Evolve 10.5.1 released

[Anton Shestakov]

We released a new version of the evolve extension: 10.5.1.

As usual, the release is available on PyPI and upgrade is recommended.

This is a bugfix release. The most notable changes are: more work on
fixup command that was introduced in the previous release, and a couple
of bug fixes. Evolve is no longer confused when trying to select the
latest successor in cases where a changeset was split and its child was
pruned, see https://bz.mercurial-scm.org/show_bug.cgi?id=6648. Evolve
with --dry-run flag used to update working directory in certain cases,
see https://bz.mercurial-scm.org/show_bug.cgi?id=6669, this was fixed.
There are also changes that should help Debian package maintainers; e.g.
it's now possible to use system cbor instead of the one we vendor.

Thanks to all the people involved:
