+Release 0.5.4 - Jul 21, 2011
+----------------------------
+* Several fixes related to arrays of structs, and structs containing
+ other structs.
+* Fixed arrays of closures.
+* Removed support for old LLVM 2.7, nobody seemed to be using it any more.
+* Changed the definition of dict_find() to return -1 for an invalid
+ dictionary, to distinguish it from 0 meaning that the query failed but
+ the dictionary itself was valid.
+* Make array parameters safe to convert to constants during runtime
+ optimization.
+* Support derivatives in pointcloud searches.
+* Fixed several runtime optimizer bugs.
+* Fixed a bug where environment() calls with an optional "alpha" parameter
+ that has derivatives was overwriting memory.
+* Fixed code generation bug for a*=b and a/=b.
+* Automatically initialize all local string variables to NULL, to avoid
+ bad pointers for uninitialized strings.
+* Bug fix: dict_value() wasn't properly marking its argument as writable.
+* Automatic range checking of array and component access.
+* Fix uninitialized derivatives for pointcloud().
+* Speed up getattribute() calls by caching information about failed
+ getattribute queries in the ShadingContext.
+* Fix to constant folding of gettextureinfo: a failed lookup should not
+ fold, because we want the error to occur in shader execution, not during
+ optimization.
+* Refactor, clean up, and comment testshade.
+* oslc now gives an error on non-void functions that fail to return a value.
+* Fixed implementation of area() that could generate an assertion.
+* Fix escape sequences in string literals: we were handling it correctly
+ for printf-like format strings, but not other string literals.
+* break and continue now work properly (just like in C/C++).
+* You can now return from anywhere in a user function (multiple times if
+ you want), just like C/C++, and are no longer restricted to the only
+ return statement being the last statement of the function.
+* New include file for shaders: patterns.h. Now, it only includes a handy
+ 'wireframe()' function, but will expand for other useful things.
+* New function: int getmatrix(from,to,M) is like the matrix(from,to)
+ constructor, but returns a success value so a shader can tell if the
+ named coordinate systems failed to be found by the renderer.
+
+
+Release 0.5.3 - Apr 19, 2011
+----------------------------
+* Fix missing derivatives for sign() function.
+* Fix closure color type size (crashes).
+* Fix bug with environment() when passed "alpha" pointers with derivatives.
+* Improve error messages for getmessage/setmessage to catch the most
+ common sources of non-deterministic behavior.
+* Bug fix when constant-folding gettextureinfo().
+* Fix mismatched prototype for subsurface() closure.
+* Texture errors encountered in shader constant folding are now properly
+ reported to the renderer.
+* Allow functions to have array parameters of unspecified length.
+* Fix subtle bug related to lifetime analysis of variables in loops (led
+ to incorrect optimizations).
+
+
+Release 0.5.2 - Mar 14, 2011
+----------------------------
+
+* Windows: use boost::wave instead of external cpp; various other Windows
+ compilation fixes.
+* texture & environment now take an optional "interp" parameter that
+ overrides the interpolation/filtering method (valid arguments:
+ "smartcubic", "cubic", "linear", "closest").
+* Bug fixes to getmessage() and its handling of derivatives, which includes
+ a slight RendererServices API change.
