Magna Carta (alpha 4)

This release has been mostly about under-the-hood technical changes, described in this blog post.

These changes also made it possible to improve the end-user experience of Mainframe OS, notably:

• A standalone installation process for all supported platforms (Linux, macOS and Windows), that also supports notifying about Mainframe OS updates.
• Faster opening of Mainframe OS, with the additional ability to save the user's password using the underlying OS key management service.
• Updated documentation that should make it easier to get started with using Mainframe OS and developing applications.
