rHG32b527417ba3: relnotes: copy contents of "next" to "5.8" and clear "next"
Summary

The same procedure as every year^Wcycle.

Unlike previous cycles, I haven't actually recorded the copy because
we don't want to propagate further changes in "next" (from the stable
branch) to "5.8".

Hmm, this will conflict D10496 etc (which I assume are meant for the stable branch just like this patch is). I'm fine with that series or this patch getting queued first. Actually, take that series first since it touches the file several times (I'll just have to resolve the conflict once while @marmoute would have to resolve it several times).

I've taken @marmoute 's series first as you suggested, you can rebase yours now. Thanks for noticing!

relnotes/5.8

  • This file was added.
== New Features ==
* `hg purge` is now a core command using `--confirm` by default.
* The `rev-branch-cache` is now updated incrementally whenever changesets
are added.
* The new options `experimental.bundlecompthreads` and
`experimental.bundlecompthreads.<engine>` can be used to instruct
the compression engines for bundle operations to use multiple threads
for compression. The default is single threaded operation. Currently
only supported for zstd.
== Default Format Change ==
These changes affects newly created repositories (or new clone) done with
Mercurial 5.8.
* The `ZSTD` compression will now be used by default for new repositories
when available. This compression format was introduced in Mercurial 5.0,
released in May 2019. See `hg help config.format.revlog-compression` for
details.
* Mercurial installation built with the Rust parts will now use the
"persistent nodemap" feature by default. This feature was introduced in
Mercurial 5.4 (May 2020). However Mercurial instalation built without the
fast Rust implementation will refuse to interract with them by default.
This restriction can be lifted through configuration.
See `hg help config.format.use-persistent-nodemap` for details
== New Experimental Features ==
* There's a new `diff.merge` config option to show the changes
relative to an automerge for merge changesets. This makes it
easier to detect and review manual changes performed in merge
changesets. It is supported by `hg diff --change`, `hg log -p`
`hg incoming -p`, and `hg outgoing -p` so far.
== Bug Fixes ==
* gracefully recover from inconsistent persistent-nodemap data from disk.
== Backwards Compatibility Changes ==
* In normal repositories, the first parent of a changeset is not null,
unless both parents are null (like the first changeset). Some legacy
repositories violate this condition. The revlog code will now
silentely swap the parents if this condition is tested. This can
change the output of `hg log` when explicitly asking for first or
second parent. The changesets "nodeid" are not affected.
== Internal API Changes ==
* `changelog.branchinfo` is deprecated and will be removed after 5.8.
It is superseded by `changelogrevision.branchinfo`.
* Callbacks for revlog.addgroup and the changelog._nodeduplicatecallback hook
now get a revision number as argument instead of a node.
* revlog.addrevision returns the revision number instead of the node.
* `nodes.nullid` and related constants are being phased out as part of
the deprecation of SHA1. Repository instances and related classes
provide access via `nodeconstants` and in some cases `nullid` attributes.
