A lot of things have been implemented since the eight, and last Alpha development release of the Debian Stretch Installer, but the most important changes outlined in the announcement for the RC1 build are the revert of the switch to merged-/usr as default setting for debootstrap and disablement of Debian Pure Blends support. Noteworthy changes in the first Release Candidate of the Debian GNU/Linux 9 “Stretch” Installer include HTTPS (Secure HTTP) support by using new ca-certificates and GNU wget udebs, use of fonts-dejavu-udeb as default font, use of fonts-noto-hinted-udeb font package for the Sinhalese language, and bump of Linux kernel to version 4.8.
