3  * `hg mv -A` can now be used with `--at-rev`. It behaves just like

     4    `hg cp -A --at-rev`, i.e. it marks the destination as a copy of the

     5    source whether or not the source still exists (but the source must

     6    exist in the parent revision).

     8  * New revset predicate `diffcontains(pattern)` for filtering revisions

     9    in the same way as `hg grep --diff pattern`.

    26  * `merge.update()` is now private (renamed to `_update()`). Hopefully

    27    the higher-level functions available in the same module cover your

    28    use cases.
