+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 2/9] Blank the screen with color 0, add third color for failed
- logins
-
-- Adds another color in config.def.h, COLOR_INIT
-- Renames the colours from numerical ones to ones with meaningful names;
-  COLOR_INPUT for when there is content in the input buffer and COLOR_EMPTY
-  for when the input buffer has been cleared (backspaced or a failed attempt).
-- Ensures XFreeColors frees the right number of colours. This is now derived
-  from the size of `Lock->colors` rather than being an integer literal.
-- Makes slock exhibit the behaviour described by Markus
-
-The default colours are the same as the ones slock currently uses, with the
-exception of the new color, which I have set to red, as it indicates someone
-has either failed an attempt to unlock, or that they have entered input and
-erased it all.

+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.
