It's not necessary better. The new behavior just broke my use-case. I don't have anything in my system what would react on KEY_MUTE and I used the functionality platform provides until it suddenly stopped working. I personally can live with new thinkpad_acpi. I'll probably update my configuration to react on the software button. But who else will get frustrated after update to v3.19? -- Kirill A.
