 # 23.11
 
+  * Problem GNUmakefiles have been standardized and now allow for the
+    problem to be compiled elsewhere (#2640, #2641, #2642, #2643)
+
+  * The true-SDC Newton solver has been made more robust and faster
+    (#2586, #2602, #2605, #2606)
+
+  * Several problems that required the initial model grid spacing to
+    be specified in the inputs file now automatically compute it as
+    needed, including `flame_wave` (#2610), `convective_flame`,
+    `bubble_convergence`, and `hse_convergence` (#2624), `double_bubble`,
+    `gamma_law_bubble`, and `hse_convergence_general` (#2612)
+
+  * Outflow boundary conditions for the 4th order solver have been changed
+    to no longer use the one-sided stencil (#2607)
+
   * The ca_rad_source hook in Fortran has been removed. The existing
     problem_rad_source() hook in C++ can be used instead. (#2626)

     manually update the auxiliary parameters, you can use an external
     source term or you can use the problem post-timestep hook. (#2614)
 
+  * The pressure is now always included in the x-momentum flux in 1-d
+    Cartesian, and this fixes an issue at jumps in refinement with the
+    pressure gradient (#2468)
+
+  * A bug was fixed in the 4th order diffusion operator that was introduced
+    when it was originally converted to C++ (#2592)
+
+  * The 2nd order Radau integrator had the wrong quadrature weights
+    (#2594)
+
 # 23.10
 
   * True-SDC no longer evolves density as part of the reaction system
