I've started simplewallet together with bitmonerod and looking into simplewallet.log file I can see something like this:
2016-Sep-08 12:01:29.853608 [RPC0]Transaction extra has unsupported format: <c24dcecfe0ad013293600321caf59e22582f87c180264d592a02bb2d5edb7b42>

There is more entries like this in log file. Can someone explain what does it mean?
I'm running 'Hydrogen Helix' (v0.9.4.0-release) in screen.
