On a page like this: https://luci-milo.appspot.com/buildbot/chromium.gpu.fyi/Linux%20Debug%20%28Intel%20HD%20530%29/982
Only CL names are shown in "All Changes:" section.

Seeing CL description and changed files, like in old UI https://build.chromium.org/p/chromium.gpu.fyi/builders/Linux%20Debug%20%28Intel%20HD%20530%29/builds/982 is very useful for finding which CL breaks the bot.
