+*** Change of 'package-check-signature' for packages with multiple sigs
+In previous Emacsen, 't' checked that all signatures are valid.
+Now 't' only checks that at least one signature is valid and the new 'all'
+value needs to be used if you want to enforce that all signatures
+are valid.  This only affects packages with multiple signatures.

 *** New function 'package-get-version' lets packages query their own version.
 Example use in auctex.el: '(defconst auctex-version (package-get-version))'
