The latest revision of the Code of Conduct removes the phrase “Be kind and friendly" entirely.
What was the rationale?
"Be kind and friendly" was replaced with "Be inclusive and respectful" in an attempt to "build a more welcoming and inclusive community".
This doesn't mean that we shouldn't be kind or friendly anymore though. The Code of Conduct still mentions "(un)friendly" in four places and "kind(ness)" in three.
As the announcement says, replacing the specific phrasing is not "a change to our policy" but a "clarification".
