+ * transaction: run abort callback in all cases
+ * transaction: quietly rollback if no other changes than temporary files
+ * debugrebuilddirstate: double check that no transaction is open
+ * dirstate: do not write an empty dirstate just for backup

+ * mq: properly take the wlock during the full qfold operation
+ * dirstate: invalidate the dirstate change on transaction failure
+ * status: fix post status writing

+ * dirstate: avoid transaction backup/restore if we do not hold the lock
+ * rollback: explicitly skip dirstate rollback when applicable

+== Backwards Compatibility Changes ==

+== Internal API Changes ==
+
+ * Many APIs around the dirstate have been made much stricter with regards to

+ * In both cases, you should get loud complaints in your tests if you do
+   something wrong.
+
+== Miscellaneous ==
+
+ * pullbundle support no longer requires setting a server-side option,
+   providing a .hg/pullbundles.manifest according to the syntax specified in

+ * merge: disable the whole filesystem access loop if [_realfs] is false
+ * merge: cache the fs checks made during [_checkunknownfiles]
+ * rust: use `logging_timer` instead of `micro_timer`
+ * rust: run `cargo clippy`
+ * makefile: add `cargo clippy` to tests if cargo is available
+ * heptapod-ci: add `clippy` to the CI
