The fifth alpha release of the installer for Debian GNU/Linux 10 Buster is available

Important change in this release
================================

The Debian Installer team is happy to report that the Buster Alpha 5
release of the installer includes some initial support for UEFI Secure
Boot in Debian's installation media.

This support is not yet complete, and we would like to request some
help! A detailed article with more background about Secure Boot and
with a pointer to instructions on how to test and report findings has
been published:
