Somehow I can't get the latest date:

> library(AnnotationHub)
> ah <- AnnotationHub()
snapshotDate(): 2017-10-27
> query(ah, c("norvegicus", "release-92"))
AnnotationHub with 0 records
# snapshotDate(): 2017-10-27 

Is there cache data somewhere that I need to delete?

You will need to update your version of R to >= 3.5 and use the latest Bioconductor release 3.7 to see the most updated version of AnnotationHub. The snapshot date provided is the snapshot that is consistent with your version of R and the Bioconductor package version appropriate for that version/release (R 3.4.4 and Bioc release 3.6)

R 3.4 and Bioc release 3.6 uses snapshotDate(): 2017-10-27 
R 3.5 and Bioc release 3.7 uses snapshotDate(): 2018-04-30 
R 3.5 and Bioc devel 3.8 uses snapshotDate(): 2018-06-27
