Canonical created a dedicated Unity fixing-issues-only maintenance team (starting with Ubuntu 13.04)

Across the latest cycles, Ubuntu has been subjected to a serious quality-focused effort, internal energy aimed at (and successfully implemented) constantly strengthening, optimizing and enhancing the full-fledged OS.

Nevertheless, it seems that the mentioned quality work has touched only certain Ubuntu parts, consequently, generating more quality for specific desktop parts (effort translated into an overall improved Ubuntu).

October 2012 saw the happening of Ubuntu Developer Summit, event where, along with numerous and numerous ideas, plans, targets, etc, the developers decided to form and dedicate a team of developers rooted in the singular purpose of maintaining and enhancing Unity.

The only-Unity team's work is to be observed starting with Ubuntu 13.04, "for the first time we have a full team dedicated exclusively to the goal of fixing problems in the existing Unity desktop shell software".

A definitely exciting aspect of the mentioned team is its attitude, meaning, the team is focused only on fixing (and improving, etc) Unity, not on adding new features (latter aspect further pursued and developed by the same-until-now developers), "We’re not working on adding new features. We’re making what’s there work and work better".

The developers are "looking forward to a smooth, better-than-ever Ubuntu desktop in 13.04".
