[chandler-users] Upgrading from Chandler 0.7.3 (or earlier) to 0.7.4

[Grant Baillie]

Hi, all

I've just posted the note below on the Chandler 0.7.4 downloads page.   
Thanks to people who pointed this out (in IRC or bug reports). I'll be  
working on a fix.

Important Note if you're upgrading from an earlier release
----------------------------------------------------------

Unfortunately, there is a Bug[1] in Chandler 0.7.4 where the  
application does not detect that your repository needs to be upgraded  
This causes the application to fail to launch, usually after it  
displays an “Internal Program Error” dialog that ends with something  
like:

AttributeError: 'MissingClass' object has no attribute 'readValue'

To work around this, please follow the Data Migration[2] instructions  
to export your data and reload it into a shiny, new, clean repository.
