Here's a tracker to follow issues that really should be resolved before we switch to python3.6.
https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2ba87dec1a0f7d623796d17340068120d97ebfae This has broken a lot of deptrees, I cannot update any of my systems because there are plenty of packages that still don't support python3.6 This should be reverted until, at least, the packages maintained by python herd are ported, otherwise, sometimes, is an real hell to try to add support to apps and you encounter that you need to also add support to plenty of python packages (like, for example, flash-* stuff)
temporary reverted as https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=8b776b92e5db75a415a34393cc81e988dae4e545 I con confirm that it broke my stable systems terribly

Or even better via a news item as this likely will take its time to get fixed. I recently updated a system and knew before about the switch to 3.6 and had many rebuilds. Now wanted to do it on a second computer and didn't get the update. Spent half an hour trying to find the issue as I thought I had set Python targets somewhere, digged into the profiles which stated "Updated to python3_6" but targets were set to 3.5. Bad mirror? Seems no. Luckily a thread on gentoo-user titled "python 3.6" (that I ignored before) was on the top of my mailbox that mentions this subsequent revert.
Tracker or not, 3.6 is the default for a long time and 3.5 is gone.
