+  * CI doc build fixes (#322) and added the ability to skip executing
+    notebooks when building docs (#319)
+
+  * fixed issues with how derived variables are recognized when
+    reading in an output file and add vorticity and machnumber

+
+  * spherical compressible solver fixes (#295, #296, #298, #299, #300)
+
+  * move the 4th order reconstruction into mesh (#302)
+
+  * use a safer divide in compressible when density is zero (#297)

+  * add the ability to have a problem-dependent external source and
+    clean-up how the compressible sources are treated (#289, #290,
+    #292)
+
 # 4.4.0
 
   * the gresho problem (compressible) now takes Mach number as input
