= 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

= Mercurial 6.7 =

As usual, a *lot* of patches don't make it to this list.

== New Features ==

 * 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

 * obsutil: sort metadata before comparing in geteffectflag()

 * crecord: drop calls to `curses.endwin()`

 * rust-index: don't use mutable borrow for head-diff computation

 * 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.
