|
||||
### Added
|
||||
- Add support for building for CPython limited API. This required a few minor changes to runtime behaviour of of pyo3 `#[pyclass]` types. See the migration guide for full details. [#1152](https://github.com/PyO3/pyo3/pull/1152)
|
||||
- Add feature flags `abi3-py*` to set the minimum Python version when using the limited API. [#1263]((https://github.com/PyO3/pyo3/pull/1263))
|
||||
- Add support for building for CPython limited API. Opting-in to the limited API enables a single extension wheel built with PyO3 to be installable on multiple Python versions. This required a few minor changes to runtime behaviour of of PyO3 `#[pyclass]` types. See the migration guide for full details. [#1152](https://github.com/PyO3/pyo3/pull/1152)

|
||||

### Minimum Rust version increased to Rust 1.45
|
||||
|
||||
PyO3 `0.13` makes use of new Rust language features stabilised between Rust 1.40 and Rust 1.45. If you are using a Rust compiler older than Rust 1.45, you will need to update your toolchain to be able to continue using PyO3.
|
||||
|
||||
### Runtime changes to support the CPython limited API
|
||||
|
||||
In PyO3 `0.13` support was added for compiling against the CPython limited API. This had a number of implications for _all_ PyO3 users, described here.
