CIDER 1.21 ("Gràcia")

Changes

• #3854: Use buttons for items in cider-ns-browser to allow clicking and evil's RET to navigate.
• Drop support for Emacs 27.
  • This was prompted by upstream deps dropping support for it.
• Remove deprecated cider-*-global-opts.
• Move Emacs Lisp code under lisp/ folder to improve the structure of the repo.
  • That's not a user-visible change, but might affect the packaging depending on how you're installing CIDER.

Bugs fixed

• #3853: Fix mangling of printed representations.
  • This was caused by a bug in nREPL, that was addressed in nREPL 1.5.2
