* NEWS: Mention the new primitive sha1 and the removal of sha1.el.
*** New function `special-variable-p' to check whether a variable is
declared as dynamically bound.
+** Emacs integers have a wider range on typical 32-bit hosts.
+Previously, they were limited to a 30-bit range (-2**29 .. 2**29-1).
+Now, they are limited to a 62-bit range (-2**61 .. 2**61-1), the
+same as on 64-bit hosts. This increased range comes from the Emacs
+interpreter using 64-bit native integer types that are available
+on typical modern 32-bit platforms. Older 32-bit hosts that lack
+64-bit integers have the same 30-bit range as before.

** pre/post-command-hook are not reset to nil upon error.
Instead, the offending function is removed.
