51 % State of the BTS: new features, changes and tips
53 % The bug tracking system is where all bugs that affect Debian are
54 % filed. New features, including the affects, summary, and local debbugs
55 % mirror will be presented and demonstrated. Some of the underlying
56 % architectural changes to the codebase in debbugs to make it more
57 % maintainable and deployable are also outlined. Finally, a set of tips
58 % and tricks that can be used to make the BTS easier to use are
64 % - local debbugs mirror for offline work
68 % - multi-distribution/arch status
69 % - control changes at submit@ time
70 % - Code Architecture Changes
72 % - Control abstraction
73 % - release to experimental
