 ========================
-Announcing NumExpr 2.8.5
+Announcing NumExpr 2.8.6
 ========================
 
 Hi everyone, 
 
-In 2.8.5 we have added a new function, `validate` which checks an expression `ex`
-for validity, for usage where the program is parsing a user input. There are also 
-consequences for this sort of usage, since `eval(ex)` is called, and as such we 
-do some string sanitization as described below.
+NumExpr 2.8.6 is a release to deal with issues related to downstream `pandas`
+where the sanitization blacklist was hitting private variables used in their
+evaluate. In addition the sanitization was hitting on scientific notation.
+
+For those who do not wish to have sanitization on by default, it can be changed 
+by setting an environment variable, `NUMEXPR_SANITIZE=0`.
+
+If you use `pandas` in your packages it is advisable you pin 
+
+`numexpr >= 2.8.6` 
+
+in your requirements.
