"After several delays the beta 2 version of Mageia 5 is finally out! You can find more information here.

But, it seems that yet again we need to postpone the Mageia 5 release.

Due to various difficulties with EFI boot, grub 2 and a few other things, we need a little more time. Only a few members of our QA team have EFI-based machines, so if you do have such equipment please test Beta 2 and report your experience.

Our QA, Packagers and ISO teams are working around the clock to bring us all a stable and secure release, but they still need to work out a few kinks.

Therefore, we are planning one more Beta release before the release candidate. So the final timeline looks like this:

Beta 3 – February 3
RC – February 24
Final release – March 10

We’re sorry for the inconvenience and thank you for your patience and understanding, and in case you were wondering if there’s anything you could do to help, just ask the teams!

We need as many people as possible to try this beta in order to identify any remaining problems. Please report any problems that you experience in the forums, mailing lists or, preferably, in bugzilla. Also don’t forget to check the errata."
