There seems to still be a number of regressions being found, as well as TLS/Security updates and/or fixes for new found vulnerabilities that are rolling into 9.0.1 FP5 & FP6, that aren't listed in 9.0.2 fix list.
So, it 'seems' like, if 9.0.2 were to be released today, that there might be fixes made to 9.0.1FP6 that weren't included in 9.0.2.
Unless you're saying that all the 9.0.1FP6 fixes that are being 'announced' are all already included in the base 9.0.2 code, in which case my mind rests easier!
Thanks!
