Comment 13 for bug 791076

Barry: "UbuntuBeta Mono" is the current iteration of the monospace betas and is what we've been collectively testing since UDS. Following an oversight(?), this revision hadn't landed in the natty pocket of the internal Canonical 'walled-garden' PPA. Mark pointed out that he wasn't seeing it either this out this morning, and after I eventually tracked it down I forced the copy from the beta-testing/natty PPA over the top of the Canonical walled-garden/natty PPA. This removes all of the other earlier stale/broken/experimental/alphas and the beta will be what you've got following a reboot;

The Emacs number-at-end-of-font-name is bug #697412 ("Emacs won't start, complaining about font ending in a number") and was fixed upstream in Emacs, although this may not have filtered down yet.

The size/scaling/line-counts are covered in bug #727733 ("Technical: Mono: discern level of scaling to fit in terminal cell") which IIRC you've previously participated in/subscribed to. An attachment at:

  https://bugs.launchpad.net/ubuntu-font-family/+bug/727733/+attachment/1893352/+files/ubuntu-mono-nominal-size-r17-r21.pdf

shows the relative scaling, and the line-count options that were investigated following your report. The middle option of 100/112.0 scaling was chosen, giving a 2:1 ration, good line-spacing and a reasonable line-count at a slightly differentiated x-height compared to the proportional members of the Ubuntu Font Family.

This bug: the alphas did not contain a proper bold-italic. The inclusion of UbuntuBeta Mono Bold-Italic has therefore only been available during the beta.
