Subject: ROOT I/O workshop notable 
The ROOT I/O workshop was held on June 20th at CERN. A few things of interest in MIDAS land:

- LZ4 is now used as default compression (replacing gzip-1)
- JSON class streamer is finally implemented (XML streamer updated/reworked)
- recursive read-write lock class implemented
- do not see any special mention of Javascript I/O or jsroot, but jsroot git repo seems to be quite active

Of these the recursive read-write lock is most interesting - using something similar would improve ODB performance
and presumably fix the existing lock fairness problems.
