+[Github Commits](https://github.com/PlasmaControl/DESC/compare/v0.10.3...v0.10.4)
+
 - `Equilibrium.map_coordinates` is now differentiable.
 - Removes method `Equilibrium.compute_flux_coordinates` as it is now redundant with the
 more general `Equilibrium.map_coordinates`.
 - Allows certain objectives to target ``FourierRZToroidalSurface`` objects as well as
-``Equilibrium`` objects, such as ``MeanCurvature``, ``MeanCurvature``, and ``Volume``.
+``Equilibrium`` objects, such as ``MeanCurvature``, ``PrincipalCurvature``, and ``Volume``.
 - Allow optimizations where the only object being optimized is not an ``Equilibrium``
 object e.g. optimizing only a ``FourierRZToroidalSurface`` object to have a certain
 ``Volume``.
 - Many functions from ``desc.plotting`` now also work for plotting quantities from
 ``Curve`` and ``Surface`` classes.
-- Adds method ``constant_offset_surface`` to ``FourierRZToroidalSurface`` which creates a  surface with a specified constant offset from the base surface.
+- Adds method ``FourierRZToroidalSurface.constant_offset_surface`` which creates
+a  surface with a specified constant offset from the base surface.
+- Adds method ``FourierRZToroidalSurface.from_values``  to create a surface by fitting
+(R,phi,Z) points, along with a user-defined poloidal angle theta which sets the poloidal
+angle for the created surface
+- Adds new objective ``LinearObjectiveFromUser`` for custom linear constraints.
+- `elongation` is now computed as a function of zeta rather than a single global scalar.
+- Adds `beta_vol` and `betaxis` to VMEC output.
+- Reorder steps in `solve_continuation_automatic` to avoid finite pressure tokamak with
+zero current.
+- Fix error in lambda o(rho) constraint for near axis behavior.
+- Fix bug when optimizing with only a single constraint.
+- Fix some bugs causing NaN in reverse mode AD for some objectives.
+- Fix incompatible array shapes when user supplies initial guess for lagrange multipliers
+for augmented lagrangian optimizers.
+- Fix a bug caused when optimizing multiple objects at the same time and the order of
+the objects gets mixed up.
