 Fixes
 -----
 
-- USD::PrimitiveAlgo :
+- IECoreUSD::PrimitiveAlgo (#1346) :
   - Fixed reading of primitives containing `primvars:normals`. These are now correctly loaded as a primitive variable called `N`, taking precedence over the UsdGeomPointBased `normals` attribute.
   - Fixed writing of indexed normals so that the indexing is retained on load. Note that this means that normals are now _always_ written as `primvars:normals` and never via the UsdGeomPointBased `normals` attribute.
