@@ -56,11 +56,25 @@ The following people have contributed to this new version:
 
 * Behaviour change: the behaviour of `TChain::SetBranchStatus` has been aligned to the one of `TTree::SetBranchStatus`. In particular, when `SetBranchStatus` is called to deactivate all branches, a subsequent call to `TChain::SetBranchAddress` would override the previous instruction and activate that single branch. Instead `TTree::SetBranchAddress` respects the rule imposed by `SetBranchStatus`. If a user needs to activate only one or more branches, they should call `SetBranchStatus("brName", true)` on each branch that needs to be active in the TChain, like it was already necessary for a TTree. See https://github.com/root-project/root/pull/19221 for more details.
 
+### RNTuple
+
+* The parallel writer is now part of the public, stable API. The `RNTupleParallelWriter` and the closely related `RNTupleFillContext` moved from the `ROOT::Experimental` to the `ROOT` namespace.
+
 ## Math
 
+### Minimizer interface
+
+* The function `double ROOT::Math::Minimizer::GlobalCC(unsigned int ivar)` was changed to `std::vector<double> ROOT::Math::Minimizer::GlobalCC()`, always returning the full list of global correlations.
+  This change was needed because global correlations are not unconditionally computed and cached in the minimizer anymore. Only computing them when calling `GlobalCC()` avoids unneeded overhead when global correlations are not required.
+
 ### Minuit2
 
 * Behavior change: building ROOT using `minuit2_omp=ON` option no longer enables OpenMP parallelization by default. One has to call now additionally GradientCalculator::SetParallelOMP().
+* The functionality of the `FCNGradAdapter` got absorbed into the `FCNAdapter`. This also means that the `FCNGradAdapter.h` header is gone.
+* The `ROOT::Minuit2::FCNAdapter` is no longer templated and now handle only functions with this exact signatures:
+  * `double(double const *)` for the wrapped function
+  * `void(double const *, double *)` for the gradient
+  The advantage of this restriction is that the `FCNAdapter` can now also wrap any Python function that respects this interface.
