I assume this should have been "5.9" and adjusted accordingly. Feel free to change it if I misunderstood.

== New Experimental Features ==
* A `changelogv2` format has been introduced. It is not ready for use yet, but
will be used later to address some of the weaknesses of the current revlog
format.
* Initial experiment and support for `dirstatev2`, a new dirstate format that
addresses some of the weaknesses of the current dirstate format. Python + C
and Rust support are being implemented, but the Rust solution is the one
currently getting the attention for performance.
* Initial support for `rhg status`. `rhg` is the Rust wrapper executable for hg
that shortcuts some commands for faster execution speed.
== Bug Fixes ==
* Fixed a regression (in 5.9.1) introduced in 5.9 when cloning repos with
deep filenames
* Fixed detection of directories becoming symlinks, but only when using the
Rust extensions.
* Fixed ignore and include not composing in the Rust status
* `hg commit --interactive` now handles deselecting edits of a rename
* Fixed a case where `hg evolve` gives different results when interrupted
* Fixed a memory leak in phases computation
* `histedit` and `shelve` don't swallow errors when updating the working copy
anymore
* Improve error message when detecting content-divergence with a hidden
common predecessor
* No longer re-order parents in filelog, see issue6533
* Fix revisions affected by issue6533 on the fly during exchange
* Many Windows fixes for stability and py3 compatibility improvements
* Many other miscellaneous fixes
== Backwards Compatibility Changes ==
== Internal API Changes ==
The Dirstate API have been updated as the previous function leaked some
internal details and did not distinct between two important cases: "We are
changing parent and need to adjust the dirstate" and "some command is changing
which file is tracked". To clarify the situation:
* the following functions have been deprecated,
- `dirstate.add`,
- `dirstate.normal`,
- `dirstate.normallookup`,
- `dirstate.merge`,
- `dirstate.otherparent`,
- `dirstate.remove`,
- `dirstate.drop`,
- `dirstateitem.__getitem__`,
* these new functions are added for the "adjusting parents" use-case:
- `dirstate.update_file`,
- `dirstate.update_file_p1`,
* these new function are added for the "adjusting wc file" use-case":
- `dirstate.set_tracked`,
- `dirstate.set_untracked`,
- `dirstate.set_clean`,
- `dirstate.set_possibly_dirty`,
See inline documentation of the new functions for details.
* Additionally, the following have been deprecated:
- `urlutil.getpath` function
- `localrepository.updatecaches`' `full` argument
* The following have been removed:
- `revlog.revlogio` has been removed
