I have read, implemented, and deployed the changes in HPKE since -07.
I do want to confirm however that the change in test vectors between -08 (where the final version string was added) and -09 was just the result of missing the test vectors in the -08 update. I've code that uses the source JSON file, which were updated one day after -08 was published.
Nit: in \S9.7.5, the first sentence could use an em-dash (' - ' or ' -- ' to taste):
If the randomness used for KEM encapsulation is bad - i.e., of low
entropy or compromised because of a broken or subverted random number
generator - the confidentiality guarantees of HPKE degrade
significantly.
