I guess an example of this is the "at" package, which has:

AT_VERSION = release/3.1.23
AT_SITE = https://salsa.debian.org/debian/at.git
AT_SITE_METHOD = git

but we would probably want the version to be just "3.1.23", like is
tracked at https://release-monitoring.org/project/127/.

So indeed, I see two possible directions here:

 (1) Keep the <pkg>_VERSION semantic as it is today, and add a separate
     <pkg>_UPSTREAM_VERSION variable (or some other name) that holds the
     upstream version. This would give:

     AT_UPSTREAM_VERSION = 3.1.23
     AT_VERSION = release/$(AT_UPSTREAM_VERSION)

     With this, no need to change anything in the package
     infrastructure, we just need <pkg>_UPSTREAM_VERSION be extracted
     by support/scripts/pkg-stats, which is can trivially do instead of
     extracting <pkg>_VERSION.

     This approach also has the advantage that the name of the tarballs
     stored on disk doesn't change, which means all the DL_DIR contents
     + sources.b.o content remain identical.

     Of course, the package infrastructure defines
     <pkg>_UPSTREAM_VERSION to <pkg>_VERSION if there's no
     <pkg>_UPSTREAM_VERSION value defined for a given package.

 (2) As suggested by Victor, add a separate variable that tells the Git
     download logic what is the actual tag/version to fetch, i.e:

    AT_VERSION = 3.1.23
    AT_GIT_COMMIT = release/$(AT_UPSTREAM_VERSION)

Perhaps option (1) is the easiest ? But it has the drawback that
<pkg>_VERSION doesn't contain just the actual version, but like we do
today, some possibly semi-random stuff in addition to the version (like
"release/1.2.3" or "foo-1.2.3).

I don't see a gap-madam-bin-maxi package in Buildroot. I am missing
something ?

Kodi has two different entries in release-monitoring.org:

 https://release-monitoring.org/project/5511/, which has only the
 version, but seems to be outdated

  https://release-monitoring.org/project/20547/, which has the version
  + codename, and seems to be updated

So it looks like we should use the second one, and therefore keep the
code name ?

Best regards,

Thomas
