 ## Changes affecting backwards compatibility
 
-- All `strutils.rfind` procs now take `start` and `last` like `strutils.find`
-  with the same data slice/index meaning. This is backwards compatible for
-  calls *not* changing the `rfind` `start` parameter from its default. (#11487)
-
-  In the unlikely case that you were using `rfind X, start=N`, or `rfind X, N`,
-  then you need to change that to `rfind X, last=N` or `rfind X, 0, N`. (This
-  should minimize gotchas porting code from other languages like Python or C++.)
-
-- On Windows stderr/stdout/stdin are not opened as binary files anymore. Use the switch
-  `-d:nimBinaryStdFiles` for a transition period.
 
 ### Breaking changes in the standard library
 
-- Mac OS X / BSD: TSa_Family is now the ``uint8`` type, so type
-  conversions like ``x.sin_family = uint16 toInt(nativesockets.AF_INET)``
-  need to be changed into ``x.sin_family = TSa_Family toInt(nativesockets.AF_INET)``.
