No, just download 14.04.1 It has lots of good bug fixes, like bug 1309458, it fixes the ubiquity installer crashing when clicking release notes, and bug 1315866 with the usb creator, it's a workaround for Python Qt4 being sucky.

You can see the full list of changes here.

It is different to the Windows 8 + 8.1 system, in that this was planned to be "public". Normally, windows just give their releases "secretly", without revealing they are upgrading to what is called a "point release".

14.04.1 hasn't really got any new features, it just comes with all the updates you have to do if you download 14.04 included.

So for clarification, you can either download 14.04 + lots of updates, or just 14.04.1. It has them all included already. 14.04 won't have the bugs, but 14.04 is more work to get patched. ^{_{Kudos @CharlesGreen}}

When 14.04 is fully updated it identifies as 14.04.1 - they are identical. So I installed 14.04, and when I run

lsb_release -a

I get some irrelevant details (for this example) and then:

...

Distributor ID: Ubuntu

Description:    Ubuntu 14.04.1 LTS

Release:    14.04

Codename:   trusty

So you can see that the Descriptor is 14.04.1 LTS, even though I installed 14.04 (when it was first released).
