[Mageia-dev] Changelog entries - why not delimited by release/build?

[Christian Lohmaier]

Hi *,

I wondered about this for quite some time.. When you view the
changelog when updating your system, it is very hard to see what
actually did change in that new release.

For example the current cups update:
Version available: 1.5.4-1.1.mga2
currently installed: 1.5.4-1.mga2

Changelog:
       * So 16 Dez 2012 13:00:00 CET oden <oden> 1.5.4-1.1.mga2

        + Revision: 331722
        - P103: attempt to fix #8318 (some usb printers stopped working)
        - 1.5.4
        - sync patches and some changes from cauldron
        - P102: security fix for CVE-2012-5519 (upstream, redhat)
        - merge spec file changes from fedora to deal with the new
cups-files.conf file

          + guillomovitch <guillomovitch>
            - add upstream patches to fix #4673

          + tmb <tmb>
            - Require rpm-helper >= 0.24.8-1 for systemd support

        * Fr 27 Apr 2012 14:00:00 CEST tmb <tmb> 1.5.2-4.mga2

        + Revision: 233546
[....]

So what did actually change between 1.5.4-1.mga2 to 1.5.4-1.1.mga2?

This time there is a hint about a major version bump in an update, so
I can only assume the change is only "P103: attempt to fix #8318 (some
usb printers stopped working)"
(what does P# stand for btw? Is there a list of annotations used in changelogs?)

Why aren't changelogs separated by actual release?

ciao
