Logilab will be present at the upcoming Debian BSP in Paris this week-end. This event will focus on fixing as many "release critical" bugs as possible, to help with the preparation of the upcoming Debian 7.0 "wheezy" release. It will also provide an opportunity to introduce newcomers to the processes of Debian development and bug fixing, as well as provide an opportunity for contributors in various areas of the project to interact "in real life".
The current stable release, Debian 6.0 "squeeze", came out in February 2011. The development of "wheezy" is scheduled to freeze in June 2012, for an eventual release later this year.
Among the things we hope to work on during this BSP, the latest HDF5 release (1.8.8) includes API and packaging changes that require some changes in dependent packages. With the number of scientific packages relying on HDF5, this is a pretty big change, as tracked in this Debian bug.
