  -----------------
  
 -- Issue #26154: Add a new private _PyThreadState_UncheckedGet() function to get
 -  the current Python thread state, but don't issue a fatal error if it is NULL.
 -  This new function must be used instead of accessing directly the
 -  _PyThreadState_Current variable.  The variable is no more exposed since
 -  Python 3.5.1 to hide the exact implementation of atomic C types, to avoid
 -  compiler issues.
+ - Issue #4806: Avoid masking the original TypeError exception when using star
+   (*) unpacking in function calls.  Based on patch by Hagen Fürstenau and
+   Daniel Urban.
+ 
 +- Issue #26146: Add a new kind of AST node: ``ast.Constant``. It can be used
 +  by external AST optimizers, but the compiler does not emit directly such
 +  node.
  
 -- Issue #26194:  Deque.insert() gave odd results for bounded deques that had
 -  reached their maximum size.  Now, the insert will happen normally and then
 -  any overflowing element will be truncated from the right side.
 +- Issue #18018: Import raises ImportError instead of SystemError if a relative
 +  import is attempted without a known parent package.
  
  - Issue #25843: When compiling code, don't merge constants if they are equal
    but have a different types. For example, ``f1, f2 = lambda: 1, lambda: 1.0``
