-## [Unreleased]
+## [0.13.1] - 2021-01-10
 ### Added
 - Add support for `#[pyclass(dict)]` and `#[pyclass(weakref)]` with the `abi3` feature on Python 3.9 and up. [#1342](https://github.com/PyO3/pyo3/pull/1342)
 - Add FFI definitions `PyOS_BeforeFork`, `PyOS_AfterFork_Parent`, `PyOS_AfterFork_Child` for Python 3.7 and up. [#1348](https://github.com/PyO3/pyo3/pull/1348)
-- Add `auto-initialize` feature to control whether PyO3 should automatically initialize an embedded Python interpreter. For compatibility this feature is enabled by default in PyO3 0.13.1, but is planned to become opt-in from PyO3 0.14.0. [#1347](https://github.com/PyO3/pyo3/pull/1347)

 - Deprecate FFI definitions `PyGetSetDef_DICT` and `PyGetSetDef_INIT` which have never been in the Python API. [#1341](https://github.com/PyO3/pyo3/pull/1341)
 - Deprecate FFI definitions `PyGen_NeedsFinalizing`, `PyImport_Cleanup` (removed in 3.9), and `PyOS_InitInterrupts` (3.10). [#1348](https://github.com/PyO3/pyo3/pull/1348)
 - Deprecate FFI definition `PyOS_AfterFork` for Python 3.7 and up. [#1348](https://github.com/PyO3/pyo3/pull/1348)
-- Deprecate FFI definition `PyCoro_Check` and `PyAsyncGen_Check` in favor of `PyCoro_CheckExact` and `PyAsyncGen_CheckExact` respectively to mirror Python API. [#1348](https://github.com/PyO3/pyo3/pull/1348)
-- Deprecate FFI definition `PyCoroWrapper_Check` which has never been in the Python API. [#1348](https://github.com/PyO3/pyo3/pull/1348)
+- Deprecate FFI definitions `PyCoro_Check`, `PyAsyncGen_Check`, and `PyCoroWrapper_Check`, which have never been in the Python API (for the first two, it is possible to use `PyCoro_CheckExact` and `PyAsyncGen_CheckExact` instead; these are the actual functions provided by the Python API). [#1348](https://github.com/PyO3/pyo3/pull/1348)
 - Deprecate FFI definitions for `PyUnicode_FromUnicode`, `PyUnicode_AsUnicode` and `PyUnicode_AsUnicodeAndSize`, which will be removed from 3.12 and up due to [PEP 613](https://www.python.org/dev/peps/pep-0623/). [#1370](https://github.com/PyO3/pyo3/pull/1370)
 
 ### Removed
 - Remove FFI definition `PyFrame_ClearFreeList` when building for Python 3.9. [#1341](https://github.com/PyO3/pyo3/pull/1341)
 - Remove FFI definition `_PyDict_Contains` when building for Python 3.10. [#1341](https://github.com/PyO3/pyo3/pull/1341)
-- Remove FFI definitions `PyGen_NeedsFinalizing`, `PyImport_Cleanup` (for 3.9 and up), and `PyOS_InitInterrupts` (3.10). [#1348](https://github.com/PyO3/pyo3/pull/1348)
