Why does do-release-upgrade on 12.04 system not find 14.04.1 upgrade? [duplicate]

I saw an article that 14.04.1 was released today so I went to update an LTS machine but it didn't find an update.

$ sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04.4 LTS
Release:    12.04
Codename:   precise

What's the criteria for getting upgrades for LTS releases?

Solution 1:

LTS releases are aimed at people who desire stability over the latest features. For this reason we want to establish that the next LTS release is stable before its made available.

This happens with the first point i.e. When we release Ubuntu 14.04.1

This happened today 25 July 2014 as you can see from this release announcement on the fridge.

In the next few days you will start seeing an option to upgrade when you run the Update Manager.

There is no urgent need for you to update yet however. Ubuntu 12.04 is supported till April 2017 and you can upgrade any time from when the Update manger first offers you 14.01 (some time in the next few days) till just before the current LTS release goes EOL.
