Can't update 1.7.19 -> 1.7.20

[Circlotron]

Using Mint Mate 17 32 bit.
I originally installed 1.7.19 using the following:
-------------------------
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine1.7
-------------------------
and it all worked just fine.
Now I want to update to 1.7.20
-------------------------
sudo apt-get update
sudo apt-get install wine1.7
[sudo] password for myname:
Reading package lists... Done

wine1.7 is already the newest version. <---------
The following package was automatically installed and is no longer required:
icoutils
Use 'apt-get autoremove' to remove it.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
-------------------------
1.7.20 had been out for 11 days now, so why doesn't it distinguish between 1.7.19 and 1.7.20?
Or is that not the right way to update Wine form the command line? Package manager is no help either.

Looks like they haven't built 1.7.20 packages. https://launchpad.net/~ubuntu-wine/+archive/ppa

As to why, ask the package maintainers. What and when to build is entirely up to them.
