Question of Orca upgrade with final 2.24 version in Hardy?

[Hammer Attila]

Dear List!

Luke, you doed this repository with launchpad:
http://ppa.launchpad.net/accessibility-dev/ubuntu hardy main

When 2.24.0 GNOME and Orca coming out, possible replace Orca with this 
version official (stable version)?

Why ask I this question?
Hungarian blind users now using 2.22.3 GNOME and 2.22.3 Orca version, 
but 2.24.99-pre Orca version is lot of new features (better Firefox 
webbrowsing and better structural navigation, new tutorial messages 
function, better hungarian translations and bug fixes etc).

Ok, know, user please upgrade Intrepid, but Hardy is a long term support 
distribution release, but not upgrade GNOME 2.22 to 2.24 because it is a 
drastical change the distribution?
Or it is not true?

How can doing upgrade all users with Orca version only (official 
repository same for you repository) but stable version?
Or it is long and hard work, lot of mistakes, simplest upgrade with 
intrepid?

Thanks,

Attila
