ZODB v5.2.0 Release Notes

Release Date: 2017-02-09 // almost 6 years ago
    • 🆓 Call new afterCompletion API on storages to allow them to free resources after transaction complete. See issue 147 <https://github.com/zodb/relstorage/issues/147>__.
    • Take advantage of the new transaction-manager explicit mode to avoid starting transactions unnecessarily when transactions end.

    • Connection.new_oid delegates to its storage, not the DB. This is helpful for improving concurrency in MVCC storages like RelStorage. See issue 139 <https://github.com/zopefoundation/ZODB/issues/139>_.

    • persistent is no longer required at setup time. See issue 119 <https://github.com/zopefoundation/ZODB/issues/119>_.

    • Connection.close and Connection.open no longer race on self.transaction_manager, which could lead to AttributeError. This was a bug introduced in 5.0.1. See issue 142 <https://github.com/zopefoundation/ZODB/pull/143>_.
