+1.0.18.0
+    Added: Orbital readouts - "Speed at Periapsis" and "Speed at Apoapsis". (Padishar)
+    Added: Manoeuvre readouts - "Post-burn Apoapsis" and "Post-burn Periapsis". (Padishar)
+    Fixed: Synched the minimum simulation time sliders and stopped them from snapping back after 999ms. (saybur)
+    Fixed: Added workaround for the bug in Vessel.horizontalSrfSpeed (Padishar)
+    Fixed: Physically insignificant part mass was not being correctly cascaded down through multiple parent parts.
+
 1.0.17.0
     Added: 'Mach Number' readout under the 'Surface' category and included it on the default surface HUD.
+    Added: Stock sections in the Flight Engineer can now become HUDs.
     Added 'Thermal' readouts category including:
         Internal Flux
         Convection Flux
         Radiation Flux
         Critical Part Name
         Critical Part Temperature

     Changed: Mach on the Build Engineer now accurate to 2 decimal places.
     Changed: Max mach in the Build Engineer defaults to 1.00 even when no jet engines are present.
-    Changed: Increased eccentricity readout to 5 decimal places.  
-    Changed: Implemented Sarbian's object pooling. 
-    Changed: How the default selected body is assigned to 'Planitarium.Home'.
+    Changed: Increased eccentricity readout to 5 decimal places.
+    Changed: Implemented Sarbian's object pooling.
+    Changed: The default selected body is now assigned via 'Planitarium.Home'.
     Changed: HUDs to clamp fully inside the screen instead of allowing them to run off the edge by a certain amount.
     Fixed: Physically insignificant part mass is now associated with the parent part.
     Fixed: Longitude and Latitude readouts now use a KER formatter instead of Squad's incorrect implementation.
