Please find attached the latest patch set v69*
Differences from v68* are:
* Rebased to HEAD @ yesterday.
There was some impacts caused by recently pushed patches [1] [2]
* The stream/prepare functionality and tests have been restored to be
the same as they were in v48 [3].
Previously, this code had been removed back in v49 [4] due to
incompatibilities with the (now obsolete) psf design.
* TAP tests are now co-located in the same patch as the code they are testing.
