See http://www.zodb.org/zodbbook/transactions.html for narrative documentation on its usage.
Changes
1.2.0 (2011-12-05)
New Features:
Python 3.2 compatibility.
Dropped Python 2.4 and 2.5 compatibility (use 1.1.1 if you need to use “transaction” under these Python versions).
1.1.1 (2010-09-16)
Bug Fixes:
Code in _transaction.py held on to local references to traceback objects after calling sys.exc_info() to get one, causing potential reference leakages.
Fixed hexlify NameError in transaction._transaction.oid_repr and add test.
1.1.0 (1010-05-12)
New Features:
Transaction managers and the transaction module can be used with the with statement to define transaction boundaries, as in:
with transaction: ... do some things ...See transaction/tests/convenience.txt for more details.
There is a new iterator function that automates dealing with transient errors (such as ZODB confict errors). For example, in:
for attempt in transaction.attempts(5): with attempt: ... do some things ..If the work being done raises transient errors, the transaction will be retried up to 5 times.
See transaction/tests/convenience.txt for more details.
Bugs fixed:
Fixed a bug that caused extra commit calls to be made on data managers under certain special circumstances.

When threads were reused, transaction data could leak accross them, causing subtle application bugs.
1.0.1 (2010-05-07)
LP #142464: remove double newline between log entries: it makes doing smarter formatting harder.
Updated tests to remove use of deprecated zope.testing.doctest.
1.0.0 (2009-07-24)
Fix test that incorrectly relied on the order of a list that was generated from a dict.
Remove crufty DEPENDENCIES.cfg left over from zpkg.
1.0a1 (2007-12-18)
- = Initial release, branched from ZODB trunk on 2007-11-08 (aka
“3.9.0dev”).
Remove (deprecated) support for beforeCommitHook alias to addBeforeCommitHook.
Add weakset tests.
Remove unit tests that depend on ZODB.tests.utils from test_transaction (these are actually integration tests).
