 ### New minimum dependencies and compatibility changes:
 
 * Note: it is likely that by the time it is released, OSL 1.14 will require
-  Imath >= 3.1.
+  Imath >= 3.1, Python >= 3.7, C++ >= 17, gcc >= 9.3.
 
 
-### OSL Language and oslc compiler (for shader writers):
+### OSL Language, standard library, and oslc compiler (for shader writers):
+  - Fix the subsurface_bssrdf parameters to conform to MaterialX. [#1823](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1823) (by Christopher Kulla) (1.14.1.0)
 
 
 ### ⛰️  API changes and new ShadingSystem features (for renderer writers):
+* The big switch to `ustringhash`: To better accommodate GPU execution, and to
+  make the code and techniques less divergent between CPU and GPU code paths,
+  we have changed the runtime representation of strings from `ustring` to
+  `ustringhash` -- which is still a 64 bit token, but rather than the address
+  of the unique characters, which may change from run to run and harm the
+  OptiX/CUDA PTX cache performance, it is the deterministic hash of the
+  characters. Thus, not just the runtime, but all of the interfaces of
+  RendererServices and other APIs that the renderers use to set up and
+  communicate with the ShadingSystem, now have been changed to expect
+  ustringhash instead of ustring.
+  [#1732](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1732) (by Steena Monteiro) (1.14.0.0)
+* Add API for building interpolated getter free functions.
+  [#1765](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1765) (by Thibault Vergne) (1.14.0.0)
+* Switch `shade_image()` to use current OIIO::paropt [#1843](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1843) (1.14.1.1)
 
 
 ### 🚀  SIMD batched shading mode
+  - *batched*: Codegen bug for compref with varying index [#1776](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1776) (by Alex Wells) (1.14.1.0)
 
 
 ### 🚀  OptiX GPU rendering
+  - Fix NVPTX TargetMachine leak, etc. [#1763](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1763) (by Tim Grant) (1.14.0.0)
+  - Fix GPU interpolated param initialization [#1791](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1791) (by Chris Hellmuth) (1.14.1.0)
+  - Add `lazytrace` ShadingSystem option to avoid combinatoric optixTrace
+    inlining: when enabled, run layers with trace ops unconditionally at the
+    start of shader evaluation. This costs some potential performance in cases
+    where the trace layer would never be evaluated, but removes all the
+    compilation penalties that the inlining was presenting.
+    [#1815](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1815) (by Chris Hellmuth) (1.14.1.0)
 
 
 ### 🐛/🔧  Internals: fixes, improvements, and developer concerns
+  - Mute partio error prints [#1774](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1774) (by olegul) (1.14.1.0)

+  - Print closure missing error message at compile time instead of run time.  [#1781](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1781) (by sfriedmapixar) (1.14.1.0)
+  - Make isconnected() work with downstream renderer "connections." [#1782](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1782) (by sfriedmapixar) (1.14.1.0)
+  - *int*: Change OSL_CONSTEXPR14 to constexpr [#1805](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1805) (1.14.1.0)
+  - Remove unnecessary ustring lookup [#1824](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1824) (by Chris Hellmuth) (1.14.1.0)

 ### 🏗  Build/test/CI and platform ports
 
 * CMake build system and scripts:

+    OSL will need to be build with C++17, too. [#1797](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1797) (1.14.1.0)
+  - Eliminate boost as a dependency: [#1802](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1802) (by Christopher Kulla) (1.14.1.0) [#1808](https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/pull/1808) (by Christopher Kulla) (1.14.1.0)
