+= Mercurial 6.7rc0 =
+
+/!\ These are **tentative** release notes for the upcoming Mercurial 6.7.
+Anything can be added or removed before the actual release.
+
+As usual, a *lot* of patches don't make it to this list.
+
+== New Features ==
+
+ * JSON templates can now use structured diffstat data
+ * Support rhg status --rev --rev
+ * The index for REVLOGv1 now has a Rust implementation
+ * Improved `hg censor`'s output
+ * censor: add a command flag to skip the head checks
+ * censor: accept multiple revision in a single call
+ * usage: add a `usage.repository-role` config
+ * branchmap: use mmap for faster revbranchcache loading
+ * crecord: enable search hotkeys (issue6834)
+ * hg-core: separate timestamp and extra methods
+ * annotate: limit output to range of lines
+ * unbundle: faster computation of changed heads
+ * Large improvements of some of the phases code (23950e39281f)
+
+== New Experimental Features ==
+
+ * Introduce `hg admin::chainsaw-update` for automation and *advanced* users
+
+== Bug Fixes ==
+
+ * templatekw: fix inconsistency of diffstat with diff.merge
+ * The endless stream of Python 3 cleanups continues
+ * Improved setup.py robustness
+ * Improved test suite robustness
+ * add: don't attempt to add back removed files unless explicitly listed
+ * statprof: handle `lineno == None` in more cases
+ * rust: fix cargo doc for hg-cpython
+ * rust-python-index: don't panic on a corrupted index when calling from Python
+ * debugindexstats: handle the lack of Rust support better
+ * matchers: use correct method for finding index in vector
+ * narrow: strip trailing `/` from manifest dir before matching it
+ * cext: fix potential memory leaks of list items appended with PyList_Append
+ * doc: document that labels must have a dot in them to have an effect
+ * debugformat: fix formatting for compression level
+
+== Backwards Compatibility Changes ==
+
+Users of the Rust extensions and/or `rhg` should be aware that the new Rust
+index can result in a performance degradation for push/pull on repositories
+*not* using `persistent-nodemap` (see `hg help config.format.use-persistent-nodemap`).
+
+If this is something that matters to you, please reach out to us as this is not
+an insurmountable obstacle. This is a choice base on the assumption that
+there are few people in this situation and our time should be spent on more
+pressing matters.
+
+== Internal API Changes ==
+
+ * 62913:498017baa34b "cleanup: remove some code scheduled to be removed after 5.9"

+ * Lots of refactorings to prepare for performance improvements and remove tech debt
