 # cpp11 (development version)
 
+* R >=3.5.0 is now required to use cpp11. This is in line with (and even goes
+  beyond) the tidyverse standard of supporting the previous 5 minor releases of
+  R. It also ensures that `R_UnwindProtect()` is available to avoid C++ memory
+  leaks (#332).
+  
+* `cpp11::preserved.release_all()` has been removed. This was intended to
+  support expert developers on R <3.5.0 when cpp11 used a global protection
+  list. Since cpp11 no longer uses a global protection list and requires R
+  >=3.5.0, it is no longer needed. As far as we can tell, no package was
+  actively using this (#332).
+
 * Nested calls to `cpp11::unwind_protect()` are no longer supported or
   encouraged. Previously, this was something that could be done for performance
   improvements, but ultimately this feature has proven to cause more problems
