 External Dependencies
 ---------------------
 
-* Clad now works with clang-8 to clang-18
+* Clad now works with clang-10 to clang-20
 
 
 Forward Mode & Reverse Mode
 ---------------------------
-*
+
+* Improved handling of non-differentiable annotated types
+* Support `static_assert`.
+* Improved to-be-recorded (TBR) analysis.
+
 
 Forward Mode
 ------------
-*
+
+* Added support for `Useful Analysis` for more efficient derivative computation.
+* Custom derivative resolution now leverages Clang's `CallExpr` infrastructure
+  for correctness and compatibility.
+* Improved diagnostics for mismatched custom derivative signatures.
+* Enhanced handling of real-valued parameters only.
+
 
 Reverse Mode
 ------------
-*
+
+* Enabled static scheduling for constructor pullbacks.
+* Reworked `reverse_forw` naming and logic consistency.
+* Improved support for `std::shared_ptr`, `std::weak_ptr`, and complex
+  value-type parameters.
+* Support added for custom derivatives for STL iterators.
+* Static-only scheduling for pullbacks is now the default (excluding Hessians
+  and special cases like error estimation).
+* Improved support for rvalue references.
+
 
 CUDA
 ----
-*
+
+* Tape now supports CUDA builds and works with nvcc.
+* Recalculation support for CUDA built-in index functions (threadIdx, etc.)
+
 
 Error Estimation
 ----------------
-*
+
+* The error estimation framework has been updated to maintain singleton objects
+  per request, ensuring more consistent handling.
+
 
 Misc
 ----
-*
+
+* More descriptive stack traces for diagnostics.
+* Improved support for polymorphism and virtual functions in user demos.
+* A benchmark comparison script has been added.
+* The SmallPT ray tracer demo has been revised and fixed.
+* Added -version and improved --help usability.
+* Godbolt link included in documentation.
+* Reworked time reporting -- detailed performance information is shown when the
+  env variable `CLAD_ENABLE_TIMING` is set or passed `-ftime-report`.
+* Handle custom derivatives ahead of the differentiation process improving the
+  overall system robustness.
+
