Problem migrating an extension from 2.20 to 2.22

["Charles-Henri d'Adhémar" <cdadhemar gmail com>]

Hello,

I have developed an extension for epiphany 2.20, tabforeground,
referenced at http://live.gnome.org/Epiphany/ThirdPartyExtensions.

It is probably one of the simplest extension since it makes tabs being
opened in the foreground instead of background.

The python code for epiphany 2.20 was as simple as that :

#!/usr/bin/env python
import gtk
import epiphany

def attach_tab(window, tab):
    window.jump_to_tab(tab)
# End python script

Since epiphany 2.22 I have the following error :

** (epiphany:12364): WARNING **: Python code for 'attach_tab' failed to execute
Traceback (most recent call last):
  File "/home/chicha/.gnome2/epiphany/extensions/tabforeground.py",
line 24, in attach_tab
    window.jump_to_tab(tab)
AttributeError: 'epiphany.Window' object has no attribute 'jump_to_tab'

It seems the API has changed in 2.22.

A quick look to
http://library.gnome.org/devel/epiphany/2.22/EphyWindow.html
http://library.gnome.org/devel/epiphany/2.20/EphyWindow.html
Highlight that the method (and many others) jump_to_tab as disappeared.

Also please notice that some other extensions such the sample-python
one do not work anymore either.

Is this a bug ? If not where can I find a documentation for the new
API, please ?
Thank you very much for your help !

Cheers,
Chicha
