I used Sage v. 5.0 for the first time in a while and couldn't connect to the notebook. I received the message: Firefox can't establish a connection to the server at localhost:8000.
I was still able to use Sage from the command line, but decided to install v. 5.11 to see if that would fix my problem.
In fact, it did; and now the notebook opens at localhost:8080.
Does anyone know the reason for this?
8000 or 8080 are arbitrary default choices. This default choice changed when the notebook became flask-based (see this ticket). You can specify the port you want as follows:
from Sage command line:
notebook(port=8888)
or from a shell:
sage -notebook port=8888
IIRC, the default port was changed in keeping with the official/unofficial suggestions for port numbers. See Wikipedia :)

This was just a change decided on with one of the notebook upgrades, it's not a bug. I'm not really sure about the rationale, though I think that 8000 was more popular so it was better to use 8080.
