Subject: bug#67955: [PATCH] Add use-package-vc-prefer-newest user option
Date: Thu, 21 Dec 2023 19:13:21 +0100

[Message part 1 (text/plain, inline)]

Hi,

as stated in the subject, the attached patch adds a
'use-package-vc-prefer-newest' user option. When non-nil, packages
installed with use-package's :vc keyword will default to the latest
commit, instead of the latest release.

Thanks
Tony
