Launchpad sunsetting Bazaar support

[Jelmer Vernooij]

Hi Doug,

We're still regularly putting out releases of Breezy (the fork of Bazaar) regularly,
and there are no plans to stop doing so.

That said, I personally use the Git format for all my new projects (even if I 
use brz with git repositories) since possible contributors are more likely to 
be able to contribute if it's in Git format.

You'll also notice that the source to Breezy itself is hosted in Git on GitHub nowadays,
even though it still supports (and there are no plans to stop that) the Bazaar format
in addition to the Git format.

Cheers,

Jelmer

As I mention below, I have over 200 private projects in it; and I am finding it daunting to migrate them all into Git, or even to start new projects in Git because I have written a lot of tools over the last 15 years or so around using bzr specifically.
