+- [Soft disable incremental compilation][94124]
+
+This release disables incremental compilation, unless the user has explicitly
+opted in via the newly added RUSTC_FORCE_INCREMENTAL=1 environment variable.
+This is due to a known and relatively frequently occurring bug in incremental
+compilation, which causes builds to issue internal compiler errors. This
+particular bug is already fixed on nightly, but that fix has not yet rolled out
+to stable and is deemed too risky for a direct stable backport.
+
+As always, we encourage users to test with nightly and report bugs so that we
+can track failures and fix issues earlier.
+
+See [94124] for more details.
