The reason for this is that I had a project based on SVN 1.4 which stored HEAD revisions of XML files in Berkeley DB XML - a native XML database-, instead of BDB. (reverted deltas as well as "normal" files kept on living in BDB). In this way I could also query HEAD XML files directly from SVN repository and access them via BDB XML API - thus it was a nice combination of SVN and XML-database. Recently I've ported my project to SVN 1.7 and due to forward deltas it didn't work as before -- only old revisions of XML files were in BDB XML. But now I changed SVN_FS_BASE__MIN_FORWARD_DELTAS_FORMAT to a higher number, and my project works again as expected. Vyacheslav
