+=== v1.7.0 === (18 April 2014)
+
+A major new version of ISPC with several language and library extensions and
+fixes in debug info support. Binaries for all platforms are based on patched
+version on LLVM 3.4. There also performance improvements beyond switchover to
+LLVM 3.4.
+
+The list of language and library changes:
+
+* Support for varying types in exported functions was added. See documentation
+  for more details.
+
+* get_programCount() function was moved from stdlib.ispc to
+  examples/util/util.isph, which needs to be included somewhere in your
+  project, if you want to use it.
+
+* Library functions for saturated arithmetic were added. add/sub/mul/div
+  operations are supported for signed and unsigned 8/16/32/64 integer types
+  (both uniform and varying).
+
+* The algorithm for selecting overloaded function was extended to cover more
+  types of overloading. Handling of reference types in overloaded functions was
+  fixed. The rules for selecting the best match were changed to match C++,
+  which requires the function to be the best match for all parameters. In
+  ambiguous cases, a warning is issued, but it will be converted to an error
+  in the next release.
+
+* Explicit typecasts between any two reference types were allowed.
+
+* Implicit cast of pointer to const type to void* was disallowed.
+
+The list of other notable changes is:
+
+* Number of fixes for better debug info support.
+
+* Memory corruption bug was fixed, which caused rare but not reproducible
+  compile time fails.
+
+* Alias analysis was enabled (more aggressive optimizations are expected).
+
+* A bug involving inaccurate handling of "const" qualifier was fixed. As a
+  result, more "const" qualifiers may appear in .h files, which may cause
+  compilation errors.

+Updating ISPC Programs For Changes In ISPC 1.7.0
+------------------------------------------------
+
+This release contains several changes that may affect compatibility with
+older versions:
+
+* The algorithm for selecting overloaded functions was extended to cover more
+  types of overloading, and handling of reference types was fixed. At the same
+  time the old scheme, which blindly used the function with "the best score"
+  summed for all arguments, was switched to the C++ approach, which requires
+  "the best score" for each argument. If the best function doesn't exist, a
+  warning is issued in this version. It will be turned into an error in the
+  next version. A simple example: Suppose we have two functions: max(int, int)
+  and max(unsigned int, unsigned int). The new rules lead to an error when
+  calling max(int, unsigned int), as the best choice is ambiguous.
+
+* Implicit cast of pointer to const type to void* was disallowed. Use explicit
+  cast if needed.
+
+* A bug which prevented "const" qualifiers from appearing in emitted .h files
+  was fixed. Consequently, "const" qualifiers now properly appearing in emitted
+  .h files may cause compile errors in pre-existing codes.
+
+* get_ProgramCount() was moved from stdlib to examples/util/util.isph file. You
+  need to include this file to be able to use this function.
