Hi release team,
please review the following bug-fix update for inclusion into the next
stable point release. Full debdiff is attached.
Cheers,
Stefan
apache2 (2.4.10-10+deb8u6) jessie; urgency=medium
* Fix race condition and logical error in init script. Thanks to Thomas
Stangner for the patch. Closes: #822144
* Remove links to manpages.debian.org in default index.html to avoid
broken robots doing a DoS on the site. Closes: #821313
* mod_socache_memcache: Increase idle timeout to 15s to allow keep-alive
connections. Closes: #803035
* mod_proxy_fcgi: Fix wrong behavior with 304 responses. Closes: #827472
* Correct systemd-sysv-generator behavior by customizing some parameters.
This fixes 'systemctl status' returning incorrect results.
Closes: #827444
* mod_proxy_html: Add missing config file mods-available/proxy_html.conf.
This is intentionally not enabled during upgrade, to make it less
likely to break existing setups. It will be enabled by a a2dismod/a2enmod
cycle, though. Closes: #827258
