It seems that emacs-orderless in Guix wasn't really updated to 1.0,
only the version field was changed.

That's not enough, the hash in (sha256 (base32 [...])) needs changing
as well.

And when updating an untagged revision to a tagged release, we usually
drop the outer let form, and use the value from version field for
commit.

For example, the original definition:
--8<---------------cut here---------------start------------->8---
(define-public emacs-orderless
  (let ((commit [...]))
    (package
      (name "emacs-orderless")
      (version [...])
      (source
       (origin
         (method git-fetch)
         (uri (git-reference
               (url "https://github.com/oantolin/orderless";)
               (commit commit)))
         (file-name (git-file-name name version))
         (sha256
          (base32 [...]))))
      [...])))
--8<---------------cut here---------------end--------------->8---

would be changed to:
--8<---------------cut here---------------start------------->8---
(define-public emacs-orderless
  (package
    (name "emacs-orderless")
    (version "1.0")
    (source
     (origin
       (method git-fetch)
       (uri (git-reference
             (url "https://github.com/oantolin/orderless";)
             (commit version)))           ; <- see here
       (file-name (git-file-name name version))
       (sha256
        (base32 [...]))))                 ; <- hash is changed as well
    [...]))
--8<---------------cut here---------------end--------------->8---

BTW the hash can be obtained with `guix hash' [1]:
--8<---------------cut here---------------start------------->8---
git clone https://[...] emacs-orderless

cd emacs-orderless
git checkout 1.0

guix hash -rx .
--8<---------------cut here---------------end--------------->8---

Would you like to get familiar with the process by going through the
way [2] to make your first contribution? ;)

I can send a patch if you prefer, and it may take a few days to get
the change into Guix.

Thanks
