-** v0.1.6 - 2025-12-02
-
-+ Treat empty hash as nil
-
-  Tom: I think that if go's behaviour is to insert an empty map when nil is
-  returned as a templatenest.Hash, then we need to change the templatenest
-  behaviour to regard an empty map as being nil.
-
-** v0.1.5 - 2025-02-22
-
-+ Handle all pointer types generically.
-
-** v0.1.4 - 2025-01-09
-
-+ Fix nil pointer dereference error.
-
-** v0.1.3 - 2024-11-24
-
-+ Fix handling of numeric types.
-
-  Earlier numeric values would result in an error (value type not supported),
-  this was due to a programming error. I've fixed the error and added support
-  for more numeric types.
-
 ** v0.1.0 - 2024-11-18
 
 + Initial Release.
