 ### Small ring angles
 The following changes were made to the small ring angles:
 
-* `a3 [*;r3:1]1~;@[*;r3:2]~;@[*;r3:3]1` moved to the end of the angle list, in order to supersede parameter `a28` which was being used for epoxy internal angles prior to Sage 2.2. `a28`'s equilibrium angle value is around 112 degrees, while the epoxy internal angle should be around 60 degrees.

 ### Heteroatomic 3-membered ring improvements
 
-Treating the C-O-C epoxy internal angle with `a28` in Sage 2.1.0 led to a distorted geometry that has been remedied in Sage 2.2.0. The plot below shows the internal coordinate RMS error for molecules with heteroatomic 3-membered rings, and an example geometry with the problematic bonds and angles listed.
