Version 1.0-beta1

This is the first beta for ppb-vector v1.0.
We expect this beta to become version 1.0 in a week or so.

What's new since v1.0a3

We automated our release process (#161, #170) to build and upload new versions to Github and PyPI (currently, test.pypi.org).

What's new since the last stable release (v0.3)

There were breaking changes:

• Vectors are now immutable, as implemented by @dataclass(frozen=True) (#106)
• Vector2 was renamed to Vector (#149)
• Making subclasses of Vector now isn't supported (#149)

For new features, see the release notes for:

• v1.0a3;
• v1.0a2;
• v1.0a1;
• v0.4.0rc1.
