OH! Mighty FOSE Gods! I pray to you on my knees and wonder why 1.1b2 says my unworthy Steam FO3 1.4 instalation is an unknown version (1.4.0.6). May You, Allmighty, answer my question, plea?
It looks like there are actually two different versions of 1.4.0.6, one with a hash of 0x03ABCAA0, and one with a hash of 0x56492499. The first one was pushed out to all regions except Austria/Germany, this is the one that is currently supported. However, this second build is slightly newer (was built at a later time, not sure if there are any actual improvements) and was pushed out to Austria/Germany and apparently Steam sometime today.
Since the amount of time required to support each unique patch version is very large, we try and keep the number of supported patches to a minimum while supporting the maximum number of users. This recent development has made things a bit difficult, as the user base is now divided among 1.0.0.15 and the two versions of 1.4.0.6.
First off, we'll be dropping support for 1.1.0.35 as it doesn't offer any improvements over 1.4.0.6, plus patches for that version are widely available. Secondly, we'll be waiting a few days for the DLC to be released to see if Bethesda releases another patch unifying the 1.4.0.6 versions (please?). At that point we will need to reevaluate the situation and see what we can support. In the worst case scenario we will probably need to end up supporting all three versions.
This is good news for people in Austria/Germany, and not good news for us. People will need to hold on for a few days so we can see what Bethesda does regarding this situation. In the meantime, if you are using Steam, turn off auto-update temporarily.
