-Subject: [PATCH 1/7] Simplify the oom-taming-function
-
-There really is no need to source a defined variable from a linux
-header. The OOM-rank ranges from -1000 to 1000, so we can safely
-hardcode -1000, which is a sane thing to do given slock is suid and
-we don't want to play around too much here anyway.
-
-On another notice, let's not forget that this still is a shitty
-heuristic. The OOM-killer still can kill us (thus I also changed
-the wording in the error-message. We do not disable the OOM-killer,
-we're just hiding.

-Subject: [PATCH 3/7] No need for usage()
-
-There are 2 arguments why -v and -h are broken:
-
-	1) if you are running off git, -v will show the last stable
-           release, effectively making this option useless.
-           people running stable versions leave open an attack surface
-           this way in case there are vulnerabilities found.
-           99% of the people are also using package managers to keep
-           their software up to date, instead of running $TOOL -v to
-           check how old it is.
-        2) -h is a sad excuse for not just looking at the manual page
-           (man 1 slock). Given we accept a post_lock_command, we can't
-           be as liberal and just intercept certain flags.
-
-I changed the manpage to reflect this change.

-Subject: [PATCH 7/7] clear passwords with explicit_bzero
-
-Make sure to explicitly clear memory that is used for password input. memset
-is often optimized out by the compiler.
-
-Brought to attention by the OpenBSD community, see:
-https://marc.info/?t=146989502600003&r=1&w=2
-Thread subject: x11/slock: clear passwords with explicit_bzero
-
-Changes:
-
-- explicit_bzero.c import from libressl-portable.
-- Makefile: add COMPATSRC for compatibility src.
-- config.mk: add separate *BSD section in config.mk to simply uncomment it on
-  these platforms.
