Hallöchen! Lensfun just released a version 0.3.2. Changes in the build system are intended to make Debian packaging easy.
Moreover, not only the library file is properly versioned (liblensfun.so.x), the same is now implemented for the database itself. Multiple database version can live happily together on the same filesystem. This is necessary because every binary library depends on a particular file format of the database, and this file format may change over time, independently of the ABI version. We suggest to count the database format version in the Debian package name as it is common for libraries: lensfun-data1, lensfun-data2, etc. Regards, Torsten Bronger. -- Torsten Bronger Jabber ID: torsten.bron...@jabber.rwth-aachen.de
