+# CHANGELOG
+
+All notable changes to `dae-cpp` project will be documented in this file.
+
+## [`develop` branch -- 2.3.0]
+
+### Added
+
+- Option `linear_system_scaling` (can be `true` or `false`) to rescale linear system matrix for better convergence (`false` by default).
+- Linear system matrix (row) scaling. Matrix scaling can improve stability of the linear solver in some cases but comes with a slight performance penalty.
+- Linear system matrix prune if scaling is enabled.
+
+### Fixed
+
+- The solver cannot reach relative tolerance `rtol` in some cases and stops with the "solution diverged" error (fixed by updating internal tolerances).
+- Incompatibility of `autodiff` library with the latest version of Eigen (fixed by altering `autodiff`).
+- Typo in `daecpp::solver_command::stop_integration` enum (`stop_intergration` -> `stop_integration`).
+
+### Changed
+
+- Eigen to version 5.0.0.
+- Renamed `TESTING` macro definition to `DAECPP_TESTING` to avoid potential clash.
+- Linear system matrix pattern now analysed only once at the first iteration.
+- Pre-allocate vector of `dual` numbers in `JacobianMatrixShape` class to improve performance of the Jacobian computed from the user-defined shape.
+- Updated internal tolerances used in the solver for the convergence check against relative tolerance `rtol`.
+
+### Removed
+
+- Conversion from Eigen to dae-cpp matrix format and back in automatic Jacobian class (an attempt to speed it up).
+
+## [2.2.0]
+
+Current stable version.
