I don't know who maintain those changelogs, but WOW, thanks for this great detailed and methodical piece of work.

Indeed, KN is absolutely awesome.

Could anyone comment on the state of power management in Linux? Are we up to par with OSX and Windows yet?

Depends on the hardware and the amount of effort you put in. If you stick to purely Intel chips (cpu, gpu and wifi) if you spend the 5 minutes it takes to get powertop happy then you end up with equivalent battery life to windows. (Basing this on thinkpad t440 and thinkpad t450).

On my AMD APU laptop, I have been unable to get battery life to be similar to windows.

I see there's support for the new Radeon RX480. I've been thinking about picking up a Radeon card. Can anyone speak to their experience of Radeon support on Linux and whether or not you think it's a good idea?

The kernel driver for newer AMD cards is developed and open sources by AMD itself . For the user land, you have choice between the open source driver, Mesa, or the proprietary one, AMDGPU-PRO.

If you want to follow the advancement of Linux graphics stack (while having reasonable graphic performance), AMD is your choice. This is where the exciting new stuff, like Wayland, DRI3 etc. happens. The NVIDIA proprietary driver indeed has amazing performance, but is falling behind on this regard.

By default it is pretty bad. But if you install powertop and tlp you should be good. I get pretty good battery life on my Thinkpad this way.

Make sure you also checkout TLP since you have a Thinkpad.

The open source drivers/cards were solid for a good while on my old computer but I bought a new one in May and I got actual hardware level PCI errors with two different AMD cards on the Intel X99 chipset (within seconds of booting I would start getting error correction messages in my dmesg and the computer would hang within hours). I managed to stop the errors with kernel flags (pcie_aspm=off or pci=nommconf, either seemed to stop them) but my system was still completely unstable as the drivers/cards eventually went nuts regardless.

I bought an nVidia card and didn't have to touch anything and it's completely stable (in the same exact PCI slot).

I might try AMD again in a year or two as I prefer their model of actually supporting and writing open source drivers in contrast to the scummy nVidia whose cards now require a signed firmware that they won't release to the open source community after we got the reverse engineered open source drivers (well, they did release one now for the 9xx series after they released the 10xx series).
