The second release candidate of the installer for Debian 9 "Stretch" has been released

Important change in this release of the installer
=================================================

* A major update of os-prober was included in this release. This
component is responsible for finding other operating systems so
that entries can be added to the bootloader's menu. This update
should fix serious bugs, some of which leading to file system
corruption, but might also trigger some regressions. As usual,
running "reportbug os-prober" from the installed system lets you
report any issues.


Improvements in this release
============================

* debian-installer:
- Bump Linux kernel version from 4.8.0-2 to 4.9.0-1.
- Adjust *.so files handling (#851790).
* os-prober:
- Improve logging of mounting and setting partitions to ro/rw.
- Use a read-only device-mapper entry when appropriate.
- Skip partition when FS type is LVM2_member (#853277).
- Make os-prober-udeb depend on grub-mount-udeb, and make
os-prober depend on grub-common, so that grub-mount is
consistently available (#776275).
- Fix detection of /usr partition as a GNU/Linux root partition
when /lib* directories are moved to /usr completely (#698733).
- Make the yaboot parser more tolerant (#674561).
- Call dmraid only once.
- Add os-release support (#794409).
- Work harder to avoid trying to mount extended partitions
(#784709).
- Drop " (loader)" suffixes on Microsoft operating systems
(#787418).
- For more improvements, see: #698598, #694668, #803155, #801631,
#851983.
