Python Transaction Management

The `transaction` package provides a generic transaction implementation for Python, offering a two-phase commit protocol. It allows multiple backends (such as ZODB, SQLAlchemy, filesystem, or custom data managers) to participate in a single transaction, ensuring atomicity across diverse storage systems. It also supports savepoints, enabling partial rollbacks. The current version is 5.1, with a release cadence that has seen several major updates over the last few years, maintaining active development.
