My Mandriva Linux 2006 version works fine. It is a 64 bit version I downloaded from a FTP site.

Now I have downloaded 2007 version from FTP site. I downloaded 3 CDs. However, it seems a beta version. Will it corrupt my nicely working system? Because beta versions are said to be trial programs fraught with bugs. I would like to hear from you all on this.
Please read the following details.

Mandriva Linux 2007 Beta version "Tyr"

Tyr release notes

Release note for the third Mandriva Linux 2007 beta version

Linux 2007 Tyr is the third beta version for the Mandriva Linux 2007
release.

You can see the technical details at DistroChangelog.

Availability

This Beta is mainly available via two means. Firstly via the public
FTP and HTTP sites mirroring the Mandriva Linux repository. Check the
current development mirrors at CookerMirrors, the 2007 Beta tree is in
/devel/2007.0/. Second, the preferred way, via either the provided One
CDs (installable live CDs), or the intallation DVD or the two set of
three CDs installation CDs for i586 and x86_64. You will find the live
CDs and the installation CDs and DVD in the same mirrors as the cooker
one, in the /devel/iso/2007.0/ section.

Known Issues

* Network module b44 is not working properly
* Some menu entries are not yet displayed because the XDG migration
is not finished

Main changes

WARNING: Some One CDs have non-free (proprietary) drivers included, if
you do not want to use non free software, be careful to only use the
ISO images with the 'free' keyword included in their name.

The non-free drivers included are intended for hardware which cannot
work properly without proprietary drivers or firmware. These devices
include (but are not limited to) video cards, network cards and
modems. If you do not want to be obliged to use proprietary drivers to
run your computer properly, you should be careful to choose hardware
which is officially supported by free drivers.

Changes from 2007 beta 2

* New 3D desktop support (both with AIGLX and Xgl) and new tool to
configure it (drak3d)
* New One CD with 3D desktop support (AIGLX and Xgl, both on KDE and
Gnome, autodetection of the best 3D solution)
* The new rpmdrake is now included
* More applications migrated to XDG menus

Changes from 2006

* GNOME 2.16 RC 1
* Kernel 2.6.17 (based on 2.6.17.8, with ALSA 1.0.12 rc2, i965
support, and new kernel factorization: normal, enterprise and
legacy)
* KDE 3.5.4
* New 'Ia Ora' Mandriva Theme (still only included in GNOME)
* New VPN configuration tool (drakvpn)
* New Firewall to configure a redundant firewall with ucarp
(invictus-firewall)

Mandriva Linux 2007 Beta One CDs

There are seven different editions of the One CD for this beta, each
of which contains a different selection of supported languages. Due to
space constraints, most languages are only present on one of the seven
CDs. It is likely that the language repartition will change for future
betas. You can find a list indicating which languages are included on
each edition in the following description. However, once the live CD
is installed, you have the possibility to add new languages if you
configure an external Mandriva Linux 2007 urpmi source. The
installation DVD and 6xCD editions of the beta both contain all
supported languages.

Including as many languages as possible is very important to promote
Linux use in every country. If you are interested in helping improve
support for your own language, please consult TranslationTask. We will
do our best to find a way to create at least one version of a Mandriva
Linux product which includes support for your language.

One CDs include most of the needed stuff for a complete office and
internet desktop, OpenOffice.org, Mozilla Firefox, 3D desktop (XGL and
AIGLX with Compiz), network and hardware configuration tools and
drivers (the free version only includes free drivers).

If you are good at troubleshooting and fixing problems, then its ok to use a beta. For most people though, its not a good idea because many things can break. I installed the Mandriva 2007 development release a few weeks ago and it had lots of problems with the X server, aiglx and fonts. If you really want to try it out, I suggest you run it as a live cd or install it on a free partition.

Thanks reddazz

I am very bad at troubleshooting and I want to live without problems. I wouldn't install.

u shud only try ur hands at a beta version only if u are a power user or really like challenges, cause break at odd times,...
