CHANGELOG.md

@@ -9,14 +9,19 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 ### Changed
 - Remove `accelerate.hpp` header that clash with Accelerate.hpp in non case sensitive OS ([#593](https://github.com/stack-of-tasks/eigenpy/pull/593)
   We don't consider it an API break since this header was rarely used.
+- Python version update ([#603](https://github.com/stack-of-tasks/eigenpy/pull/603)):
+  - Project is now tested with Python 3.10 and 3.14
+  - Python 3.10 is the minimal supported Python version
 
 ### Added
 - Support for Python slice, tuple and list indexing for `std::vector` bindings ([#592](https://github.com/stack-of-tasks/eigenpy/pull/592))
 - ROS: jrl_cmakmodules dependency + kilted CI ([#602](https://github.com/stack-of-tasks/eigenpy/pull/602))
+- Add pixi-build support ([#603](https://github.com/stack-of-tasks/eigenpy/pull/603)):
 
 ### Fixed
 - Fix partly the support of the change of API of GeneralizedEigenSolver in Eigen 5+ ([#594](https://github.com/stack-of-tasks/eigenpy/pull/594))
 - Fix Eigen decompositions and solvers for Eigen 5 ([#596](https://github.com/stack-of-tasks/eigenpy/pull/596))
+- Remove pixi 0.57 warnings ([#603](https://github.com/stack-of-tasks/eigenpy/pull/603)):
