Metacello changes in Pharo 3?

Hi,
it seems Metacallo changed in Pharo 3 compared to Pharo 2.
First thing i noticed was that a Configuration does no longer seem to be supposed to subclass from Object but from ConfigurationOf?
Are there other changes? Where can i learn about them? Is there an official documentation that describes the Metacello Version in Pharo 3?

Best regards, Martin.

AFAIK that is not a requirement, maybe just a suggestion/option, but configurations subclassed from Object definitively still work in Pharo 3.x

Hi,

I don't think there is a doc explaining differences between Metacello and Metacello 2 (also known as Metacello Preview) that is now used in Pharo 3.0.

But here is the doc for Metacello 2: https://github.com/dalehenrich/metacello-work/blob/master/docs/MetacelloUserGuide.md

You can also use Versionner to edit configurations in Pharo 3 (in the tools menu). Versionner doc: http://chercheurs.lille.inria.fr/~demarey/Tech/Versionner

Regards,

Christophe.
