Mercurial 6.7.2

Exceptional release following a large performance regression when
cloning.

We are setting up automated benchmarks to reduce the likelihood of
regressions of the sort from happening in the future.

    phases: avoid a potentially costly dictionary interation in some case
    phases: update the phase set as we go during retract boundary
    bundle2: make the "hgtagsfnodes" part advisory

Mercurial 6.7.1

Exceptional release following a crash found in delta code that can
be triggered with complex repository shapes.

    delta-search: fix crash caused by unbound variable
    sshpeer: fix path when handling invalid url exception
    subrepo: fix normalizing paths with scheme

Log message:
py-mercurial: update to 6.7.

= Mercurial 6.7 =

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

 * 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)
 * rust-filepatterns: export glob_to_re function

== 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

 * rust-index: don't use mutable borrow to computed filtered heads

== 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.
