 * The `builtin_zeromq` and `builtin_cppzmq` build options that were deprecated in ROOT 6.40 are now removed.
 * The ROOT **auth** package together with `TVirtualAuth` and `TROOT::GetListOfSecContexts()`, and the **authenticated sockets** (`TSocket::CreateAuthSocket()`) feature are now removed following deprecation in ROOT 6.40.
 * The `TSSLSocket` class is now removed following deprecation in ROOT 6.40.
+* The bindings to the R programming language that are enabled with the `r=ON` or `tmva-rmva=ON` build options (`TRInterface`, RMVA, and friends) are removed, following deprecation in ROOT 6.40. Their maintenance is no longer justified, given the broader adoption of the scientific Python ecosystem. Users who still rely on R from C++ are encouraged to call R directly via https://cran.r-project.org/package=RInside, which is what the ROOT bindings were using internally.
