Forwarding to the current list. Here's my response: Hmm... I'm not crazy about it. I don't like the look of the box around the Linaro logo. I'd rather it be a solid color or the graduate should be changed so that it goes from the center out. As it is. its slightly distracting. ---------- Forwarded message ---------- From: Joey STANFORD <joey(a)linaro.org> Date: 8 March 2012 10:22 Subject: New artwork To: linaro-android <linaro-android(a)linaro.org> Zach, Some updated artwork for you and the team to play with.

New build naming convention

by Zach Pfeffer

So our current naming scheme is awful. staging- landing- tracking- ick ick ick We'd like to make this better, here's the idea: old new staging-vexpress-a9 ics-armlt-stable-gcc46-vexpress-a9 tracking-panda ics-tilt-tracking-gcc46-panda aosp-panda ics-aosp-stable-gcc44-panda staging-imx53 ics-freescalelt-stable-gcc46-imx53 panda-4.4 ics-tilt-upstream-gcc46-panda landing-snowball ics-igloo-stable-gcc46-panda landing-panda ics-omapzoom-stable-gcc46-panda, keep staging-panda ics-tilt-stable-gcc46-panda staging-origen ics-samsunglt-stable-gcc46-origen panda ics-kwg-upstream-gcc46-panda panda-4.4 ics-aosp-stable-gcc44-panda Its basically, <type of Android>-<kernel source>-<kernel type>-<toolchain version>-<target> Hopefully this will allow people to figure out what's what.
