The new IMSLP dump that I've started on 6 January just finished few hours ago.
The XML dumping piece finished on 27 February.
The bad news:
* I got a corrupted XML dump:
$ grep "<title>" *.xml -c;grep "<page>" *.xml -c;grep "</page>" *.xml -c;grep "<revision>" *.xml -c;grep "</revision>" *.xml -c
463544
463544
463526
1418977
1418976
* I cannot run a new dump. In fact, I was only waiting for this dump finishes to take a new wikibreak on wikiteam tasks (busy both on Wikimedia and on real life; dumping IMSLP isn't only a resource consumer thing, but also needs lots of babysitting).
By the way, I'm 7zipping the generated files to upload into Internet Archive, since those includes 90% of valid XML revisions and 319925 media files.
