When I tried to answer a question (from other people) about why in 1.3
we need to explicitly declare ^:dynamic for a Var, I found I cannot
find an official document about this change from 1.2 (or older
version) to 1.3. I went to github (https://github.com/clojure/clojure/
blob/master/changes.md) but only found description like 1.1 Earmuffed
Vars are No Longer Automatically Considered Dynamic -- at first
glance I thought that the explicit declaration thing is only for
earmuffed Vars but when I tried it in a 1.3 REPL, I found we need to
explicitly declare all Vars to ^:dynamic if we want a rebinding.
Where can I find the official statement about this change (or other
similar changes)?
