+QuTiP 5.1.0 (2024-12-12)
+========================
+
+Features
+--------
+
+- It adds odd parity support to HEOM's fermionic solver (#2261)
+- Create `SMESolver.run_from_experiment`, which allows to run stochastic evolution from know noise or measurements. (#2318)
+- Add types hints. (#2327, #2473)
+- Weighted trajectories in trajectory solvers (enables improved sampling for nm_mcsolve) (#2369)
+- Updated `qutip.core.metrics.dnorm` to have an efficient speedup when finding the difference of two unitaries. We use a result on page 18 of
+  D. Aharonov, A. Kitaev, and N. Nisan, (1998). (#2416)
+- Allow mixed initial conditions for mcsolve and nm_mcsolve. (#2437)
+- Add support for `jit` and `grad` in qutip.core.metrics (#2461)
+- Allow merging results from stochastic solvers. (#2474)
+- Support measurement statistics for `jax` and `jaxdia` dtypes (#2493)
+- Enable mcsolve with jax.grad using numpy_backend (#2499)
+- Add propagator method to steadystate (#2508)
+- Introduces the qutip.core.environment module, which contains classes that characterize bosonic and fermionic thermal environments. (#2534)
+- Implements a `einsum` function for Qobj dimensions (Evaluates the Einstein summation convention on the operands.) (#2545)
+- Wave function calculations have been sped up with a Cython implementation.
+  It optimizes the update method of the HarmonicOscillatorWaveFunction class in distribution.py. (#2553)
+- Speed up `kraus_to_super` by adding a `sparse` option. (#2569)
+
+
+Bug Fixes
+---------
+
+- Fix a dimension problem for the argument color of Bloch.add_states
+  Clean-up of the code in  Bloch.add_state
+  Add Bloch.add_arc and Bloch.add_line in the guide on Bloch class (#2445)
+- Fix HTMLProgressBar display (#2475)
+- Make expm, cosm, sinm work with jax. (#2484)
+- Fix stochastic solver step method (#2491)
+- `clip` gives deprecation warning, that might be a problem in the future. Hence switch to `where` (#2507)
+- Fix brmesolve detection of contant vs time-dependent system. (#2530)
+- `propagator` now accepts list format `c_ops` like `mesolve` does. (#2532)
+- Fix compatibility issue with matplotlib>=3.9 in matrix_histogram (#2544)
+- Resolve incompatibility of TwoModeQuadratureCorrelation class (#2548)
+
+
+Documentation
+-------------
+
+- Improve guide-settings page. (#2403)
+- Tidy up formatting of type aliases in the api documentation (#2436)
+- Update documentation
+  - Update contributors
+  - Improve apidoc readability (#2523)
+
+
+Miscellaneous
+-------------
+
+- Add auto_real_casting options. (#2329)
+- Add dispatcher for sqrtm (#2453)
+- Make `e_ops`, `args` and `options` keyword only.
+  Solver were inconsistent with `e_ops` usually following `c_ops` but sometime
+  preceding it. Setting it as keyword only remove the need to memorize the
+  signature of each solver. (#2489)
+- Introduces a new `NumpyBackend `class that enables dynamic selection of the numpy_backend used in `qutip`.
+  The class facilitates switching between different numpy implementations ( `numpy` and `jax.numpy` mainly ) based on the configuration specified in `settings.core`. (#2490)
+- Improve mkl lookup function. (#2497)
+- Deterministic trajectories are not counted in ``ntraj``. (#2502)
+- Allow tests to be executed multiple times in one Python session (#2538)
+- Improve performance of qutip.Qobj by using static numpy version check (#2557)
+- Fix towncrier check (#2542)
