-	debian:
-		- show percentage of results in the last 24/48h (h01ger)
-		- switch python database backend to SQLAlchemy (Valerie)
-		- vary build path everywhere except when testing stretch (h01ger) - FIXME: explain why + expectations…
-some notes for writing this FIXME:
-enable build path variation for unstable and experimental
-	[00:50] <      h01ger> | so, more thinking brought me to: enable build path variation for exp. and sid, disable it for testing. besides being more logical and keeping the higher percentages (testing
-          is more reproducible than sid…) this has another advantage: we keep the less varying diffoscope output available (for packages which vary outside buildpath) which should make analysis
-          easier. and debian can decide whether
-[00:50] <      h01ger> |  we want to keep build pathes in .buildinfo files or ...
-[00:50] <      h01ger> | ... not…
-[00:51] <      h01ger> | and probabyl we as debian should keep them, and we as reproducible debian project should test with build path variation…
-[00:51] <      h01ger> | and maybe then we should do two kinds of rebuilds: with a different path than the original archive build and (only) if that fails, with the same path
-[00:53] < HW42> sounds good
-[00:53] <      h01ger> | because besides academia we also have another goal: enable users to indipendantly verify builds. and if they only can do this in /home/holger, than this is not so good, but
-          maybe acceptable with s#/home/holger/#/tmp/buildd/#g

+Debian related:
+- show percentage of results in the last 24/48h (h01ger)
+- switch python database backend to SQLAlchemy (Valerie)
+- vary build path varitation for *unstable* and *experimental* for all architectures. (h01ger) 
+
+The last change probably will have an impact you will see: your package might become unreproducible in *unstable* and this will be shown on [tracker.debian.org](https://tracker.debian.org), while it will still be reproducible in *testing*.
+
+We've done this, because we think reproducible builds are possible with arbitrary build pathes. But: we don't think those are a realistic goal for *stretch*, where we still recommend to use ´.buildinfo´ to record the build patch and then do rebuilds using that path.
+
+We are doing this, because besides doing theoretical groundwork we also have a practial goal: enable users to indipendantly verify builds. And if they only can do this with a fixed path, so be it. For now :)
+
+For future reference, when we enabled build path variation on Saturday, August 20th 2016, the number for *unstable* were:
+
+
+
+	suite		all 	reproducible 	unreproducible	ftbfs		depwait		not for this arch blacklisted
+
+	unstable/amd64	24693 	21794 / 88.2%	1753 / 7.1%	972 / 3.9%	65 / .2%	95 / .3%	10 / 0%
+	unstable/i386	24693 	21182 / 85.7%	2349 / 9.5%	972 / 3.9%	76 / .3%	103 / .4%	10 / 0%
