Dear all,

I have the following code that once worked:

Loading required package: parallel 
...

Error in FUN(genome = names(SUPPORTED_UCSC_GENOMES)[idx], circ_seqs = supported_genome$circ_seqs,  :

Note that my GenomeInfoDb is not the most updated version, but it is the last available for bioc 3.8/R 3.5 which I have to stick to for a while.

I suspect it might be caused by some recent update of the UCSC database... Does anybody know? Thanks.

No, this was fixed in release as well. Just not all releases. Only the current one.

We don't support old releases, so if you are stuck using Bioc3.8, you'll likely have to get the sources and then emulate the changes that Herve made. Assuming of course that there aren't other breaking changes.
