Add getter methods to all fields, not just where needed

docs/CHANGELOG.md

 ### New features:
 
+- genqlient now generates getter methods for all fields, even those which do not implement a genqlient-generated interface; this can be useful for callers who wish to define their own interface and have several unrelated genqlient types which have the same fields implement it.
+
 ### Bug fixes:
 
+- In certain very rare cases involving duplicate fields in fragment spreads, genqlient would generate code that failed to compile due to duplicate methods not getting promoted; genqlient now generates correct types.  (See #126 for a more complete description.)
+
 ## v0.3.0
 
 Version 0.3.0 adds several new configuration options, allowing simplification of generated types and configuration of input types, as well as marshalers for all genqlient-generated types.
