ZODB v3.10.2 Release Notes
Release Date: 2011-02-12 // about 13 years ago-
🐛 Bugs Fixed
- 3.10 introduced an optimization to try to address BTree conflict errors arrising for basing BTree keys on object ids. The optimization caused object ids allocated in aborted transactions to be reused. Unfortunately, this optimzation led to some rather severe failures in some applications. The symptom is a conflict error in which one of the serials mentioned is zero. This optimization has been removed.

- 🚑 ZEO server transaction timeouts weren't logged as critical.
