Subject: Upgrade CPAN from 2.03-TRIAL to 2.04-TRIAL
X-Git-Tag: upstream/5.20.0~194
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=41b0043f16694f5080ec5888f9cec5e89b387f19;p=platform%2Fupstream%2Fperl.git

Upgrade CPAN from 2.03-TRIAL to 2.04-TRIAL

  [DELTA]

    2014-03-18  Andreas Koenig  <k@UX31A>

    * release 2.04-TRIAL

    * history of master branch was rewritten after Tour de France bughunting
    (Lyon #QA2014); apologies to all repository followers: the real history,
    as it actually went, is not worth being recorded in the master branch.

    * address #91706 and #86915: the 'force install' bug and the endless
    loop bugs reported in the two tickets are fixed (joined forces)

    * new configure option 'use_prompt_default' (David Golden)

    * add new dummy distros OptionalPrereq and CircularPrereq for testing
    recommends/suggests support

    * experimental recommends/suggests support (David Golden, Andreas Koenig)

    * enable hiding of directories in the distroprefs tree (suggested by
    Slaven Rezić)
