Since we are planning to add more refactoring in the internal (variables vs. attributes) representation of ADIOS2, let's not make this default over ADIOS1 yet to avoid writing files that soon cannot be read again.

Delay this just for a little for this upcoming release, so we can draft a new version without changing defaults yet. (I want to release a new version very soon to fix some installation issues and other updates that we accumulated.)

Delays the new defaults to ADIOS2 in #568 for a later release.

ping @franzpoeschel is this fine with you, too?

Just want to push a bug-fix release and the ADIOS2 files we write will probably change with your further updates for read speed, I guess?

@ax3l This is ok as long as the ADIOS2 backend hasn't stabilized yet. I have already implemented the necessary changes on topic-streaming and will backport them to dev soon. Those changes do not affect the layout of the BP4 file, since the implementation does not add ADIOS variables for groups, unlike initially planned. (see here)

Okay, thanks for the heads-up on this. I wasn't sure anymore.
