I've just made a new beta release of ZODB 3.8.1,
This has 3 bug fixes:
- Fixed a bug, introduced in an earlier beta, that allowed
clients to connect to out of date servers.
- Fixed bug that could lead to memory errors due to the use
of a Python dictionary for a mapping that can grow large.
- Fixed bug #251037: Made packing of blob storages non-blocking.
