	* Bugfix: variables, structures, functions changed their names from
 	  *GOST3411* to fully-qualified *GOST34112012*
-	
+
 	* Bugfix: API: GOST34112012Init() now operates on allocated memory.
 	  Previously, memory allocation for context has been done with
 	  GOST34112012Init() call - this guarantee proper alignment for context's
 	  members.  As for now, alignment is done with ALIGN keyword in object
 	  declaration and GOST34112012Init() does not allocate any byte of memory.
-	
+
 	* Bugfix: API: GOST34112012Final() now returns digest in memory pointed by
 	  second argument.  Context member "hexdigest" not used anymore thus
 	  abandoned.  It is up to calling application to present digest in

 	  substitution by Pi[] while generating multiplication lookup table.
 	  Lookup table arranged in a such way totally eliminates the need to do
 	  whole S-cycle in LPS.
-	
+
 	* Feature: use SSE4.1 instructions set in LPS if available.
 
 	* Feature: multiplication lookup table is now statically precomputed in
 	  header file and is in constant memory.
-	
+
 	* Bugfix: rewrite GOST3411Update() function to implement streaming mode
 	  when processing large amount of data.
-	
+
 	* Bugfix: rename round2() and round3() to stage2() and stage3()
 	  respectively.
-

 	* Bugfix: in auto configuration probes: delete temporary files.

 	* Feature: with code optimization above, performance on 32-bit systems
 	  greatly improved and is now about as fast as with 64-bit systems.

 	* Bugfix: encryption function E inlined to compression g to avoid

 	* Feature: performance optimization in LPS: hint compiler to use eight
 	  registers instead of union buffer.
-	
+
 	* Feature: performance optimization in permutation P: rotate matrix by
 	  cyclic right shifting bits in source matrix columns to rows in
 	  destination matrix.
-	
+
 	* Feature: as result of previous two optimizations: replace LPS macros
 	  with improved macros XLPS.
 
 	* Bugfix: improve constant table C presentation to avoid runtime
 	  conversion in key generator K.
