As jameskyle said in the commit message you quoted below, wxWidgets  
was downgraded back to 2.8.9 for compatibility reasons. I don't have  
more details than that.

I'm not certain why people think that's a pity. Yes, an epoch line  
will need to remain in wxWidgets forever, but why is that a problem?

The epoch can stay at 1 until someone wants to do another downgrade.  
MacPorts basically concatenates the numbers epoch_version_revision,  
so we had the sequence:

0_2.8.9_0
0_2.8.10_0
1_2.8.9_0

If we later update to 2.8.10 again after resolving whatever the  
issues were, it will be:

1_2.8.10_0
