sslutil: add support for clients to set TLSv1.3 as the minimum protocol AFAICT, all of the TLS versions are supported by the server without doing any explicit work, and there's only a `devel` config to specify an exact version on the server side. Clients would also use TLSv1.3 if available, but this prevents the server from negotiating down. This also causes "tls1.3" to be listed in `hg debuginstall`, even though it was previously supported (if the Python intepreter supported it- IDK if there's a good way to proactively test for and show future protocols without requiring manual updates like this). The v1.3 tests are nested inside the v1.2 tests for simplicity. The v1.2 blocks already assume v1.0 and v1.1 support, so this seems reasonable for now. If/when the older protocols start getting dropped, this will have to be reworked anyway.

= Mercurial 6.7.4 =

Exceptional release following a critical regression causing possible data loss
in certain conditions:

 * inline-changelog: fix a critical bug in write_pending that delete data (3cf9e52f5e27)
 * inline-changelog: fix pending transaction visibility when splitting (1721d983dd6d)

Other changes in this release:

 * exchange: fix locking to actually be scoped
 * chistedit: change action for the correct item
 * rust-status: sort the failed matches when printing them
 * hooks: add a prewlock and a prelock hooks
 * bookmark: fix remote bookmark deletion when the push is raced

= Mercurial 6.7.3 =

/!\ This release contains a bug causing possible data loss, use 6.7.4 instead.

 * setup: display return code information about failed `hg` call
 * bundle-spec: properly identify changegroup-less bundle
 * bundle-spec: properly parse boolean configuration as boolean
 * matchers: fix the bug in rust PatternMatcher that made it cut off early
 * match: fix the "visitdir" method on "rootfilesin" matchers
 * match: fix the rust-side bug in visit_children_set for rootfilesin matchers
 * match: strengthen visit_children_set invariant, Recursive means "all files"
 * wireprotoserver: ensure that output stream gets flushed on exception
 * re2: make errors quiet
 * dirstate-v2: add check of parent/child nodes being related when writing
 * dirstate-v2: check that root nodes are at the root before writing
 * rust-cpython: don't swallow the dirstate error message
 * rust: blanket implementation of Graph for Graph references
 * Various fixes to `admin::verify`

= Mercurial 6.7.2 =

/!\ This release contains a bug causing possible data loss, use 6.7.4 instead.

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 =

/!\ This release contains a bug causing possible data loss, use 6.7.4 instead.

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 =

/!\ This release contains a bug causing possible data loss, use 6.7.4 instead.

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

== 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.
