    [#946](https://github.com/libgit2/pygit2/pull/946)
    [#950](https://github.com/libgit2/pygit2/pull/950)

Breaking changes:

-   Now the Repository has a new attribute `odb` for object database:

        # Before
        repository.read(...)
        repository.write(...)

        # Now
        repository.odb.read(...)
        repository.odb.write(...)

-   Now `Tree[x]` returns a `Object` instance instead of a `TreeEntry`;
    `Object.type` returns an integer while `TreeEntry.type` returned a
    string:

        # Before
        if tree[x].type == 'tree':

        # Now
        if tree[x].type == GIT_OBJ_TREE:
        if tree[x].type_str == 'tree':

-   Renamed `TreeEntry._name` to `Object.raw_name`:

        # Before
        tree[x]._name

        # Now
        tree[x].raw_name

-   Object comparison is done by id. In the rare case you need to do
    tree-entry comparison or sorting:

        # Before
        tree[x] < tree[y]
        sorted(list(tree))

        # Now
        pygit2.tree_entry_cmp(x, y) < 0
        sorted(list(tree), key=pygit2.tree_entry_key)

    deprecates [Patch.patch]{.title-ref}
    [#790](https://github.com/libgit2/pygit2/pull/790)
    [#893](https://github.com/libgit2/pygit2/pull/893)
