+Most of the packages we failed to check did so for reasons unrelated to this
+release (they could not be installed in the check environment, e.g. missing
+Bioconductor dependencies).
+
+However, the following packages failed specifically because of the updated
+TBB ABI. They link, directly or transitively, against 'Rfast' or
+'stringfish', which were themselves compiled against the previous version of
+TBB and so reference symbols (such as 'tbb::task') that oneTBB 2022.0 no
+longer provides:
+
+ * via 'Rfast':       CompositionalRF, DER, kernreg, Rfast2
+ * via 'stringfish':  qs2, rxode2
+
+These will resolve once 'Rfast' and 'stringfish' are reinstalled / rebuilt
+against RcppParallel 6.0.0, which we expect to happen when CRAN rebuilds the
+reverse dependency chain. No source changes are required in those packages.
+
+(One further package, 'multinma', failed to check due to the compiler being
+killed for exceeding memory during compilation, which is unrelated to this
+release.)
