Why was 17.6 pulled from MOS
We have downloaded 17.6 and are using it and notice that now it is no longer on My Oracle Support. We are wondering why this patch set was pulled and if perhaps it has a serious bug that we have not found yet.
Last year 16.13, .14, and .15 were pulled off the market (I think these are the versions - anyway there were 3 of them in this range) due to a serious bug with non Unicode 1252 Oracle databases. 17 has three bugs related to 1252 and .6 has the last new one. I don't think this is the reason why 17.6 was pulled since for 17 you either have to work around these bugs or convert to UTF-8.
