 Backport strategy
 -----------------
 
-We will always backport to the patch release branch (*v3.N.x*):
+Backports to the patch release branch (*v3.N.x*) are the changes that will be
+included in the next patch (aka bug-fix) release.  The goal of the patch
+releases is to fix bugs without adding any new regressions or behavior changes.
+We will always attempt to backport:
 
-- critical bug fixes (segfault, failure to import, things that the user cannot
-  work around)
-- fixes for regressions against the last two releases.
+- critical bug fixes (segfault, failure to import, things that the
+  user can not work around)
+- fixes for regressions introduced in last two minor releases
 
-Everything else (regressions against older releases, bugs/api
-inconsistencies the user can work around in their code) are on a
-case-by-case basis, should be low-risk, and need someone to advocate
-for and shepherd through the backport.
+and may attempt to backport regressions introduced in older releases.
+
+In the case where the backport is not clean, for example if the bug fix is
+built on top of other code changes we do not want to backport, balance the
+effort and risk of re-implementing the bug fix vs the severity of the bug.
+When in doubt, err on the side of not backporting.
+
+When backporting a Pull Request fails or is declined re-milestone the original
+PR to the next minor release and leave a comment explaining why.
 
 The only changes to be backported to the documentation branch (*v3.N.M-doc*)
-are changes to :file:`doc`, :file:`examples`, or :file:`tutorials`.
-Any changes to :file:`lib` or :file:`src` including docstring-only changes
-should not be backported to this branch.
