Release engineering for 3.5.4rc1 and 3.4.7rc1 took a lot longer than
expected, because this is the first release using "blurb", and it
turned out there was a lot of work left to do and a couple dark
corners yet to stumble over. 3.5.4rc1 and 3.4.7rc1 will be released
Monday, July 24, 2017. The release dates for 3.5.4 final and 3.4.7
final are not expected to change.
Sorry about that,
