That will be hard to produce. :-) _My_ personal story is that I have Git-1.4.4.4 installed system-wide on repo.or.cz and follow git#next locally, and quite panicked when I was inspecting some repositories as root (using the system-wide Git) and these error messages popped up. This may become a similar experience for others on multi-user systems where people want to share work but don't realize that one of them has Git installed locally and the other one doesn't. We can save them the head-slapping and a bit of wasted life.

Out of interest, I did a simple statistics of HTTP user agents on repo.or.cz; the dumb access does not seem very widely used overally, it turns out. The stats begin at 19/May/2008:10:54:32 +0200. Here is the breakdown, counting unique clients only:

# zgrep '"GET /r/.*/info/packs' /var/log/apache2/repo-access.log* | egrep -v bot\|slurp\|Gecko\|Opera |
	cut -d " " -f 1,12- | sed 's/\.g[a-f0-9]*\(\.dirty\)*"/"/' | sort -u |
	cut -d ' ' -f 2 | sort | uniq -c | sort -rn | head -n 50
   1501 "git/1.5.4.3"	<- Ubuntu Hardy (heh.. is just that it?)
    278 "git/1.5.5.1"	<- RHEL5 (ditto)
    151 "git/1.5.2.5"	<- Ubuntu Gutsy
    133 "git/1.5.5.3"	<- ? (maybe Gentoo ~x86 for some time)
    125 "git/1.5.4.5"	<- OpenSUSE 11.0, FC9, Gentoo x86, Dapper backports
    104 "git/1.5.6"	<- Debian Lenny
     94 "git/1.5.5"
     66 "git/1.5.3.7"
     63 "git/1.5.5.4"
     63 "git/1.5.5.1015"
     55 "git/1.5.2.4"	<- OpenSUSE 10.3
     51 "Mozilla/4.0 (compatible;)"	<- huh?
     42 "git/1.5.3.8"
     37 "git/1.5.5.GIT"
     37 "git/1.5.3.5.2229"
     34 "git/1.5.6.1"
     33 "git/1.5.3.6"	<- Feisty backports
     31 "git/1.5.4.1"
     30 "git/1.5.6.2"
     20 "git/1.5.6.GIT"
     18 "git/1.5.3"
     17 "git/1.5.2.2"
     17 "git/1.4.4.4"
     15 "git/1.5.6.1.1071"
     14 "git/1.5.3.3"
     13 "git/1.5.4.4"
     13 "git/1.5.4"
     11 "git/1.5.6.1062"
     11 "git/1.5.5.2"
     10 "git/1.5.5.1.316"

(I also got two 1.4.4.2 (feisty?) fetches from one client. No older Git versions.)

So wrt. keeping backwards compatibility, this is not _very_ convincing, I admit. ;-)
