v0.12 of fastqc from last year changed the default adapters it searches and now no longer reports SOLID adapters, but polyA and polyG instead.
see: https://github.com/s-andrews/FastQC/releases/tag/v0.12.0
The new release also now reports the total base count in basic stats, which would be good to have reflected in falco I guess.
Other changes in the fastqc release look less important at first glance (though maybe the deduplicated sequences line still present in falco will confuse people even more now that it got removed from fastqc).
