 * Helper varieties of ShadingSystem::Parameter() and ReParameter() that

+* `ShaingSystem::optimize_group()` now takes an optional parameter that
+  allows the caller to only do the optimize step without the JIT step.

-* testshade: Check that no leftover errors are in the TextureSystem or

+    - Build script finding of LLVM is now more robust to certain library
+      configurations of llvm, particularly where everything is bundled in
+      just one libLLVM without a separate libLLVMMCJIT. #976 (1.10.4/1.11.0)
+    - Support for LLVM 4 has been dropped. #981 (1.11.0)
+    - Simplified finding of flex/bison, rely more on CMake's built-in
+      flex/bison find packages. #977 (1.11.0)
+    - Verified that OSL can be built with Clang 8 and LLVM 8.0.
+    - When building against recent OIIO versions whose Sysutil supports
+      stack dumps, crashes in the command line tools (including testshade)
+      will print stack traces to aid debugging. #1019 (1.11.0)
+    - Improve finding of OpenEXR/IlmBase. #1022 (1.11.0)
+    - Fix problems when building against Qt 5.13 due to deprecated calls.
+      #1043 (1.11.0)
+    - Fixes for CI when using OIIO 2.1 master that has changed its own cmake
+      minimum to 3.12. #1065 (1.11.1)
+    - Improvement for how the build system figures out which LLVM static
+      libraries are needed. #1070 (1.11.1)
+    - Improvements in finding Partio. #1125 (1.11.5)
+    - Fixes to support Qt 5.15 (currently, osltoy is the only component that
+      uses Qt). #1204 (1.11.6)
+    - Better able to find LLVM when the system installation of LLVM has its
+      llvm-config named `llvm-config-64`. #1238 (1.11.7.1)
+    - Fixes for OIIO 2.2 which has eliminated use of tinyformat in favor of
+      always relying on fmtlib. #1242 (1.11.7.1)
 * A new build-time CMake variable `OSL_LIBNAME_SUFFIX` lets you optionally
   add a custom suffix to the main libraries that are built. (Use with
   caution.) #970 (1.11.0)
