I just pushed an update to the shr-testing repository. How to upgrade 
and what has changed?

--------------------------------------------------------------
Make big upgrades work
--------------------------------------------------------------
This upgrade will unfortunately require manual attention. Why? opkg 
downloads all upgrades to /tmp (which is in RAM), so for big upgrades 
your RAM will be full even before it starts upgrading.

There are 2 solutions for this:

    1. Only install one package at a time, calling opkg multiple time. 
This is quite easy and described here: 
http://trac.shr-project.org/trac/wiki/opkg#Installonepackageatatime
    2. Create a swap file that allows to swap out the downloads on the 
SD card. I recommend this anyway: 
http://trac.shr-project.org/trac/wiki/swap#Createaswapfile. If you are 
afraid that your SD card will die soon because of this, I don't think so 
and they are cheap anyway, so if you need to buy a new one every 2 
years, what the heck.

--------------------------------------------------------------
Remove SHR-TODAY
--------------------------------------------------------------
Before starting the upgrade do "opkg remove -force-depends shr-today". 
Opkg *should* be removing this automatically, however according to some 
reports opkg failed to do so (due to opkg stupidness), and keeping 
shr-today seems to cause weird lockups. So get rid of it in advance.

--------------------------------------------------------------
Safety tipp: screen session
--------------------------------------------------------------
- Do run this upgrade (as in every upgrade) in a screen session. My FR 
display froze during the upgrade (access through ssh still worked)
- It's a big upgrade unfortunately which takes some time. All kernel 
modules and all the efl stuff seems to have been bumped.

--------------------------------------------------------------
What is new:
--------------------------------------------------------------
- Plenty of changes to the shr phone apps...
- Dimming is now done with a  dim phase rather than the simple on/off. 
Timeouts can be set for the Idle and Idle_dim timeouts. To make these 
changes persistent, modify the values in /etc/frameworkd.conf
- python-based shr-today is no more. It is now rewritten in C and 
integrated into the shr UI. It's reportedly faster than the old lock screen.

Bugs that I have seen:
- The new idle screen does not show the signal strength for me
- During the opkg upgrade process my phone suspended and this aborted 
the upgrading.... Annoying, I know. I now tap on the screen while 
updating which is pretty silly but.... Of course, what you should be 
doing is to automatically request the CPU resource while running updates 
using this technique: 
http://trac.shr-project.org/trac/wiki/opkg#Preventsuspendwhileupgrading

To sum it up: if you see mysterious screen hangs, you have still 
shr-today installed and/or running.
