Zero Install for Windows 2.20.0 released

Hello all,

I recently published Zero Install for Windows 2.20.0
(https://github.com/0install/0install-win/releases/tag/2.20.0).

This version has some cool new features to speed up fetching new
implementations:

- .zip and .tar.* archives are now extracted while downloading without the
need for intermediate temporary files.

- Manifest digests are now calculated while extracting archives. This saves
time and reduces disk IO, because files don't need to be written to disk and
then read again.

Other improvements:

- Unix executable bits on Windows are now inferred from .manifest files.
This removes the need for separate .xbit files.

- Feed validation has been improved. This leads to clearer error messages
explaining which part of a feed cannot be processed.

As always, you can update to the latest version by running:

0install self update

You can also try this out on Linux and macOS, by running the cross-platform
(.NET-based) part of Zero Install for Windows like this:

0install run https://apps.0install.net/0install/0install-dotnet.xml run
https://example.com/some-feed.xml
