Evolve 10.4.0 released

[Anton Shestakov]

We released a new version of the evolve extension: 10.4.0.

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

This is a feature release. The most notable changes are: evolve will
now produce the same result regardless of revision numbers when
resolving content-divergence; an annoying topic bug that sometimes
prevented various history-rewriting commands from completing with a
KeyError was fixed. See
https://bz.mercurial-scm.org/show_bug.cgi?id=6500 for details. Also
compatibility with Mercurial 4.6 was dropped in this release.

## Evolve: 10.4.0

  * evolve: use a more stable criteria for picking p1 when solving
    content-divergence (most recent evolution will be used)
  * evolve: drop the deprecated --unstable, --divergent and --bumped
    flags, they were replaced by --orphan, --content-divergent and
    --phase-divergent respectively a long time ago
  * evolve: remove experimental.obshashrange.lru-size docs, that config
    option didn't do anything for a long time
  * evolve: use precheck function from Mercurial 5.9+ when available,
    mostly affects error messages and exit codes

  * next: add an --abort flag

  * evolve, topic, pullbundle: drop compatibility with Mercurial 4.6

## Topic: 0.23.0

  * topic: don't cache .topic() of memctx instances, as that could
    produce KeyError: b'topic' during some rewrite operations
    (issue6500)
  * topic: drop old code for working with amends on ancient hg versions
    (~3.6)
