-## [unreleased][]
+## [Unreleased][]
+
+### Added
+
+### Changed
+-   Drop support for Python 2
+
+### Fixed
+
+-    Fix incorrect dereference of wrapper object in `tp_repr`, which may result in a program crash
+-    Fix incorrect dereference in params array handling
+
+## [2.5.0][] - 2020-06-14
+
+This version improves performance on benchmarks significantly compared to 2.3.
+
+### Added
+
+-   Automatic NuGet package generation in appveyor and local builds
+-   Function that sets `Py_NoSiteFlag` to 1.
+-   Support for Jetson Nano.
+-   Support for `__len__` for .NET classes that implement ICollection
+-   `PyExport` attribute to hide .NET types from Python
+-   `PythonException.Format` method to format exceptions the same as
+    `traceback.format_exception`
+-   `Runtime.None` to be able to pass `None` as parameter into Python from .NET
+-   `PyObject.IsNone()` to check if a Python object is None in .NET.
+-   Support for Python 3.8
+-   Codecs as the designated way to handle automatic conversions between
+    .NET and Python types
+
+### Changed
+
+-   Added argument types information to "No method matches given arguments" message
+-   Moved wheel import in setup.py inside of a try/except to prevent pip collection failures
+-   Removes `PyLong_GetMax` and `PyClass_New` when targetting Python3
+-   Improved performance of calls from Python to C#
+-   Added support for converting python iterators to C# arrays
+-   Changed usage of the obsolete function
+    `GetDelegateForFunctionPointer(IntPtr, Type)` to
+    `GetDelegateForFunctionPointer<TDelegate>(IntPtr)`
+-   When calling C# from Python, enable passing argument of any type to a
+    parameter of C# type `object` by wrapping it into `PyObject` instance.
+    ([#881][i881])
+-   Added support for kwarg parameters when calling .NET methods from Python
+-   Changed method for finding MSBuild using vswhere
+-   Reworked `Finalizer`. Now objects drop into its queue upon finalization,
+    which is periodically drained when new objects are created.
+-   Marked `Runtime.OperatingSystemName` and `Runtime.MachineName` as
+    `Obsolete`, should never have been `public` in the first place. They also
+    don't necessarily return a result that matches the `platform` module's.
+-   Unconditionally depend on `pycparser` for the interop module generation
+
+### Fixed
+
+-   Fixed runtime that fails loading when using pythonnet in an environment
+    together with Nuitka
+-   Fixes bug where delegates get casts (dotnetcore)
+-   Determine size of interpreter longs at runtime
+-   Handling exceptions ocurred in ModuleObject's getattribute
+-   Fill `__classcell__` correctly for Python subclasses of .NET types
+-   Fixed issue with params methods that are not passed an array.
+-   Use UTF8 to encode strings passed to `PyRun_String` on Python 3

 ### Changed
 
+-   PythonException included C# call stack
 -   Reattach python exception traceback information (#545)
 -   PythonEngine.Intialize will now call `Py_InitializeEx` with a default value of 0, so signals will not be configured by default on embedding. This is different from the previous behaviour, where `Py_Initialize` was called instead, which sets initSigs to 1. ([#449][i449])
+-   Refactored MethodBinder.Bind in preparation to make it extensible (#829)
