Samba 4.9.0rc2 lmdb question.

[L.P.H. van Belle]

Hai i have a few small questions about the LMDB version. 

I want to make test package for debian with 4.9.rc2 with LMDB.
I notice in the debian tree, 0.9.22

I saw in the changelogs these 2. 
lmdb (0.94)  0.9.22
* Removed Python 2.6 support due to urllib3 warnings and pytest dropping it.

lmdb (0.93)  ? 
* py-lmdb currently does not support LMDB >=0.9.19 due to interface changes in
  LMDB

So my question is, is it safe to start with 0.9.22 or is it better to start with 0.9.18-5 ( from debian stretch/stable )
