* Incompatible Lisp Changes in Emacs 26.1
+++
** Certain cond/pcase/cl-case forms are now compiled using a faster jump
table implementation. This uses a new bytecode op `switch', which isn't
compatible with previous Emacs versions. This functionality can be disabled
by setting `byte-compile-cond-use-jump-table' to nil.
+++
** Resizing a frame no longer runs 'window-configuration-change-hook'.
Put your function on 'window-size-change-functions' instead.
