Description
After the migration from bugs.python.org to GitHub issues is completed, blurb should be updated so that GitHub IDs are used instead. There is currently a discussion about the topic on Discuss.
In order to know the GH ID to use, the migration should be completed first. blurb will either need to support both IDs for some time (possibly distinguishing them by the bpo- or gh- prefix or by some --bpo/--gh flag), or the switch from one type of ID to the other must be announced beforehand (even though this might be trickier if blurb has no way to distinguish the IDs and/or if people use an older version of blurb and/or are not aware of the switch).
