+    
+    Details:
+    - Added setid call (to zero imaginary parts of diagonal elements) to

+
+    Tweaked behavior of herk, her2k for BLAS compat.
+    
+    Details:
+    - Updated herk_front() and her2k_front() to explicitly set the imaginary
+      components of the diagonal entries of C to zero after the computation
+      is complete. This is needed in case downstream applications read the
+      full diagonal entries (i.e., including imaginary part), which could, in
+      the absence of this modification, accumulate numerical error from
+      subsequent rank-k/rank-2k updates.
+    - Updated BLAS compatibility wrappers for herk and her2k to return early
+      if:
+        n == 0 || ( ( alpha == 0 || k == 0 ) && beta == 1 )
+      This also results in the imaginary components of diagonal entries NOT
+      being set to zero (see above), which is consistent with BLAS.
+    - Updated mkherm to use setid instead of an inlined loop over the
+      diagonal.

+
+    Added new level-1d operation: setid.
+    
+    Details:
+    - Defined a new level-1d operation, setid, which sets the imaginary
+      elements of an object's diagonal to a single scalar. This can be
+      useful, for example, when trying to make the diagonal of a Hermitian
+      matrix real-valued.

+    
+    Details:

+Date:   Mon Jul 14 11:24:36 2014 -0500
+
+    Changed order of zero dim / error checking.
+    
+    Details:
+    - Updated level-2 and level-3 internal back-ends so that the operation's
+      _check() function is called BEFORE any attempt to return early due to
+      the presence of zero dimensions. This ordering makes more sense because
+      (for example) object dimensions should match even if one of them is
+      zero. Previously, a dimension mismatch could result in an early return
+      with no error message.
+    - Updated bli_check_object_buffer() so that NULL buffers result in an
+      error only if the object is dimensionally non-empty (i.e., only if both
+      of the object's dimensions are non-zero). This allows BLIS operations
+      to be performed on dimensionally empty objects (i.e., where at least one
+      dimension is zero).
+    - Updated the error message associated with bli_check_object_buffer()
+      to mention the newly relaxed constraint mentioned above, vis-a-vis
+      non-zero dimensions.

+    
+    Details:
+    - Replaced "not yet implemented" error messages in dsdot() and sdsdot()

+      this log message will probably lead to some people learning of their
+      existence for the first time.)

+
+    Inserted gemv beta-scaling bug into compat layer.
+    
+    Details:
+    - BLAS has a peculiar bug (or feature) whereby calling gemv on a vector
+      y of non-zero length and a vector x of zero length results in no action.
+      Given that the operation is y := beta*y + A*x, many (most?) individuals
+      would expect vector y to still be scaled by beta. BLIS, when called
+      natively, handles these cases intuitively (with beta scaling).
+      Unfortunately, many BLAS test suites actually check for the way this
+      situation is handled. Therefore, we have decided to implement this "bug"
+      in the compatibility layer so as to provide "bug-for-bug" compatibility
+      with BLAS.

+
+    Added bli_info_*() query functions.
+    
+    Details:
+    - Added a new API family, bli_info_*(), which can be used to query
+      information about how BLIS was configured. Most of these values are
+      returned as gint_t, with the exception of the version string which
+      is char*.
+    - Changed how the testsuite driver queries information about how BLIS
+      was configured (from using macro constants directly to using the
+      new bli_info API).
+    - Removed bli_version.c and its header file.
+    - Added STRINGIFY_INT() macro to bli_macro_defs.h
+    - Renamed info_t type in bli_type_defs.h to objbits_t (not because of
+      an actual naming conflict, but because the name 'info_t' would now be
+      somewhat misleading in the presence of the new bli_info API, as the
+      two are unrelated).

+    - Changed bla_rotg.c and bla_rotmg.c to use bli_fabs() macro instead of
+      f2c's abs() macro for float and double cases.
+    - Thanks to Murtaza Ali for suggesting the two fixes above.
+    - Updated label of fnormv to normfv in testsuite/input.operations.

+
+    Defined _ukernel_void() wrappers to micro-kernels.
+    
+    Details:
+    - Added wrappers for micro-kernels so that users may invoke the
+      micro-kernels without knowing what the function names actually are.
+      This is useful when an application wishes to call the micro-kernel
+      from a shared library instance of BLIS, where the application may not
+      necessarily have the luxury of grabbing the micro-kernel name(s) from
+      C preprocessor macros at compile-time. Also, since the wrappers use
+      void* pointers, one's environment does not need to be aware of some
+      BLIS types such as scomplex and dcomplex. These wrappers now join the
+      level-1 and level-1f kernel wrappers, which pre-dated this commit.
+    - Removed the wrapper definitions and prototypes from the micro-kernel
+      test suite modules, and replaced calls to them with calls to the new
+      wrappers mentioned above.
