 ### Common
   - Bug: Found a bug in book 3 source `isotropic::scatter()` method. Commented out, using default
     (as it was previously). (#669)
-  - Removed: now that the code handles ray-surface intersection from either side, we no longer need
-    the `flip_face` class, so we've deleted it from the text and from the code (#482, #270)
+  - Delete: vestigial `vec3::write_color()` method (now in color.h)
+  - Change: All images and figures renamed to follow more logical convention, using the following
+    pattern: `{fig,img}-<book>.<sequence>-<title>.<filetype>` (#495)
+  - Change: `main()` function gets organized into image, world, camera, and render chunks
   - Change: Added header guards to the text of all three books whenever a new header file was
-    introduced
+    introduced, consistent with source code (#645)
+  - New: Added constructors that take `color` arguments in addition to the constructors
+    taking `shared_ptr<texture>` arguments, simplifying calling code. Applies to `checker_texture`,
+    `constant_medium`, `diffuse_light`, `lambertian`, and `isotropic` (#516, #644)
   - Change: Added `override` keywords throughout. This keyword marks a subclass method as one that
     is intended to override a superclass method. It makes the code a bit easier to understand, and
     ensures that your function is actually overriding the method you think it is. Which is good,

 ### _The Next Week_
-  - Removed: Deleted the section covering the old `flip_face` class, renumbered images as this
-    eliminated the rendering with missing Cornell box faces (#482, #661)
-  - Change: Renamed and explicitly numbered book images and figures (#495)
-  - Fix: Reduced code duplication in dielectric::scatter() function
-  - New: Added alternative constructors that take color arguments in addition to the constructors
