Dear EM community,

We are pleased to announce another release of Scipion, v1.2.1 is now

   - Protocols can now wait for other protocols to finish before starting
   (internal scheduling)
   - Allow some protocols to "wait" and work in "batch" mode to reduce the
   IO operations in fast protocols (while checking for updates in the stream).
   - Schedule batch of 2D classification jobs one after each other

We are also very happy to see the Scipion development becoming more
distributed. The main developers team is in Madrid, but now core developers
are also in Stockholm, Montreal and Cambridge. We will be really happy to
have more people on-board, come and join us!

For the next release, we are going for a more strong “pluginization”, to
make the whole platform more easy to maintain and the development more
agile. Stay tuned and keep an eye!
