Release Notes for ELKI 0.4

Release 0.4 marks another big milestone in ELKI development, but also highlights why we still do not use a 1.x version number: things still change at a large scale, so expect to be code that was written for ELKI 0.3 to require a lot of work to work with 0.4. The scope of ELKI is still widening, and many of the APIs need to grow with these requirements. For example to support specialized spatial algorithm, the database layer now needs to have solid support for multi-relational operation. In order to have the database layer fully exploit index structures, the query API needs to support features that you might know from traditional databases: optimizer hints and “prepared queries”.
